I, GEORGE ANDERSON, M.I.C.E., of Madras, in the Empire of India, District
Engineer to the District Board of Malabar, do hereby declare the nature of this
invention to be as follows:-
My invention relates to improvements in plant for laying permanent way.
It has hitherto been the practice, in this country, to lay the several part con-
stituting the permanent way, i.e., the sleepers, chairs, rails, and fish-plates, seriatim
upon the road-bed, and afterwards making each connection in turn.
Several proposals have been made, during the last decade, to economise the hand-
labour inseparable from the above described system of laying permanent way, by the
use of a construction-train adapted to travel forward upon the permanent way already
laid, and to carry a supply of the several parts,-sleepers, rails, and so forth, which
are then delivered, either seriatim or after being made up into lengths, at the head
of the train, and laid upon the road-hed. But considerable delay has always been
occasioned by the necessity of hauling the empty trucks of the construction-train
over the line back to the base of operations or to the nearest store of permanent-
way-material. It has, therefore, been impossible to keep up a constant supply of
material to the gang in front, for, it is evident that loaded trucks of material cannot
be carried forward over a line required for the transit of empty trucks in the opposite
direction.
In carrying my invention into effect, I provide a train of platform-trucks, upon
each of which pairs of transverse rails are laid and extended on to wings supported
on the sides of said trucks. Corresponding wings are formed upon the opposite
sides of the trucks. A traverser, and means for operating it upon each transverse
line, are provided; and across these traversers are laid rails parallel with the
permanent way; and which rails constitute the main line along which supplies are
brought to the front. Bogies upon said main line receive the lengths of rails to
which have been previously attached their complement of chairs, sleepers, fish-plates,
pins and bolts, or the equivalent thereof.
Suitable connecting pieces are provided between adjoining trucks and adjoining
wings to make the line from one truck to its neighbour, and the siding from one
wing to the adjoining one, respectively continuous.
As soon as the bogies in front have been emptied they are traversed on to the
siding and run back over the main line to the depot to be reloaded, while loaded
trucks are being pushed to the front along the main line on the trucks. The depôt

page_text: may be stationary, or there may be, in addition, a subsidiary one made up of a line
of trucks on a continuation of the main line.
In front of the line of trucks, and forming part of the train, is a double-bogie on
which is supported, by suitable framing and at a suitable height, a pivotted and
balanced cantilever projecting in front of the bogie over that part of the road-bed
immediately in front of the last-laid piece of permanent way.
Attached to the cantilever is an overhead carrier, which is continued from the front
end of the cantilever backwards over the material-loaded bogies before described. The
carrier is supported on frames springing from the trucks under said bogies; and the
several sections of the entire carrier are made continuous by suitable pivotal
connections.
The carrier consists, preferably, of two beams or girders; each furnished with a rail
supported on a bracket or web projecting from the side of the girder. The respective
rail ends are conected to the bracket by a bolt passing up through the latter into a
cavity in the rib of the rail. A certain play is allowed this bolt to facilitate the
passage of the carrier round a bend.
Hangers are provided adapted to run upon the carrier-rails, each terminating in a
pulley over which passes the chain of a gripper pendent therefrom. The chains of
all the grippers are led away to a winding drum. Each hanger-frame has, preferably
four travelling wheels, and is fitted with a guide-carriage at each end, which is flexibly
connected to it, for the purpose of taking the rails fairly as it is hauled along over
the joints thereof, when the train is on a curve. The connection between the banger-
frame and the cheeks of the gripper-pulley is pivotal.
The series of hangers and grippers is hauled along the carrier into position over
the loaded bogies; and the grippers are attached to the top pair of rails of the front,
or each, load. The rails are raised, their ends (if more than one pair is being
handled) connected, next moved forward to the front, i.e., to under the section of the
carrier attached to the cantilever, and then lowered on to the road-bed.
The train is then moved forward for a distance equal to the length of new line
just laid while, at the same time, another length can be hauled forward along the
carrier.
I sometimes employ two cantilevers of similar construction. The second one is
placed in front of the other; and is hauled along the road-bed, or carried by a traction-
engine, which is also connected to the construction-train by suitable hauling
devices. When two cantilevers are employed, the one in front of the other and
each with a continuous carrier; twice the length of line can, of course, be laid at
one operation.
.
The two cantilevers, with their respective sections of carrier, are made continuous
by suitable pivotted connections.
