Portable temporary turnout system for rails

A portable and temporary rail transition system for installation on a main track to guide rail equipment from parallel rails of the main track and onto parallel rails of a turnout track. The system includes rails of turnout track, turnout ties, and rail transition devices that are configured for mounting to the ties and over at least the parallel rails of the turnout track to facilitate guidance of wheels of the rail equipment away from the parallel rails of the main track and onto the parallel rails of the turnout track.

BACKGROUND

The present disclosure is generally related to railroad tracks. More specifically, this disclosure is related to a system used to guide rail equipment onto rails of a turnout track.

2. Description of Related Art

In order to transition rail equipment (e.g., locomotives, cars, trains) from a main line track, a turnout track can be installed. A turnout track can be used to guide equipment off of the main line track (e.g., into storage in a rail yard) and/or to redirect movement of the equipment.

The turnout track typically includes parallel rails that curve towards the right or left and are positioned adjacent to tracks of the main line track. Despite their direction of curvature, devices are required to connect the parallel rails of the turnout track to the rails of the main line track so that the equipment being moved is guided onto the parallel turnout rails. As is generally well known, switches can be used to alternately switch between tracks. In other cases, jumpers are used for transition to a turnout track. Bent pieces of rail can be provided over rails of a main line track as a switch point to allow equipment to jump or transition to the turnout track.

Alternatively, braces can be positioned relative to the main line track and, in some cases, placed directly on top of the existing rails of the main line track. That is, rails of a turnout track can be positioned over the rails of a main line, and braced to the existing track. Other devices, called “leap frogs,” are designed with a hinge, so that the leap frog can be alternately positioned over at least part of the turnout rails to guide the rail equipment from the main line track and onto the turnout track.

SUMMARY

Other aspects, features, and advantages of the present disclosure will become apparent from the following detailed description, the accompanying drawings, and the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

Disclosed herein is an engineering system that is configured for temporary installment of a parallel rail to form a turnout track from rails of a main line. Leap frogs or “rail transition devices,” as referred to herethroughout, are designed for installation on ends of curved tracks, secured with designed turnout ties, to assist in transitioning equipment to the turnout track. Additional features and advantages are noted throughout the description below. It is noted that, while the Figures illustrate the turnout track being applied to the main track in a generally curved, right to left configuration (i.e., turning towards the left relative to the direction of the main track), one of ordinary skill in the art understands that a similar system (including its parts, e.g., body portion, guide with ramps, etc., as described in further detail below) can be designed and to curve in a left to right configuration (i.e., turning towards the right relative to the direction of the main track) and provided within the same scope of this disclosure.

Shown inFIG. 1Ais a main track12comprising a first rail12A and a second rail12B. The first and second rails12A and12B are horizontally spaced and run parallel to each other. As is generally known, the rails12A and12B are secured in place using spaced ties16(e.g., made of wood) to form the main track12.

A portable and temporary rail transition system10is provided herein that is used for guiding rail equipment (e.g., rolling stock, vehicles such as cars, and/or way equipment) from the first and second parallel rails12A and12B of main track12to first and second parallel rails14A and14B of a turnout track14. The rail transition system includes a plurality of turnout ties18A-18L that are configured for positioning under the parallel rails12A and12B of the main track12, as well as under rails of the turnout track14. As illustrated inFIG. 1A, turnout ties18A-18L are positioned under the parallel rails of the main track12. The turnout ties18A-18L can replace pre-installed ties16provided under the parallel rails12A and12B of the main track12. That is, the pre-installed ties16are removed and replaced with the turnout ties18A-18L. The turnout ties18A-18L can be positioned in place of the removed installed ties and spaced relative to pre-installed adjacent ties.

The positions of the plurality of turnout ties18A-18L under the parallel rails12A and12B of the main track12and under rails of the turnout track14can be predetermined. For example, the placement and spacings S1, S2, S3, etc. between turnout ties18A-18L are based on the locations and spacing between pre-installed (existing) ties16under main track12. In one embodiment, each of the ties is spaced substantially equidistant to each other. In another embodiment, the spacing of the turnout ties may vary. In an embodiment, the turnout ties between rail transition devices are substantially equally spaced from each other. In another embodiment, the spacing between turnout ties may be based upon the length of the rail transition devices. For example, the relative spacing of turnout ties18A and18B and/or turnout ties18J and18K may be based on locations (which can be predetermined) for applying attachment devices to and/or along the length of a rail transition device. In one embodiment, the spacing between each of the ties is based on the curve radius of the turnout track14.

In the embodiment illustrated inFIG. 1A, turnout ties18C-18D,18D-18E,18E-18F,18G-18H, and18H-18I are positioned at a space S1relative to each other. In one embodiment, such as shown inFIG. 1A, each space between the illustrated turnout ties is measured from a centerline of one turnout tie to a center of another, adjacent turnout tie. In another embodiment, each space can be measured between sides of the turnout ties. For explanatory purposes only, the spaces and/or spacings S1-S4at which turnout ties are positioned relative to one or more adjacent turnout ties are understood herethroughout to mean a measurement taken substantially relative to a center portion of each turnout tie, i.e., from center to center. As shown inFIG. 1A, turnout tie18J is positioned at a space S2relative to turnout tie18I. Turnout tie18B is positioned at a space S3relative to turnout tie18C. Turnout tie18A is positioned at a space S4relative to turnout tie18B. Turnout tie18K is positioned at a space S4relative to turnout tie18J. Turnout tie18L is positioned at space S2relative to turnout tie18K.

InFIGS. 24-35, an exemplary embodiment of each of the turnout ties18A,18B,18C,18D,18E,18F,18G,18H,18I,18J,18K, and18L for use with the system are illustrated. A length, width, and other features associated with each of the turnout ties is determined based on the turnout track14being installed, as well as their intended placement along a length of the main track12, e.g., in a longitudinal direction. In accordance with one embodiment, the placement of each of the turnout ties in place of the pre-installed ties16under the main track is predetermined. That is, the turnout ties can be labeled and/or provided for installation in a predetermined order (e.g., numbered) so that the system is correctly installed and implemented, and so that the ties are configured to align with the rails on both the main track12and turnout track14when installed.

