The AAR wheel arrangement system is a method of classifying locomotive ( or unit ) wheel arrangements that was developed by the Association of American Railroads . It is essentially a simplification of the European UIC classification , and it is widely used in North America to describe diesel and electric locomotives . It is not used for steam locomotives which use the Whyte notation instead . The AAR system counts axles instead of wheels . Letters refer to powered axles , and numbers to unpowered ( or idler ) axles . A refers to one powered axle , B to two powered axles in a row , C to three powered axles in a row , and D to four powered axles in a row . 1 refers to one idler axle , and 2 to two idler axles in a row . A dash ( - ) separates trucks , or wheel assemblies . A plus sign ( + ) refers to articulation , either by connecting bogies with span bolsters or by connecting individual locomotives via solid drawbars instead of couplers .
In engineering , a prime mover is an engine that converts fuel to useful work . In locomotives , the prime mover is thus the source of power for its propulsion . In an engine-generator set , the engine is the prime mover , as distinct from the generator .
The Beep ( also referred to as the SWBLW ) is an individual switcher locomotive built in 1970 by the Atchison , Topeka and Santa Fe Railway at its Cleburne , Texas , workshops . Technically a rebuild , the Beep ( a portmanteau of Baldwin Geep , whose official designation was derived from SWitcher , Baldwin Locomotive Works ) originally entered service on the Santa Fe as a Baldwin Model VO-1000 . Following its successful CF7 capital rebuilding program , the company hoped to determine if remanufacturing its aging , non-EMD end cab switchers by fitting them with new EMD prime movers was an economically viable proposition . The conversion procedure proved too costly and only the one unit was modified . As of end of 2008 per Trains Magazine March 2009 , this locomotive was retired and stored operational at Topeka , Kansas . In May 2009 the unit was donated to the Western America Railroad Museum in Barstow , California .
The EMD 567 is a line of large medium-speed diesel engines built by General Motors ' Electro-Motive Division . This engine , which succeeded Winton 's 201A , was used in EMD 's locomotives from 1938 until its replacement in 1966 by the EMD 645 . It has a bore of 8 1⁄2 in ( 216 mm ) , a stroke of 10 in ( 254 mm ) and a displacement of 567 cu in ( 9.29 L ) per cylinder . Like the Winton 201A , the EMD 645 and the EMD 710 , the EMD 567 is a two-stroke engine . EMD 's chief competitor , GE , now makes EMD-compatible replacement parts .
The CF7 is an EMD F-unit railroad locomotive that has had its streamlined carbody removed and replaced with a custom-made , general purpose body in order to adapt the unit for switching duty . All of the conversions were performed by the Atchison , Topeka and Santa Fe Railway in their Cleburne , Texas workshops between October , 1970 and March , 1978 . The program was initiated in response to a system-wide need for more than 200 additional four-axle diesel road switchers to meet projected motive power demands on branch lines and secondary main lines . Santa Fe 's aging fleet of 200-series F-units were in dire need of overhaul , and were not suitable for switching service in their original configuration due to the poor visibility resulting from their full-width carbody ; the engineer was required to stick their head out of the window in order to see the end of the train or locomotive when coupling and uncoupling cars . As new , state-of-the-art locomotives cost upwards of $ 150,000 each at the time , Santa Fe elected to experiment with modifying its existing F-units to serve their purpose , which they hoped they could accomplish for around $ 60,000 each . Changes in business philosophy led the company to sell off its entire CF7 inventory by 1987 , with most of the units ( all but nine ) ending up in the hands of regional and short-line railroads , and a few excursion lines . A number remain in service today . [ vague ]
A GP8 is a four-axle road switcher diesel locomotive rebuilt by Illinois Central 's Paducah shops using a General Motors Electro-Motive Division ( EMD ) GP7 , GMD GP7 or GP9 as a start . It is similar to the GP10 and GP11 . A total of 111 units were rebuilt to GP8 for the Illinois Central and Illinois Central Gulf . Core units used in the construction of these units were Illinois Central GP7 , GP9 , a GP8 , C & O GP9 , D & RGW GP9 , DT & I GP7 , N & W GP7 , P & LE GP7 , QNS & L GP7 , RDG GP7 , St.J & LC GP9 , SLSF GP7 , and SP GP9 . The Paducah Shops also rebuilt 16 Conrail GP7s to GP8s . Nine were rebuilt in 1976 and another seven in 1978 . Rock Island 's Silvis Shops rebuilt 20 Conrail GP7s into GP8s in 1978 . Morrison-Knudsen 's Boise Shops rebuilt 13 Conrail GP7s into GP8s in 1978 . The 1976 Conrail units rebuilt at Paducah were the equivalent of the Illinois Central rebuilds . The 1978 rebuilds were engine and electrical gear only rebuilds with no carbody modifications .