The traction engine may also be used where there is only one cantilever in the
train, especially when the curves are of short radius, as well as for working the
overhead carriers, and as an auxiliary engine generally. Any necessary winding
gear may be fitted upon it.
I provide a motor of special construction to push the construction train forward;
and with it, or the traction engine above mentioned, may be incorporated the
winding apparatus for operating the overhead carrier, or other part of the apparatus.
According to my invention, the boiler, or equivalent part of the motor according
to its construction, is fixed very low to allow of the main line on the trucks being
carried over it from the depôt to the front.
I do not confine myself to any particular method of moving the loaded or empty
material trucks. They may be either hauled by a winding engine or have an
independent motor appropriated to their service.

page_text: Improvements in Plant for Laying Permanent Way.
I, GEORGE ANDERSON, M. Inst. C.E., of Madras, in the Empire of India, District
Engineer to the District Board of Malabar, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to improvements in plant for laying permanent way (hereinafter
termed railway track), and is intended to expedite the laying of the track by preventing
the delays incidental to, and inseparable from, the methods at present in use, or proposed
to be used.
In the best plant hitherto constructed, or proposed to be used, for the purpose of
laying railway track, there has been provided only one line along which the track-
sections could be taken out to the front, to be there laid upon the road-bed. When
the trucks loaded with the track-sections have been emptied, they have been sent back
along the said one line to the depôt to be there reloaded; and, of course, whilst they
were being taken back to the depôt, no more track-material could be sent forward to
the front, for it is self-evident that loaded trucks of track-sections cannot be sent
forward over the track, at the time it is being used for the transit of empty trucks in
the opposite direction.
Now, according to my invention, the supply of track-sections, ready tied, spiked,
and fished, to the front, is not interfered with by the presence, or return, of empty
trucks, inasmuch as the emptics are sent back to the depôt along a siding; and are,
therefore, incapable of interfering with the transit of loaded trucks to the front for a
longer time than is occupied by the act of traversing said empties from the main track
on to the said siding.
It has hitherto been the practice to send the materials of the track to the front in
unconnected parts; i.e., so many rails and the corresponding quantity of ties, fish-
plates, and spikes, separate from each other, and to either drop them on to the road-
bed seriatim, or to fit up a single section of track upon the leading truck, run it out
along a cantilever, and lower it from there on to the road-bed.
Now according to my invention, I fit up the track-sections, by a track-section 1
mean a pair of rails with its complement of ties, fish-plates, and connections,-ready
for the road-bed before loading them on to the trucks; and upon these trucks I
construct a continuous overhead carrier to which any number of track sections, bolted
together by men on the trucks, can be hung, and then run out at one time to the front
past the track already laid, and laid in front thereof upon the road-bed. A second
number of sections is run out along the same carrier whilst the fish-bolts of the number
last laid are being bolted up by the front gang and the whole apparatus moved forward
thereover by suitable engine-power.
The operation of my track-laying plant is continuous, and always in uninterrupted
communication with the depôt from which supplies are drawn. A given quantity of

page_text: track can be laid by it more quickly, and with a smaller staff, than by any plant
hitherto introduced; and, moreover, a full equipment of workshop, hut, office, store,
and hospital accommodation, may form part and parcel of the plant, and be taken
along with it.
For grappling with the difficulties of organisation and circumstantial obstacles
incidental to the construction of a railway track through a new country where supplies
are not to be procured, my invention offers the most tangible advantages and is, in
respect of its mobility and completeness of organisation, unequalled for the
purpose of running a military line from one strategical position to another.
In this specification, I describe and illustrate the application of my invention to
the laying of railway track, the rails of which are flanged, and therefore spiked to the
ties or sleepers. But it is, of course, obvious that a track, the rails of which are
double headed and laid in chairs according to the method universal in this
country, could be laid by the improved plant which forms the subject of my
present invention, as easily as the particular type of track shewn in the drawings.
The said invention consists in
1st: A train of trucks constituting a construction-train, adapted to travel forward
along the laid track, and having a main track laid upon it, over which bogies loaded
with track-sections are sent to the front, with which train is combined a set of
traversers leading to a continous siding-track constructed along the side of said trucks,
and over which the empty bogies can be run back to the depôt for the purpose of being
reloaded.
:
2nd An overhead carrier constructed upon said trucks, the bogies of which carrier
are each fitted with a suitable hanger and gripper for carrying forward the track-
sections.