As shown, each tie18A-18L can include either attachment plates22or turnout plates20, or both on at a least a top surface thereof. The turnout plates20and attachment plates22are used to connect with one or more of the rails (e.g.,12A,12B,14A, and/or14B) and/or parts of the rail transition devices100,200,300, and400. In an embodiment, a combination of two to four turnout plates20and/or attachment plates22can be provided on each turnout tie. Each of the turnout plates20may include a space24therein for receiving and securing an object, e.g., a rail, much like attachment plates22. The space24can be positioned a variable distance DT from an end of each tie depending on its placement along the length of the main track12and within the system. Each of the turnout plates22can be provided an angle relative to the top of the tie itself. Also, as shown, the placement and spacing between the turnout plates20and/or attachment plates22on top of each of the ties18A-18L varies depending on the placement of the tie itself. In accordance with an embodiment, the turnout plates20and attachment plates22are provided on a relative turnout tie based on their intended placement under the main track12. Thus, the predetermined order of the turnout ties further ensures that the rails of the main track12and turnout track14can be properly secured.

However, it should be noted that the number of turnout ties18A-18L is not necessary limited to twelve, as shown inFIGS. 24-35. The number of ties, turnout plates20, and attachment plates22, as well as their spacing and length, and dimensions of the ties and plates, can vary and can be altered based on the length and/or curvature of the turnout track14, for example. Each turnout tie is configured for attachment to at least a portion of the main track and the turnout track thereto, but does not necessarily need to be attached to both rails of either or both tracks12and14. Accordingly, it should be understood to one of ordinary skill in the art that the number and design of each of the turnout ties used to replace pre-installed ties under the main track12is not meant to be limiting.

Referring back toFIG. 1A, the turnout track14includes first and second curved rails14A and14B that configured for positioning adjacent to the rails12A and12B of the main track12in parallel alignment therewith. More specifically, the first curved rail14A is formed from a first transition rail14T1and a second transition rail14T2. The first transition rail14T1has a first end15and a second end17and is configured for placement between the parallel rails12A and12B of the main track12such that the first end15is adjacent the first rail12A of the main track12and the second end17is adjacent the second rail12B of the main track12, as shown. The second transition rail14T2is configured for positioning adjacent to an outside of the second rail12B of the main track12. The first and second transitional rails14T1and14T2are parallel to rail14B and collectively form the curved rail14A, albeit with a space between the ends of rails14T1and14T2for rail12B. The second curved rail14B is configured for positioning parallel to the first and second transition rails14T1and14T2, respectively, adjacent to the outside of the second rail12B of the main track12for curving away therefrom.

It should be noted that the rails14A and14B of the transition track14are configured such that when positioned relative to the rails12A and12B of the main track12, there is a gap or clearance between ends of the rails. For example, such a clearance is provided at first end15of first transition rail14T1relative to (a side of) rail12A, at second end17of first transition rail14T1relative to (a side of) rail12B, an end of second transition rail14T2relative to rail12B, as well as an end of second rail14B relative to rail12B. A user can align the rails14A and14B such that the gap or clearance is satisfied. The rails14A and14B can then be clipped or secured (e.g., using clips or other mechanical devices) along with rails12A and12B to the ties to remain in place. The gap or clearance between the adjacent rails allows the rails12A and12B and rails14A and14B to remain in place even if the rail transition devices100-400are not installed, so that train traffic can utilize the rails12A and12B of the main track12. That is, the gap or clearance allows a train to run on the main track12, since the wheels of the trains can pass between the two existing rails12A and12B and the turnout rail14A and14B by running through the gaps and between the rails. In an embodiment, the gap or clearance is approximately 5 inches.

In an embodiment, the turnout track14has a curve radius of or between approximately five degrees to approximately ten degrees. In one embodiment, the curve radius of the turnout track14is approximately nine degrees. The curve radius can be fixed or revised, as needed.

The length of the first transition track14T1is based on the curve radius of the turnout track14. Referring toFIG. 1, for example, assuming the curve radius of the turnout track14is designed to be fixed at approximately nine degrees, the length of the first transition track14T1is approximately 39 feet.

In addition to the turnout ties18A-18L and rails of the transition track14, the rail transition system10includes, as shown inFIG. 1B, a first set21of rail transition devices100and200and a second set23of rail transition devices300and400. When installed and configured for use, the first set21of rail transition devices100and200is configured to guide wheels of rail equipment away from the parallel rails12A and12B of the main track12(and towards and onto the parallel rails14A and14B of the turnout track14), and the second set23of rail transition devices300and400is configured to guide wheels of the rail equipment onto the parallel rails14A and14B of the turnout track14.

As shown, the first set21is configured for mounting over the parallel rails12A and12B of the main track12and the parallel rails14A and14B of the turnout track14. Specifically, rail transition device100of the first set21is configured for mounting over the first end15of the first transition rail14T1. Rail transition device200of the first set21is configured for mounting over an end of the second curved rail14B adjacent to the outside of the second rail12B of the main track12. The second set23is configured for positioning along the turnout track14and spaced a distance S longitudinally relative to the first set21for mounting over the turnout track14. Specifically, rail transition device300is configured for mounting over the second end17of the first transition rail14T1, and rail transition device400is configured for mounting over at least a portion of the second curved rail14B.

The distance S between the sets21and23can be measured between ends of the rail transition devices, for example. In an embodiment, the distance S between first set21and second set23is approximately 50 feet. In another embodiment, the distance S is approximately 30 feet. In yet another embodiment, the distance S between first set21and second set23can be within a range of approximately 20 feet (inclusive) to approximately 60 feet (inclusive).

Each rail transition device100,200,300, and400of the first and second sets21and23is configured for attachment to predetermined ties of the plurality of turnout ties when positioned under the main and turnout tracks12and14. That is, as noted above and shown inFIGS. 24-35, the turnout ties18A-18L can be formed with turnout plates22and attachment plates20for their attachment to rails of the tracks12and/or14, as well as for attachment to one or more of the rail transition device(s)100,200,300, and/or400. In accordance with one embodiment, as explained in detail later, the rail transition devices100,200, and300are configured for vertical adjustment relative to the rails14A and14B of the turnout track14(e.g., when being assembled and installed).