The EMD GP10 is a road switcher diesel-electric locomotive that is the result of rebuilding a GP7 , GP9 or GP18 . The Illinois Central Railroad had three separate rebuild programs to upgrade their old EMD GPs and GPs that they had purchased from equipment dealers such as Precision National Corporation in Mount Vernon , Illinois . The first was the GP8 , second the GP10 and third the GP11 . All were rebuilt at IC/ICG 's Paducah Shops in Kentucky . Core units for the GP10 program were from IC/ICG GP7 , GP8 , GP9 and GP18 , B & M GP9 , B & O GP9 , CRR GP9 , C & O GP7 and GP9 , D & RGW GP9 , DT & I GP7 and GP9 , FEC GP9 , GTW GP18 , P & LE GP7 , Potlach Forests Inc. GP7 , QNS & L GP9 , RDG GP7 , St.J & LC GP9 , SLSF GP7 , SP GP9 , SSW GP7 , and UP GP9B . Two IC GP9s were rebuilt to GP10s and sold directly to the Ashley , Drew and Northern Railway . Nine Alaska Railroad GP7s were rebuilt to GP10s by Paducah , and renumbered 1801-1809 ( these rebuilds received EMD angled cabs but kept their AAR Type B road trucks from Alco RS-1s ) . A total of 76 Conrail GP9s were rebuilt to GP10s . The Paducah Shops rebuilt 53 Conrail GP9s to GP10s . The first 16 Conrail GP9s were rebuilt to the equivalent of a GP10 in 1976 . In 1978 another 21 Conrail GP9s were rebuilt at Paducah , followed by 16 more GP9s rebuilt to GP10 in 1979 . The 1978-79 Conrail GP9 rebuilding program by Paducah was engine and electrical gear only with no carbody modification ( the high short hoods were kept ) .
The EMD GP11 is a four-axle road switcher diesel locomotive rebuilt by the Illinois Central Railroad 's Paducah shops . It is very similar in appearance to the GP8 and GP10 . The Illinois Central Railroad began its GP11 rebuilding program in 1978 . All units were rebuilt from recycled EMD GP7 , GP9 or GP18 parts . Spotting features are an angled cab , exterior paper air filter , new air intake for the traction motors and four exhaust stacks . Internally they had Dash 2 solid state electrical equipment .
An EMD GP9 is a four-axle road switcher diesel-electric locomotive built by General Motors ' Electro-Motive Division produced between 1954 and 1959 and it is powered by a sixteen-cylinder engine which generated 1,750 horsepower ( 1.30 MW ) . The GP9 succeeded the GP7 . The lettering GP stands for general purpose . This locomotive type was offered both with and without control cabs ; locomotives built without control cabs were called GP9B locomotives .
Caterpillar Inc. ( sometimes shortened to CAT ) is an American Fortune 100 corporation which designs , develops , engineers , manufactures , markets and sells machinery , engines , financial products and insurance to customers via a worldwide dealer network . It is the world 's largest construction equipment manufacturer . In 2018 , Caterpillar was ranked # 65 on the Fortune 500 list and # 238 on the Global Fortune 500 list . Caterpillar stock is a component of the Dow Jones Industrial Average . Caterpillar Inc. traces its origins to the 1925 merger of the Holt Manufacturing Company and the C. L. Best Tractor Company , creating a new entity , the California-based Caterpillar Tractor Company . In 1986 , the company reorganized itself as a Delaware corporation under the current name , Caterpillar Inc. Caterpillar 's headquarters are located in Deerfield , Illinois ; it announced in January 2017 that over the course of that year it would relocate its headquarters from Peoria , Illinois , to Deerfield , Illinois , scrapping plans from 2015 of building an $ 800 million new headquarters complex in downtown Peoria . The company also licenses and markets a line of clothing and workwear boots under its Cat / Caterpillar name . Caterpillar machinery is recognizable by its trademark Caterpillar Yellow livery and the CAT logo .