3rd: A balanced cantilever swivelling upon a truck, or upon a locomotive, at the
head of the aforesaid train and attached thereto, and along which the overhead carrier
is continued.
4th: A balanced cantilever swivelling upon a truck or upon a locomotive, and along
which the overhead carrier is continued, and which is adapted to be hauled along the
road-bed in front of the first mentioned cantilever at a distance therefrom, and to be
attached thereto by hauling chains.
5th A propelling engine of special construction to allow the main track of the
construction train being carried over the same at the level of the said main track, and
with which is combined suitable winding machinery for working the overhead carriers
and traversers.
6th: In combination with the preceeding, a transport train for the purpose of
bringing up supplies of track-material from the depôt to the construction-train, and of
carrying the empty bogies back to the depôt to be reloaded.
I attain the several objects of my invention by means of the mechanisms illustrated
in the following drawings, in which
Fig. 1 is a general view, in side elevation, of the principal parts of my
invention.
Fig. 2 is a plan shewing the apparatus illustrated in Fig. 1. working round a bend
in the road-bed.
Fig. 3 is a side elevation of part of the cantilever on its bogie, two loaded track-
section bogies on the front truck of the construction train, and as much of the over-
head carrier as the figure includes.

well as the track-section bogies from the right hand truck, and including the second
wings, Q.
Fig. 7 is an end elevation of the truck of the construction train of Fig. 3.

and the continuation of the track over one truck to that over the next.
Fig. 11. is a side elevation; and
Fig. 12, a plan of a carrier-bogie.
Fig. 13 is a side elevation; and
Fig. 14 an end elevation, of the special type of locomotive adapted for the purpose
of propelling, or hauling, and generally working the construction-train.
Referring to Figs. 1 and 2, A is the road-bed; and B, the laid track.
C is a
traction-engine; D, the front cantilever; E, its truck; F, a hauling chain from the
front cantilever to the truck, G, of H, the cantilever at the head of the construction-
train.
I, I are two trucks of the construction train; J, the main track laid thereupon;
K, the siding-platform; L, the traversers; M, the bogies loaded with track-sections, N,
tied, spiked, and fished, ready for laying and O, the superstructures carrying the
overhead carrier, P. Q, Q are lateral extensions of the platforms of the trucks, I, on
the sides opposite to the sidings, K.
The traction engine, C, is of any suitable construction, and may conveniently be
furnished with a winding gear for operating the overhead carrier, P.
The cantilever truck, E, is of any suitable construction, its wheels however being
adapted to travel upon the road-bed, A. Both cantilevers, D and A, are made to swivel
upon their respective centres (see Figs. 3 and 4), for the purpose of allowing them to
adapt themselves to the radius of a curve.
I do not confine myself to the two cantilevers, as illustrated in Figs. 1 and 2, but
may use only one, viz.; that at the head of the construction-train. The advantage of
using two cantilevers as shewn is that a much longer length of track can be hauled
out of the construction-train and laid at one operation than if only one cantilever,
viz.; that at the head of said train, were in use. When only short lengths of track-
say not more than three or four 21 or 24 ft. lengths of rail-sections-are to be laid at
one operation, the cantilever, D, and its truck, E, are dispensed with, and the traction
engine, C, connected to the cantilever-truck, G.
Any suitable flexible connection may be introduced at the point to connect the two
cantilevers.
Referring to Figs. 3 and 4, a cantilever consists, preferably, of a pair of parallel
beams, or girders, h, h, adapted in any convenient way to swivel in a horizontal plane
above the top of the truck, G, upon a pivot fixed, preferably, at the centre thereof.
The rear end is weighted with a counterpoise for the purpose of balancing the canti-
lever upon the said pivot. In Fig. 3 the pivot is shewn in dotted lines as a downward
continuation, , of the centre post, h², and resting in a step bearing, h³, upon the
truck. The centre post, 2, terminates in a head, ', in which meet the fore
and aft braces, 73, Struts, 1, together forming an upward extension of the truck,
are provided for the purpose of maintaining the perpendicularity of the centre
post,
At equal intervals along the fore part of the cantilever, are fixed crossbeams, or
girders, ', from which depend pairs of hangers, hs, supporting the fore part of the
track of the overhead carrier. The construction of this overhead carrier and its
hangers is described in detail further on with reference to Figs. 7, 8 and 9. The
hangers, ³, are however necessarily longer than those illustrated in the figures
last mentioned and marked therein, to compensate for the height of the cantilever.