Each rail transition device100,200,300, and400comprises a body portion60and leg portions30. Such features can be generally seen inFIGS. 2 and 3, for example. The body portion60of each rail transition device100,200,300, and400has a longitudinal surface and arm portions61extending downwardly therefrom. The longitudinal surface and arm portions can be formed integrally together or assembled to form an integral part (e.g., welded together). Arm portions61are attached to an underside of its ends and positioned perpendicularly to the longitudinal surface. Arm portions61are configured for alignment with and attachment to leg portions30positioned on either side of the body portion60. Generally, the body portion60comprises an upside-down “U”-shape.

In accordance with another embodiment, body portion60includes integrally formed arm portions61that are used as leg portions30on either of its sides (e.g., seeFIG. 23).

As shown inFIG. 8, the body portion60has an overall height HB (measured from a top of longitudinal surface to a bottom of arm portion61) and an overall width WB (measured in a lateral direction across the longitudinal surface, from arm portion61to arm portion61). In one embodiment, the height HB is approximately 5½ inches. In an embodiment, the width WB is between approximately 18 inches (inclusive) and approximately 30 inches (inclusive). In one embodiment, the width WB is approximately 20 inches. In another embodiment, the width WB is approximately 25 inches. In yet another embodiment, the width WB is approximately 28 inches.

The longitudinal surface of each body portion60has a ramped guide portion62provided thereon, with ramps66at either end. Each body portion60is configured for mounting over at least a portion of the turnout track14such that at least one of its ramps66of its guide portion62are aligned with at least one rail14A or14B of the turnout track14(e.g., seeFIG. 1A). Guide portions62may be provided at an angle relative to the longitudinal surface, for example, based on the angle of the rail it is aligned with. Ramps66extend from each of the ends of the guide portion62and are angled (vertically) relative to the rail. Each guide portion62A has a first (e.g., front or entrance) and a second (e.g., back or exit) ramp66extending a length LR from the ends of the body60, each of which are configured for alignment with and placement on rails. Ramps66provide smooth entry and exit as a vehicle or rail equipment moves along the longitudinal surface of the associated rail transition device. The ramp66acts as the surface upon which the treat portion of a wheel is able to travel over the existing track structure. At least one of the ramps66(e.g., a second or exit ramp) is configured for alignment with a rail of the turnout track14(e.g., seeFIG. 2) and, when the devices are installed, configured to guide wheels of rail equipment from rails12A and12B of the main track12at an angle and onto the guide portions62of each of its relative rail transition device, so that the wheels are guided towards and along the parallel rails14A and14B of the turnout track14. In an embodiment, the angles of the ramps66for each rail transition device are similar. In another embodiment, the angles of the first (e.g., front or entrance) ramps for each rail transition device are similar. In another embodiment, the angles of the second (e.g., back or exit) ramps for each rail transition device are similar. The angles of the first ramps66can be different from the second ramps66. As an example, the angle of entry and/or exit using ramps66may be between approximately 15 degrees (inclusive) and approximately 35 degrees (inclusive).

A length LF of the longitudinal surface of each of the body portions (see LF1inFIG. 10, LF2inFIG. 14, etc.) of each rail transition device (not including a length of each of the ramps66) can vary depending on the placement of the respective device along on the turnout track. In accordance with an embodiment, the overall length LF of the body portion is within a range of approximately 100 inches (inclusive) to approximately 130 inches (inclusive). Each of the ramps66extends a length LR from the ends of the body portion60. In accordance with one embodiment, the length LR of a ramp66is within a range of approximately 10 inches (inclusive) to approximately 12 inches (inclusive). An overall length LT (not shown) of each body portion may include the length LF of the body portion as well as the length of ramp66extending therefrom. A width WT of the body portions can also vary depending on the placement of the respective device along on the turnout track.

Overall length LT and overall width WT of each the rail transition devices100,200,300, and400, alternatively including the lengths/widths of their respective ramps, can vary depending on the placement of the device on the turnout track. In accordance with an embodiment, the overall length LF of a rail transition device is within a range of approximately 145 inches (inclusive) to approximately 150 inches (inclusive). In accordance with an embodiment, the overall width WT of a rail transition device is within a range of approximately 28 inches (inclusive) to approximately 40 inches (inclusive).

To assist in guiding wheels of rail equipment towards the rails14A and14B of the turnout track14and to guard from displacement of the wheels from the guide portion62by balancing rail equipment, each transition device100,200,300, and400further includes a guard rail64thereon, as shown inFIGS. 2 and 3. Each guard rail64runs parallel to each guide portion62on the top of the longitudinal surface of the body portion60. The guard rail64is provided on an internal side of the longitudinal surface relative to the rail(s) that the ramps66are aligned with. A space or flangeway70is provided between the guide portion62and the guard rail64is configured to at least partially receive wheels of the rail equipment for their travel along the respective device and to reduce and/or eliminate displacement and/or imbalance, and to guide the wheels along the guide portion62(e.g., seeFIGS. 10,14,18, and21). That is, the guard rail64acts as a safety device to ensure that if the wheels do not enter the ramp66in a correctly oriented fashion, the guard rail64forces the flange of the wheel into the space or flangeway70between the ramp66and the guard rail64. For example, a first axle of a piece of equipment may align and have its wheels be guided along guide portion62in an acceptable manner, while a second axle of the equipment can have a tendency to turn or twist relative to the rail transition device. As the wheels on each axle go into the flangeway70, the wheels are aligned between the guide portion62and the guard rail64, ensuring alignment of the wheels on each of the axles for guidance by the rail transition device.

