trains, and those to or from the main UP trains walk across the 

 footbridge or subway to get to the opposite platform. 



Fig. 378 is a plan of a double -line roadside station, with two 

 main-line passenger platforms and a dock line and platform for 

 the use of local or branch-line trains. This arrangement is 

 applicable where the actual junction with the main line is at a 

 little distance from the station, but not sufficiently far away to 

 warrant an additional junction station as shown in Fig. 377. 



Fig. 379 shows a similar roadside station laid out with a 

 more comprehensive arrangement of dock-lines and platforms. 

 The lines alongside the main passenger platforms are turn-outs 

 from the main-line proper, and leave the latter free for the 

 passage of fast through trains or goods trains when an ordinary 

 passenger train is standing alongside the platform. In this way 

 a fast non-stopping train can overtake and be sent forward in 

 advance of a slow passenger train. 



Fig. 380 shows a roadside station with two double platforms, 

 the inner lines and platforms being reserved for main-line 

 passenger trains, and the outer lines for branch-line trains. By 

 this arrangement carriages can be quickly transferred from a 

 branch-line train to a main-line train, and vice versa ; access 

 from the public road, or from one platform to the other, can be 

 obtained either by subway or over-line footbridge. 



Fig. 381 is a sketch plan of an island platform for a double- 

 line roadside station, near which there are junctions with two 

 branch lines. The UP and DOWN main lines run alongside 

 the wide portion of the platform, and the branch lines run into 

 the two dock platforms. The waiting-rooms, refreshment- 

 rooms, etc., are placed in groups on the wide platform, spaces 

 being left between the blocks for the convenience of access from 

 side to side. The booking-office and parcels- office are placed 

 alongside the approach road on the higher level. An over-line 

 footbridge extends from the booking-hall to the dock platforms, 

 terminating with steps on one side and an inclined ramp of 1 in 

 8 on the other. In carrying out the above plan for a railway 

 on an embankment, the access from the booking-hall to the 

 platform would be provided by a subway instead of an over-line 

 footbridge. 



Fig. 382 shows another form of island platform, also arranged 

 for UP and DOWN main-line trains, and two branch-line 

 trains. The access is obtained from a public-road over-line