The construction-train may consist of any number of trucks, but this number,
assuming that each truck is as long as a track-section, is equal to the number of
sections that can be laid from one or from both cantilevers at one operation. Although
Figs. 1 and 2 show the construction-train as consisting of only two trucks, and the
cantilever-trucks within a corresponding distance of each other, I wish it to be distinctly
understood aht my invention is not limited likewise, inasmuch as the construction-

page_text: train may consist of as many trucks as the cantilever or cantilevers have stability to
bear lengths of rail-sections suspended from them.
Referring to Figs. 3, 5, 6 and 7, a truck of the construction-train consists of a
platform, i, upon bogies, or ordinary car wheels; two wings, k, Q, which are lateral
continuations of the platform, and are fixed thereto in any convenient way; a super-
structure (marked O in Figs. 1 and 2) consisting of pairs of posts, a, and braces, b,
longitudinal ties, c, cross pieces, d, and diagonal ties, d', to support the overhead
carrier; two transverse tracks, e, which are continued on to the wings, k; traversers, L,
adapted to run thereon; and part of the main-track, (J in Fig. 1), consisting of two
rails, g. The transverse tracks, e, are laid immediately upon the platform, ; the
traversers, L, occupy the next level, and the main-track, g, is laid on the next level
above, and partially upon, the traversers.
Rails, g, are laid upon the wing, k, to the same gauge as the rails, g, of the main-
track, J, and these, when the traversers, L, are moved outwards on to said wings, as
indicated by the dotted lines on the right hand corner of Fig. 6, constitute with
the rails, g, of the main track upon said traversers, a siding-track, the function of
which will be described at length further on.
The wings may be hinged to the platform i, and the braces, b, pivotted, so that
they may be folded up to let the train pass through a tunnel, as indicated in
Fig. 14.
The opposite wing, Q, may be furnished with a second siding, or there may be
constructed upon it workshops, stores, cabins, a hospital, or whatever may be con-
venient, or useful, to the management or staff. It is evident that to utilize the
wing, Q, for some purpose which will load it, will increase the stability of the
truck.
I provide bridge-pieces g², g³, for the main-track and siding-track, respectively,
to make them continuous with those on the adjoining trucks. These pieces are not
rigidly attached to the platform of the trucks, but loosely, as by means of studs, g',
and slots, g, to admit of the necessary degree of play between the trucks, especially
when the construction-train is moving round a curve.
M, M are bogies upon which the track-sections, N, previously fished, spiked, and
tied, are carried. The figures shew two bogies as carrying a load of track-sections, but
this number may be increased if necessary.
Two removable posts, u, fitting into sockets in the bogie-tops, ul, are furnished to
each track-section bogie. They are separated by a distance equal to the outside
width of two rails, and therefore always keep the sections centrally upon said
bogic-tops.
The overhead carrier, P, extends from the rear of the construction-train to the nose
of the cantilever in front thereof; and consists of track, hangers, bogies adapted to
run on said track, and grippers. The front cantilever is likewise fitted with it.
Referring to Figs. 3, 4, 5, 7, 8, 9 and 10, j, j, are a pair of rails constituting the
carrier-track. They are bolted to pairs of brackets, ', which are extensions of
hangers, 1, supported by the superstructures, O, over the trucks of the construction-
train, and to similar hangers, 78, on the projecting arms of the cantilevers.
The carrier-track over one truck is made continuous with that over the next truck
by means of short rails, or bridge-pieces, o, which are loosely and pivotally connected
to the brackets,, for the purpose of allowing them a certain degree of play, or
motion backwards and forwards.
The function of these pivotal connections is to make the carrier-track sufficiently
flexible to enable it to adapt itself to the curves of the track, B, as the entire plant is
moved along them. Further pivotal connections of the same, or similar, construction
are introduced into the portion of the carrier-track on the cantilever-truck, G, as
indicated at o², Fig. 3.
To effect a pivotal connection adapted to satisfy the said requirements, I form a
slot, m, near the end of each bridge-piece, o, in the web thereof. The slots are long
enough to prevent their either pulling on, or pushing at, the bolts, n, by which they
are held upon the brackets, ; and are deep enough to permit of the nut, washer, and

page_text: bolt, being screwed up after the latter has been passed through the bracket and the
rail-foot.