Leg portions30of each rail transition device100,200and300are configured to be removably connected to the body portion60and to the selected predetermined ties of the plurality of turnout ties18A-18L, in accordance with an embodiment. Once installed to its designated turnout tie(s), each leg portion30is static. As shown inFIGS. 2,3, and8, for example, in one embodiment, each of the leg portions30is an “L”-shaped bracket comprising a horizontal portion32and a vertical portion34. The vertical portion34is substantially perpendicular to the horizontal portion32. The horizontal portion32is configured for connection to one of the predetermined ties of the plurality of turnout ties18A-18L, and the vertical portion34is configured for connection to the body portion60. More specifically, the vertical portion34is configured for connection with an arm portion61of the body portion60. To attach each arm portion61with vertical portion34of each leg portion30, a plurality of holes (not shown) can be spaced longitudinally along a length of the arm portion61. A plurality of attachment bolts38(or other fasteners) are provided through each of the holes of the arm portions61, and thus are provided in a spaced configuration along a length of the arm portion61. The attachment bolts38extend laterally from each arm portion61(e.g., seeFIG. 3). The attachment bolts38are configured for receipt through a corresponding slot, for example, in the aligned leg portions30. In accordance with an embodiment, the leg portions of at least one the rail transition devices100,200, and/or300include adjustment slots36configured to enable vertical adjustment of the body portion60relative to the leg portions30and the rails of the turnout track. Collectively, the leg portions30and arm portions61permit each rail transition device to be adjusted vertically. Vertical adjustment of the leap frog ensures that various rail sizes can be accommodated. In the Figures, each of rail transition devices100,200, and300have adjustment slots36in their leg portions30. The plurality of adjustment slots36are vertically elongated and provided in a spaced configuration along a length of the vertical portion34of each leg portion30. Each attachment bolt38of arm portion61can be aligned with and inserted through each adjustment slot36of the vertical portion34and secured with a nut40(seeFIG. 6) in a selected position along the length of the slot.

In accordance with an embodiment, a rail transition device need not include adjustment slots36and/or attachment bolts28for vertical adjustment. Vertical adjustment relative to a rail may not be required. For example, as explained in greater detail below with respect toFIG. 23, rail transition device400may be manufactured with attached leg portions30(or arm portions61) to form a single piece body portion60D designed for placement over and alignment with a rail (e.g., rail14B).

As shown inFIG. 8, each leg portion30has an overall height HL (measured from a top of vertical portion34to a bottom of horizontal portion32) and an overall width WL (measured in a lateral direction along a bottom of horizontal portion32). In an embodiment, the height HL is between approximately 5 inches (inclusive) and approximately 8 inches (inclusive). In one embodiment, the height HL is approximately 7 7/16 inches. In another embodiment, the height HL is approximately 5½ inches. In yet another embodiment, the height HL is approximately 7¾ inches. In an embodiment, the overall width WL is approximately 5 inches. In one embodiment each of the horizontal portion32and vertical portion34has a thickness of approximately 1 inch.

In another embodiment, angled end portions58are further associated with leg portions30. For example, as further described below and shown inFIG. 18, a body portion60and/or leg portions30may include angled areas at ends thereof to accommodate, for example, a curvature of rails and positioning of a rail transition device for proper alignment with an attachment to a turnout tie.

Attachment brackets28can be used with system100to connect the horizontal portion32of each of the leg portions30to the predetermined turnout ties. As shown in greater detail inFIGS. 4 and 5, each attachment bracket28includes a securement plate44with a male extension portion48extending upwardly therefrom. The securement plate44comprises a length L and a width W (seeFIG. 4) and a height (seeFIG. 5). In accordance with one embodiment, the securement plate44is substantially square in shape. That is, length L and width W are substantially equal in dimension. In one embodiment, length L and width W of the securement plate44are approximately 8 inches. In an embodiment, the height H of the securement plate44is approximately 1 inch. One or more bolt receiving slots46extend through the securement plate44. Slots46are configured to receive a bolt49(or other similar fastener device) therethrough in order to secure the securement plate44of the attachment bracket28to a predetermined turnout tie, as shown inFIG. 7.

The extension portion48has a slot50extending therethrough. As shown inFIG. 5, the slot may be positioned at a distance D1from a top of the securement plate44. The width D or diameter of the slot50is not limiting. In one embodiment, the width D is approximately 1⅛ inches. In another embodiment, the width D of the slot50is based on the width or diameter of the locking device (e.g., pin54, noted below) inserted therethrough.

The horizontal portion32of each leg portion30has at least one receiving (female) opening52configured for alignment with and to receive the (male) extension portion48of the attachment bracket28therethrough. As shown inFIGS. 3 and 6, for example, the extension portion48is aligned with and inserted upwardly through receiving opening52such that the slot50can be used to secure the leg portion30and the attachment bracket28together. In accordance with an embodiment, shown inFIG. 7, a pin54is configured for insertion through the slot50of the extension portion48of the attachment portion28to act as a locking device. A pin54can be provided for each attachment bracket28used to attach the associated rail transition device. The pin54is a mechanical fastening device used to ensure that its rail transition device, once installed, do not move vertically, longitudinally or laterally relative to the top surface of the tie it is attached to. The design of the pin54is not meant to be limiting and is an example device that can be used for securing the parts. Other devices, such as clips or fasteners, may alternatively be used. Referring back toFIG. 7, after the extension portion48is received by the horizontal portion32, as shown, the pin54can be aligned with and slid (e.g., in a horizontal direction) through slot50. Optionally, pin54has a handle56attached thereto for easier insertion and removal of the pin54relative to the extension portion48(seeFIG. 7).

In accordance with an embodiment, at least two receiving openings52are provided along a length of each horizontal portion32. Accordingly, at least two attachment brackets28are used to connect each leg portion30, i.e., a total of four attachment brackets28are used to connect a rail transition device to predetermined turnout ties. However, the number of attachment brackets28and openings52in leg portions30is not meant to be limiting. Further, although not shown, it is within the scope of this disclosure that the leg portions30may optionally be attached to existing ties16under the main track12.

The positioning of the receiving openings52along the leg portions30is not limiting. In accordance with an embodiment, the receiving openings52are positioned approximately 12 inches to approximately 18 inches from an adjacent end of the leg portion.

In addition, in an embodiment, the body portion60is vertically adjustable relative to the leg portions30and the rails14A and14B of the turnout track14. For example, in some cases, the height of the rails upon which each rail transition device is installed can vary, e.g., based upon the sizes of the rails (e.g.,110#,141#) vary the height of the top of the rail. Thus, the height or elevation of the body portion60may need to be adjusted (in the vertical direction, upwardly or downwardly) in order to properly align the ramps66on either side with their respective rail to achieve the required elevation. An elevation of at least the body portion60of some or each of the rail transition devices can be adjusted to accommodate rail sizes. To enable vertical adjustment of the body portion60, the vertically elongated adjustment slots36along each leg portion30comprises a height HS, as shown inFIG. 6. The height HS of each adjustment slot36can therefore substantially correspond to an amount of vertical adjustment of the relative body portion60. In one embodiment, the height HS is approximately 1½ inches (inclusive) to approximately 4 inches (inclusive). In an embodiment, the height HS of each adjustment slot36is approximately 2½ inches. In an embodiment, each adjustment slot36is sized with dimensions (e.g., height HS) to accommodate a height adjustment between rail heights of approximately 5 41/64 inches and approximately 7 7/16 inches.FIG. 8shows an end perspective view of a rail transition device with arrow A indicating relative vertical movement or adjustment of the body portion60to the L-shaped leg portions30. Nuts40are loosened to adjust elevation of body portion60. Once moved to a desired position, each nut40for each attachment bolt38extending through the arm portions61is tightened to secure body portion60to leg portion30.