The EMD GP16 was a series of rebuilt road switcher diesel-electric locomotives , a result of a remanufacturing program initiated by the Seaboard Coast Line Railroad ( SCL ) in an effort to spare the cost of purchasing new motive power in the late 1970s . This involved the rebuilding of their aging fleet of EMD GP7 , GP9 , and GP18 road switchers ( many of which were over twenty years old ) . 155 locomotives ( 122 GP7 , 31 GP9 and two GP18 ) were rebuilt by the SCL .
The EMD 645 family of diesel engines was designed and manufactured by the Electro-Motive Division of General Motors . While the 645 series was intended primarily for locomotive , marine and stationary engine use , one 16-cylinder version powered the 33-19 Titan prototype haul truck designed by GM 's Terex division . The 645 series was an evolution of the earlier 567 series and a precursor to the later 710 series . First introduced in 1965 , the EMD 645 series remained in production on a by-request basis long after it was replaced by the 710 , and most 645 service parts are still in production . The EMD 645 engine series is currently supported by Electro-Motive Diesel , Inc. , which purchased the assets of the Electro-Motive Division from General Motors in 2005 . In 1951 , E. W. Kettering wrote a paper for the ASME entitled , History and Development of the 567 Series General Motors Locomotive Engine , which goes into great detail about the technical obstacles that were encountered during the development of the 567 engine . These same considerations apply to the 645 and 710 , as these engines were a logical extension of the 567C , by applying a cylinder bore increase , 645 , and a cylinder bore increase and a stroke increase , 710 , to achieve a greater power output , without changing the external size of the engines , or their weight , thereby achieving significant improvements in horsepower per unit volume and horsepower per unit weight .
The New Zealand DB class and DBR class locomotive is a type of diesel-electric locomotive built for service on New Zealand 's rail network . They were built by General Motors Diesel ( GMD ) of Canada as a narrow-gauge version of the EMD G8 model , with seventeen locomotives constructed . Ten of these were later rebuilt into the DBR class .
The New Zealand DC class is a class of diesel-electric mainline locomotive on the New Zealand rail network , operated by KiwiRail on freight trains , and formerly on long-distance KiwiRail Scenic passenger trains . The class was rebuilt from the DA class in the late 1970s and early 1980s , mainly in Australia . After the DA class they were the most numerous class of diesel locomotive on New Zealand 's railway network , and remained numerically dominant until the mid-2010s when withdrawals began .
The DQ and QR class were a class of diesel locomotives in New Zealand and Tasmania , Australia . Originally built by Clyde Engineering in the 1960s as Queensland Rail 1460 and 1502 class locomotives , they were purchased by Tranz Rail in 1995 to be rebuilt , as a cheaper alternative to buying new locomotives .
The EMD GP30 is a 2,250 hp ( 1,680 kW ) four-axle road switcher diesel-electric locomotive built by General Motors Electro-Motive Division of La Grange , Illinois between July 1961 and November 1963 . A total of 948 units were built for railroads in the United States and Canada ( 2 only ) , including 40 cabless B units for the Union Pacific Railroad . It was the first so-called second generation EMD diesel locomotive , and was produced in response to increased competition by a new entrant , General Electric 's U25B , which was released roughly at the same time as the GP30 . The GP30 is easily recognizable due to its high profile and stepped cab roof , unique among American locomotives . A number are still in service today in original or rebuilt form .
The passenger locomotives derivatives of the General Motors EMD GP40 diesel-electric road switcher locomotive have been , and continue to be , used by multiple passenger railroads in North America . For passenger service , the locomotives required extra components for providing steam or head-end power ( HEP ) for heating , lighting and electricity in passenger cars . Most of these passenger locomotives were rebuilt from older freight locomotives , while some were built as brand new models .
In rail transport , head-end power ( HEP ) , also known as electric train supply ( ETS ) , is the electrical power distribution system on a passenger train . The power source , usually a locomotive ( or a generator car ) at the front or 'head ' of a train , provides the electricity used for heating , lighting , electrical and other 'hotel ' needs . The maritime equivalent is hotel electric power . A successful attempt by the London , Brighton and South Coast Railway in October 1881 to light the passenger cars between London and Brighton heralded the beginning of using electricity to light trains in the world .