The construction of the bogies adapted to run upon the rails of the overhead
carrier-track, and to carry the track-section suspended therefrom, is illustrated in
detail in Figs. S, 11 and 12.
R is the frame of the bogie; and r,, its travelling wheels. Smaller wheels, r¹‚—
one pair in front of, and a second pair behind, the bogie-are provided; and each
pair is pivotally connected to the frame, R, of the bogie at, The function of
these pairs of small wheels at each end of the bogie is to guide the latter safely over
the bridge-pieces, o, o, when the construction-train is standing on a bend. This they
are enabled to do in virtue of their being smaller in diameter than the travelling
wheels, r, and, therefore, less liable to be jerked off the rails, and also because of
their connections, 2, with the bogie frame, R, being pivotal.
Each carrier-bogie has a grooved pulley, s, pivotted to it by means of a bolt, s,
passing up vertically through the head of the pulley-loop, s2, and through the central
part of the bogie-frame, R. The hole, s³, in the head of the pulley-loop is, preferably,
widened laterally at the bottom, as shewn by dotted lines in Fig. 8, for the purpose
of allowing the pulleys to swing laterally when the grippers, t, are loaded with a
rail-section, and being hauled along the carrier-track, j
A chain, t, terminating in an automatic gripper, t, passes over each pulley, s, from
which it is led away to a suitable winding apparatus adapted to raise or lower the
gripper, and haul the carrier-bogie in either direction along the carrier-track, j..
There are several ways in which the chains, t, can be operated by the winding
apparatus. I do not lay claim to, neither do I confine myself to, any one in particular.
They may be led away rearwards as indicated in Figs. 1, 3, and 5, to a winding drum
on the locomotive behind the construction-train and chains fixed to the bogie-
frames, R, may be led away to a winding apparatus upon the traction-engine, C.
I provide a locomotive at the rear of the construction-train to run upon the laid
track, B, and to push said train and cantilever at the head of it along the said track
as the latter is laid. When iwo cantilevers are used with the traction engine, C, then
the latter will assist the locomotive in moving the construction-train forward.
Upon either or both traction engine and locomotive, I provide a suitable winding gear
for working the chains, t, of the overhead carrier in the manner hereafter described.
I may, if desirable, equip the locomotive with the necessary winding gear for
working the bogie-carriers and chains, t, in both directions, also for effecting the
transit of the loaded bogies, M, from the transport-train on to the construction-train
and, shunting the empty bogies from the construction-train on to the transport-train
again.
The aforesaid locomotive may be driven either by steam, by electricity, or by any
other agency.
Whatever type of engine be made use of, the space occupied by the
boiler in the present steam locomotive must be left clear for a length of track of the
same gauge and fixed in the same plane as the main track, g, on the trucks, I, of
the construction-train.
Consequently, the boilers (if the engine be driven by steam) must be beneath or at
the side of the frame. I prefer that they should be placed as low down as possible
for the purpose of increasing the stability of the locomotive. The usual gear will be
distributed accordingly. If an electric motor be used, it would be constructed on the
same principle, namely so as to carry a track of the same gauge as the track, I at
the same level as, and continuous with, it.
This special construction of locomotive is illustrated in Figs. 13 and 14 as embodied
in a steam engine. The platform, i, and the wings, and Q, are of the same con-
struction and carried on the locomotive at the same height as those before described.
W is a water tank on the steam boiler; x, the cab; and the cylinders.
Y: Y,
Behind the said engine and upon the laid track is a transport-train for the
conveyance of loads of track-material from the depôt to the construction-train.
A truck of the transport train consists, referring to figures 5 and 6, of platform, i,
upon bogies or ordinary car wheels, and main track, g.

page_text: My invention is operated as follows.
For
The transport-train carrying pairs of bogies, M, each pair having the same number
of track-sections (seven is a convenient number) ready tied, spiked and fished, loaded
on to them, the bottom truck-sections resting preferably on the bogic tops, u, as
illustrated, is brought up from the depôt to the locomotive of the construction-train,
and the loaded bogies, M, run along the track, g, onto the construction-train.
the purpose of effecting this transit of the loaded bogies, M, from the transport-train
on to the construction-train, I use either a small locomotive adapted to run upon the
track on the transport-train and to push the loaded bogies forward onto the con-
struction-train into the position illustrated in Figs. 3, 5, 6 and 7, or I furnish the
locomotive of the construction-train with a suitable hauling gear for effecting said
transit.