In an embodiment, each adjustment slot36is sized with width dimensions based on the type of attachment bolt to be used. In one embodiment, each of the attachment bolts38is a 1″ A325 Type 3 bolt. In accordance with one embodiment, the adjustment slots36have a width of approximately 1⅛ inches.

Optionally, one or more of the rail transition devices further comprises a structure thereon configured for receipt of a device for lifting and moving the rail transition device relative to the track to install or remove the rail transition device from the track structure. As shown inFIGS. 3 and 6, for example, a structure in the form of an eye bolt42may be provided on or more of the leg portions30. For example, an eye bolt may be provided at each end of each leg portions, i.e., two eye bolts per leg portion, four eye bolts per rail transition device (e.g., one in each corner).FIG. 9shows an alternate embodiment of an optional eye bolt42that can be used. The eye bolt(s)42can be used as pick points to enable safe lifting and transportation of a rail transition device within a yard and along a track. Despite its design, each eye bolt42can have a base43with a rounded portion45attached thereto and generally extending vertically therefrom. An opening47is provided through rounded portion45. The opening47is configured to receive chains or other devices, for example, when lifting and moving rail transition devices to a designated area along a track for installation.

The optional eye bolt42can have an overall length L2, width W2, thickness, T2, and its opening47can have a width D2or diameter. In an embodiment, the length L2is not greater than a height of the vertical portion34of leg portion30(e.g., so as not to extend above the longitudinal surface of body portion60). In one embodiment, the length L2is approximately 6 inches. In one embodiment, the width W2is approximately 5 inches. In one embodiment, the thickness T2is approximately 1 inch. In one embodiment, the width D2of the opening47is approximately 3 inches.

Also optionally associated with a body portion60of a rail transition device is a stiffener68, as shown inFIGS. 12 and 16, for example. Stiffener68aids in substantially reducing and/or substantially eliminating warping and deformation along at least the length of the body portion60when a rail transition device is installed on top of a rail. Stiffener68is provided on an underside of the longitudinal surface of a body portion60. More specifically, stiffener68can be angularly aligned (on the underside of the longitudinal surface) for placement substantially on top of the rail. Stiffener68can also be angularly aligned (on the underside of the longitudinal surface) with the ramped guide portion62(on the upper or top side of the longitudinal surface). In one embodiment, stiffeners68are associated with at least the first set21of rail transition devices100and200. A stiffener68may also be provided with rail transition device300. In an embodiment, the stiffener is formed from a steel beam.

The stiffener68may be attached to an underside of the body portion60using welding or other methods, for example. In one embodiment, the stiffener68is welded to the underside of the longitudinal surface of body portion60with a continuous weld (e.g., 5/16″ fillet weld).

Stiffener68has an overall length LST and a width W4. Also, the stiffener may include a reduced or angled portion along its length that has a length LP and a width W3. The reduced portion of the stiffener is positioned relative to the width of the body portion60a distance D3from one of the leg portion30(e.g., seeFIG. 12) when aligned at an angle with the guide portion62of the body portion60. The reduced portion of the stiffener is positioned relative to the length of the body portion60a distance D4from an end of the body portion60, as also shown inFIG. 12. The stiffener can be formed from a stock piece of steel that is approximately 3 inches×3 inches×approximately 12 inches (inclusive) to approximately 22 inches (inclusive). In one embodiment, the overall length LST of the stiffener is approximately 60 inches. In one embodiment, the width W4is approximately 5 inches. The length LP of the reduced portion is between approximately 28½ inches (inclusive) and approximately 29½ inches (inclusive). In one embodiment, the width W3of the reduced portion is approximately 3¼ inches. In an embodiment, the distance D3between a leg portion and an end of the stiffener (along a width of the body portion60) is between approximately 12 inches (inclusive) and approximately 14 inches (inclusive). In an embodiment, the distance D4between an end of the body portion and the reduced portion (along a length of the body portion60) is between approximately 38 inches (inclusive) and approximately 42 inches (inclusive).

In accordance with an embodiment, the features associated with each of the four transition devices100,200,300, and400can be designed based on the curve radius of the turnout track14being used as well as their configured location for placement relative to the turnout track14. For example, details regarding each of the rail transition devices associated with a turnout track having a curve radius of nine degrees can be seen inFIGS. 10-23.

FIGS. 10-13illustrate top, side, bottom, and end views of first rail transition device100of the system100, in accordance with one embodiment. First rail transition device100comprises a body60A with guide portion62A and guard rail64A positioned on a top of its longitudinal surface, as shown inFIG. 10, with connected leg portions30on either of its sides. Body60A has a longitudinal length LF1of approximately 126 inches. Guide portion62A is positioned at an angle relative to the elongated body portion60A. Guide portion62A has a first (e.g., front or entrance) and second (e.g., back or exit) ramps66A and66B each extending a length LR from the ends of the body60A, each of which are configured for alignment with and placement on rails (e.g., first rail12A of main track12and first transition rail14T1of first curved rail14A of turnout track14, as shown inFIG. 1B). The length LR of the ramps66A and66B is between approximately 11½, inches (inclusive) and approximately 12 inches (inclusive). Each of the ramps66A and66B of the guide portion62A is positioned at an angle relative to the elongated body portion60A, and can vary as previously noted, in order guide wheels upon entry onto the elongated body portion60A and exit therefrom. The space or flangeway70between the guide portion62A and guard rail64A is approximately 2¼ inches.

Four adjustment slots36are provided in the leg portions30of first rail transition device100(e.g., seeFIG. 11). Accordingly, four attachment bolts38are inserted through the corresponding holes in the arm portions61(not shown) and are provided and inserted through the slots36. The slots36are provided a distance or length LB1from each end of the leg portion30, and a distance or length LB2relative to each other, as shown inFIG. 11. In an embodiment, the distance LB2is approximately 12 inches, and the distance LB2between each slot36is approximately 34 inches. Receiving openings52are also provided in leg portions30(e.g., seeFIG. 10) to align with attachment brackets28and to connect the device to predetermined turnout ties. Additionally, the location of receiving openings52on leg portions30can vary. In an embodiment, the receiving openings52are provided a distance or length LB3from each end of the leg portion30to a center of the opening52, as shown inFIG. 11. In an embodiment, the distance LB3is within a range between approximately 12 inches (inclusive) and approximately 24 inches (inclusive). In another embodiment, the distance LB3is approximately 17 inches. In yet another embodiment, the distance LB3is approximately 14 inches. In still yet another embodiment, each receiving opening52may be provided at difference distances LB3from the end of the leg portion30. For example, one receiving opening52can be approximately 14 inches from a first end of a leg portion30, while another receiving opening52can be approximately 17 inches from a second end of the leg portion30. Accordingly, the spacing or distances of the slots36and receiving openings52may vary.

Stiffener68A is provided on an underside of the longitudinal surface of the body60A, as shown inFIG. 12, angularly in line with the guide portion62A (guide portion62A being on a top surface thereof, and stiffener68A underneath or on an underside of the body60A). The reduced portion of the stiffener is positioned a distance D3of approximately 12½ inches from leg portion30along the width of the body portion60A, and is positioned a distance D4of approximately 39 inches from an end of the body portion60A. Stiffener68A has an overall length LST of approximately 60 inches, width W4of approximately 5 inches, length LP of reduced portion of approximately 29 1/16 inches, and width W3of reduced portion of approximately 3¼ inches.FIG. 13illustrates an end view of the first rail transition device100.

FIGS. 14-17illustrate top, side, bottom, and end views of second rail transition device200of the system100, in accordance with one embodiment. Second rail transition device200comprises a body60B with guide portion62B and guard rail64B positioned on a top of its longitudinal surface, as shown inFIG. 14, with connected leg portions30on either of its sides. Body60B has a longitudinal length LF2of approximately 126 inches. Guide portion62B is positioned at an angle relative to the elongated body portion60B. Guide portion62B has a first (e.g., front or entrance) and second (e.g., back or exit) ramps66C and66D each extending a length LR from the ends of the body60B, each of which are configured for alignment with and placement on rails (e.g., second rail12B of main track12and second curved rail14B of turnout track14, as shown inFIG. 1B). The length LR of the ramps66C and66D is between approximately 8 7/32 inches (inclusive) and approximately 12 inches (inclusive). Each of the ramps66C and66D of the guide portion62B is positioned at an angle relative to the elongated body portion60B, and can vary as previously noted, in order guide wheels upon entry onto the elongated body portion60B and exit therefrom. The space or flangeway70between the guide portion62B and guard rail64B is approximately 2¼ inches.

Like first rail transition device100, four adjustment slots36and four attachment bolts38can be provided in second rail transition device200(e.g., seeFIG. 15). Receiving openings52are also provided in leg portions30(e.g., seeFIG. 14) to align with attachment brackets28and to connect the device to predetermined turnout ties. Since the dimensions LB1, LB2, LB3, etc. associated with the slots36and bolts38and openings52for second rail transition device200are substantially similar to first rail transition device100, as shown, their description and alternatives are therefore are not repeated.

Stiffener68B is provided on an underside of the longitudinal surface of the body60B, as shown inFIG. 16, angularly in line with the guide portion62B (guide portion62B being on a top surface thereof, and stiffener68B underneath or on an underside of the body60B). The reduced portion of the stiffener is positioned a distance D3of approximately 12 7/16 inches from leg portion30, and is positioned a distance D4of approximately 41 inches from an end of the body portion60B. Stiffener68B has an overall length LST of approximately 60 inches, width W4of approximately 5 inches, length LP of reduced portion of approximately 28 13/32 inches, and width W3of reduced portion of approximately 3¼ inches.FIG. 17illustrates an end view of the second rail transition device200.

FIGS. 18-20illustrate top, side, and end views of a third rail transition device300of the system100, in accordance with one embodiment. Third rail transition device300comprises a body60C with guide portion62C and guard rail64C positioned on a top of its longitudinal surface, as shown inFIG. 18, with connected leg portions30on either of its sides. Body60C has a longitudinal length LF3of approximately 102 inches. Guide portion62C can be positioned at an angle relative to the elongated body portion60C. In accordance with another embodiment, guide portion62C runs substantially parallel to arm portions61of body portion60C. Guide portion62C has a first (e.g., front or entrance) and second (e.g., back or exit) ramps66E and66F each extending a length LR from the ends of the body60C, each of which are configured for alignment with and placement on rails (e.g., first transition rail14T1of first curved rail14A of turnout track14and second transition rail14T2of second curved rail14B of turnout track14, as shown inFIG. 1B). The length LR of the ramps66E and66F is between approximately 10¾ inches (inclusive) and approximately 11 23/32 inches (inclusive). Each of the ramps66E and66F of the guide portion62C is positioned at an angle relative to the elongated body portion60C, and can vary as previously noted, in order guide wheels upon entry onto the elongated body portion60C and exit therefrom. The space or flangeway70between the guide portion62C and guard rail64C is approximately 2¼ inches.

Like first and second rail transition devices100and200, four adjustment slots36and four attachment bolts38can be provided in third rail transition device300(e.g., seeFIG. 19). Receiving openings52are also provided in leg portions30(e.g., seeFIG. 18) to align with attachment brackets28and to connect the device to predetermined turnout ties. Since the dimensions LB1, LB2, LB3, etc. associated with the slots36and bolts38and openings52for third rail transition device300are substantially similar to first rail transition device100and second rail transition device200, as shown, their description and alternatives are therefore are not repeated.

However, it is noted that leg portions30of third rail transition device300as shown inFIGS. 18-20include angled end portions58on at least its leg portions30. In accordance with an embodiment, body portion60C may also include end portions58that are angled relative to its elongated body. Each angled end portion58is angled relative to the elongated structure of the horizontal leg extensions32of each leg portion30. As previously noted, these end portions58can be provided at an angle in order to accommodate, for example, a curvature of rails and/or a positioning of a rail transition device on top of a turnout tie, so that it can be properly aligned with one or more turnout ties for attachment thereto. Moreover, as shown inFIG. 20, the elongated structures of the leg portions30and body portion60can be positioned at an angle.