The loads of track-sections, N, being now upon the construction-train and under
the overhead carrier, P, the next step is to lift and haul forward the top section, N, of
each load.
For this purpose a gang of operatives upon the construction-train engages the
grippers with the ties respectively under them, and the chains, t, are hauled in for
the purpose of lifting the top layer of sections from all the loads on the construction-
train at once.
While they are swinging in the air, the adjacent ends of the several
sections are loosely connected by the fish-plates and bolts, and the carrier-bogies
hauled out along the cantilever immediately over the road bed in front of the cantilever-
truck, G. The suspended sections (shewn in dotted lines in Fig. 1) are then lowered
on to the road bed, A, and the several fish-plates bolted up. If the track is being laid
upon a bend in the road-bed, the cantilevers are swung on their pivots, ¹, and
the suspended track-sections accordingly made to follow the bend as they are
lowered.
Immediately the ties or sleepers of the several sections are on the road-bed, the
grippers, t, are released, the chains, t, hauled in, and the carrier-bogies run back
along the carrier-track, j, until they are in their former position, i. e., over the second
tier of rail-sections.
Meanwhile the construction-train has been moved forward over the new track laid
at the last operation. The grippers, t, are again engaged, this time with the ties of
the second tier of sections respectively underneath them. These are raised, loosely
connected together, hauled out to the front, lowered on to the road-bed, and bolted up
as before.
The above described series of operations is repeated until the seventh, or bottom,
tier of sections has been hauled from off the bogies, M.
The bogies are then traversed by means of the traversers, L, onto the wings, k, and
moved back along the siding to the rear of the construction-train, whereupon the
traversers are moved back so as to again make the main track, y, continuous for the
transit to the front of the next train of loaded bogics from the transport train along
said track. The empty bogies can then be shunted onto the transport-train and taken
away to the depôt to be reloaded, while the train of loaded bogies last brought up on
the transport-train from the depôt are being sent forwards onto the construction-
train.
To facilitate the work of traversing the empty bogies from off the siding-track, g',
on to the track of the transport-train, I may interpose a truck with main track, siding,
and traversers, between the construction-train and its locomotive.
A second siding-track may be laid upon the wings, Q, the traversers being made
duplex as indicated by the dotted lines, LA, in Fig. 6. By this means the passage of
the traversers from the main track, g, to the siding-track, g', would make both track
and siding continuous at once, so that fresh loads of track-sections could be brought
onto the construction-train without waiting for the transit of the empty bogies off the
traversers in the siding-track, g', and the return of said traversers to the main
track.
The transport-train and the locomotive above described may, if desired, be fitted
with sidings, as the construction-train.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. In a track-laying plant, the combination of a construction-train adapted for the
transit therealong of loads of track-sections; an overhead carrier supported above
and along the construction-train; a siding-track for the return of the empty track-
section bogies; traversers adapted to effect the traverse of the track-section bogies between
the main track and the said siding; engines adapted to move the construction-train
forward, and to operate the overhead carrier on their respective tracks; and suitable
winding or other gear for operating the various members of the construction-train
and overhead carrier.
2. The combination with the truck of a construction-train, of a wing, or lateral
continuation of the truck-platform, on each side thereof, one or both of said wings or
lateral extensions adapted to receive a siding-track; substantially as and for the
purpose set forth.
3. The combination with the truck of a construction-train, of a wing or lateral
continuation of the truck-platform on each side thereof, one (or both) of said wings or
lateral extensions adapted to receive a siding-track, and the other to be fitted as a
workshop, store, or cabin; substantially as described.
4. The combination with the truck of a construction-train, of traversers adapted to
run upon rails laid transversely upon the platform of said truck and upon a wing, or
lateral extension, of said platform, upon which traversers are laid sections of the
main track of the construction-train, and which sections are adapted to make
continuations with either a siding-track of the same gauge as the main track laid
upon the wing or lateral extension, or with the main track upon the platform according
to the position of the traversers.
5. The combination with the trucks of a construction-train having a track secured
to the platform thereof, and a siding track to the siding-platform thereof, of bridge
pieces alsovided with tracks pivotally connected to the said platforms, respectively,
and thereby adapted to make continuous the respective tracks on one truck of the
construction-train with those on the adjacent trucks, substantially as and for the
purpose set forth.