Also, in an embodiment, a stiffener (not shown) can provided on an underside of the longitudinal surface of the body60C, and may be angularly in line with the guide portion62C (guide portion62C being on a top surface thereof, and stiffener underneath or on an underside of the body60C).

FIGS. 21-23illustrate top, side, and end views of a fourth rail transition device400of the system100, in accordance with one embodiment. Fourth rail transition device400comprises a body60D with guide portion62D and guard rail64D positioned on a top of its longitudinal surface, as shown inFIG. 21. Body60D has a longitudinal length LF4of approximately 126 inches. Guide portion62D is positioned at an angle relative to the elongated body portion60D. Guide portion62D has a first (e.g., front or entrance) and second (e.g., back or exit) ramps66G and66H each extending a length LR from the ends of the body60D, each of which are configured for alignment with and placement on rails (e.g., first transition rail14T1of first curved rail14A of turnout track14and second transition rail14T2of second curved rail14B of turnout track14, as shown inFIG. 1B). The length LR of the ramps66G and66H is approximately 12 inches. Each of the ramps66G and66H of the guide portion62D is positioned at an angle relative to the elongated body portion60D, and can vary as previously noted, in order guide wheels upon entry onto the elongated body portion60D and exit therefrom. The space or flangeway70between the guide portion62D and guard rail64D is approximately 1½ inches.

Unlike the previously described rail transition devices100,200, and300, in accordance with one embodiment, fourth rail transition device400has connected arm portions61rigidly fixed to the body portion60D and that are used as the leg portions30on either of its sides. That is, there are no adjustment slots36in its leg portions and/or attachment bolts38provided in fourth rail transition device400(e.g., seeFIG. 22), because the body portion60D and leg portions30are connected directly together and form a single structure. Because the fourth rail transition device400is assembled relative to and in line with rail14B of the turnout track14, vertical adjustment of the body portion60D to accommodate a height adjustment between existing rail heights (between approximately 5 41/64 inches and approximately 7 7/16 inches) is not necessarily required. For example, because an existing main track12may have varied rail dimensions and/or some vertical wear, e.g., due to its previous use, vertical adjustment capabilities on body portions60A,60B, and/or60C can allow for adjustment relative to an existing main line track12to accommodate such dimensional variances. Device400does not necessarily require vertical adjustment because the rail (i.e., second curved rail14B of turnout track14) on which it is installed is substantially new and thus can be manufactured to accommodate the dimensions of the rail14B in which it is aligned. The height of the rail14B on which device400sits on does not need vary relative to the rail14B on which it is installed.

In one embodiment, the body portion60D and leg portions30are formed integrally together. In another embodiment, parts of the body portion60D and/or leg portions30are manufactured and rigidly connected together (e.g., via welding or bonding) to form a single piece.

However, it should be noted that in accordance with another embodiment, fourth rail transition device400can be manufactured to at least vertical adjust, e.g., using similar configurations (e.g., separate leg portions30and arm portions61, with adjustment slots36and bolts38) as described above, and thus should not be limited. In one embodiment, it is envisioned that fourth, rail transition device400includes a body portion60D and separate leg portions30that are aligned and secured together, such as shown inFIG. 14or18, for example.

Receiving openings52are also provided in leg portions30of fourth rail transition device400(e.g., seeFIG. 21) to align with attachment brackets28and to connect the device to predetermined turnout ties. Since the dimensions related to openings52for fourth rail transition device400are substantially similar the previously described rail transition devices100,200, and300, as shown, their description and alternatives are therefore are not repeated.

FIG. 23shows an end view of device400. Unlike devices100,200and300device400does not require a stiffener because the underside of device400rests on top of the rail14B. Thus, the rail14B below device400, when it is installed thereon, acts as the stiffener. Accordingly, placement and installment of the body portion60D on the rail14B allows the rail14B to aid in reducing and/or eliminating warping along the overall length of the device.

Accordingly, the herein described rail transition system100provides rail transition devices (or leap frogs) that are configured for mounting over rails of a main track and part of an included transition track without application or bracing above the existing main track. Rather, the disclosed devices are positioned inside the cribs (between the ties). This allows for at least temporary of a turnout rail without potentially damaging the existing track. Thus, damage is substantially reduced and/or substantially eliminated when the disclosed system is installed. Additionally, installation of the herein disclosed system100does not require any type of modification (e.g., rails being cut) of the existing track (main track12). Previous systems also require extensive installation of support structures (i.e. jacks) but this system100does not require an extensive support structure(s). Further, the system100can include customized rail transition devices based on the curve radius of the turnout rail desired. Each of the rail transition devices and the turnout ties can be assigned a predetermined installation location, so that the installation process is made easier. Moreover, the system100is provided as a packaged design that is configured for easier installation (and later removal) to an existing main track.

To install the parts of the portable and temporary rail transition system100described above to a main railroad track in order to provide a turnout track14for guiding rail equipment from parallel rails of the main track to parallel rails of a turnout track, a suitable place to install the portable turnout track is located. The parts of the rail transition system100, e.g., turnout ties18A-18L, rails14A (14T1and14T2) and14B of the turnout track14, and rail transition devices100-400can be designed and manufactured based on the desired curve radius of the turnout track, for example.

The method for installation of the rail transition system100includes installing the plurality of turnout ties under the parallel rails of the main track. This may include first marking (manually) each turnout tie location along the main track12utilizing spacing specifications of printed instructions provided with the turnout ties. Optionally, the top of the rails can be marked to aid in aligning the ties during their installation. The turnout ties can be numerically ordered adjacent to their assigned spaces or locations for easier access.

Existing spikes and/or anchors on existing ties are removed so that the existing ties under the main track can be removed (e.g., using a backhoe). The holes are cleaned out for receipt of the assigned turnout tie. Once the noted existing ties are removed, the turnout ties are installed in place thereof. Starting with each tie, e.g., tie #1-tie18A, tie #2-tie18B, etc., the turnout tie is placed into the hole under the rails of the main track12and lined up with the marks made on the (top of the) rails of the main track12. After each tie is in place and lined up (e.g., using optional alignment marks on the ties), the tie is nipped up and each of the twelve ties18A-18L is secured.

Once all of the turnout ties are installed, the rails14A and14B of the turnout track14are set. Optionally, the rails14A and14B may be marked (e.g., with paint) to provide a code (e.g., color code) for placement and alignment with the turnout ties. Nonetheless, the process includes: installing the first curved rail14A by positioning the first transition rail14T1between the parallel rails12A and12B of the main track12such that its first end15is adjacent to the first rail12A of the main track and the second end17is adjacent to the second rail12B of the main track12. The second transition rail14T2is positioned adjacent to an outside of the second rail12B of the main track and in longitudinal alignment with the second end17of the first transition rail14T1. The first transition rail14T1and second transition rail14T2are positioned over the installed turnout ties18A-18L.

Then, the method continues by installing the second curved rail14B in parallel alignment with the first and second transition rails14T1and14T2of the first curved rail14A adjacent to the outside of the second rail12B of the main track12. At least a portion of the turnout track14is attached to one or more of the installed turnout ties18A-18L under the parallel rails of the main track12and turnout track14. For example, as noted above, the rails12A,12B,14A, and/or14B can be seated within turnout plates20and/or attachment plates22provided on one or more of the installed turnout ties18A-18L. Force may be required for insertion of a rail into its plate.

Once the rails are seated in the plates20and/or22, the rails are clipped in place to the ties (e.g., using clips or fasteners or other mechanical devices, generally known in the art), as previously noted. Before clipping the rails14A and14B in place, the gap or clearance between the ends of rails of the turnout track14and sides of the rails of the main track12can be checked to ensure that the main track12can still be used. In an embodiment, the clearance between the rails is or should be at least approximately 5 inches.

After the rails14A and14B are installed and all rails12A,12B,14A, and14B are secured to their relative turnout ties18A-18L, then each rail transition device is installed and attached to predetermined ties of the installed turnout ties. This can include placement on and/or attachment of the attachment brackets28to their predetermined turnout ties18A-18L. Also, installation includes mounting the body portion60of each rail transition device over at least a portion of the turnout track such that the ramps66of the guide portion62are aligned with the rail, and removably connecting the leg portions30to the body portion60and to the predetermined ties of the installed turnout ties (if not already pre-connected). The horizontal portions32of each L-shaped bracket of each leg portion30is connected to one of the predetermined ties using attachment brackets28. The extension portion48of each attachment bracket28is inserted through each receiving opening52on the horizontal portion32, and each pin54is inserted through the slot50of the extension portion48. Each attachment bracket28is attached via bolts49to its predetermined tie.

Each rail transition device100,200,300, and400is capable of being removed and reinstalled using the pins54and attachment brackets28. The attachment brackets28can be installed to a turnout tie by securing bolts49through openings46of the attachment brackets28. The attachment brackets28can be bolted to ties before alignment with the body portion60, or bolted to ties after the body portion60is connected to the alignment bracket28(e.g., placing the extension portions48through openings52) to allow for movement and alignment of the rail transition devices before they are secured.

Installation may also include adjusting one or more rail transition devices in a vertical direction relative to the rails of the turnout track to a selected position, and securing or locking the adjusted rail transition devices in the selected position. If not already, the vertical portion34of each L-shaped bracket of each leg portion30is connected, or alternatively, further secured to the body portion60(e.g., after ramp alignment with the rail). Also, the elevation of the body portion can be adjusted in a vertical direction relative to the leg portions and the rails of the turnout track to a selected position using the adjustment slots36, and locked (e.g., via nuts40) in the selected position.

Again, color coding (or similar markings) can be used to ease installation of the rail transition devices. For example, the ramps66of each rail transition device100,200,300, and400may be marked or colored with different markings/colorings to match locations on the installed turnout ties18A-18L. The ramps of the guide portion62are aligned with the appropriate rail on the main track12and/or turnout track14such that the guard rail is positioned between the installed parallel rails of the turnout track.

It should be understood that any number of tools and equipment can be used to install the herein disclosed system as described above, including, but not limited to: a sledge hammer, a spike maul, a claw bar, a lining bar, a hydraulic impact, tape measure, backhoe, chain, spray paint or other marking medium (e.g., to mark areas or rails).

In addition to the features noted above, the herein disclosed portable and temporary system and its method of installation provides a low cost alternative to conventional turnout designs. The disclosed portable turnout system design allows for movement of rail equipment, e.g., switching of rolling stock, vehicles, or maintenance of way equipment) off a main line track or industrial lead at low speeds (e.g., equal to or less than approximately 10 mph) and requires no cutting or bending of the permanent main line track structure. It also is not installed over the rails of the main line, thereby substantially reducing and/or preventing damage and/or stress on the permanent main line rails. Further, electric and/or electronic equipment is not required to switch between use of the main track and the turnout track. Accordingly, equipment can move over, or leap over, the rails of the main line.

Further, the disclosed system provides the ability to install a turnout track in locations where there is not siding access. It is also more cost effective in that it reduces costs associated with installation (e.g., only a few workers or group is required for installation) and maintenance of the parts of the system.

The materials used form the parts of the system10are not meant to be limiting. In an embodiment, at least the ramps and guide portion are formed from steel, such as A36 steel. The materials and parts can be optionally heat treated and/or case hardened. Industry standards such as AISI Standard 1018 and 8620 and/or ASTM A108 may be used to form the parts of the rail transition devices100,200,300, and400, for example. Any of the parts of the rail transition devices (e.g., body portion60) may be repaired or replaced if damaged.

While the principles of the disclosure have been made clear in the illustrative embodiments set forth above, it will be apparent to those skilled in the art that various modifications may be made to the structure, arrangement, proportion, elements, materials, and components used in the practice of the disclosure. For example, it is envisioned that the leg portions30and body portion60need not be limited to the shapes shown in the Figures. Also, for example, the body portion60may not be adjustable in height. In one embodiment, the body portion60and leg portions30are formed integrally together as a single piece.

It will thus be seen that the features of this disclosure have been fully and effectively accomplished. It will be realized, however, that the foregoing preferred specific embodiments have been shown and described for the purpose of illustrating the functional and structural principles of this disclosure and are subject to change without departure from such principles. Therefore, this disclosure includes all modifications encompassed within the spirit and scope of the following claims.
