outgoing as well as incoming trains. The lengths of the main- 

 line or local platforms will be regulated by the number of 

 carriages forming a train. 



Fig. 373 is a diagram sketch of a large terminal passenger 

 station, with main and local platforms as above described. It is 

 merely typical to illustrate the principle, and may be multiplied 

 and varied to any extent in the way of lines and platforms. In 

 the sketch the main groups of offices, waiting-rooms, etc., are 

 shown at the end of the station ; but they may be equally well 

 placed at the side, as their actual location is principally a question 

 of proximity or convenience of access to some main street or 

 thoroughfare. The lower or platform-level rooms of such a 

 building are mainly devoted to the public for booking-offices, 

 waiting-rooms, refreshment-rooms, lavatories, offices for parcels, 

 telegraph and inquiry, suitable rooms being set apart for lamps, 

 foot-warmers, guards, and porters, Above this lower story a 

 range of offices can be built for the use of the principal officers 

 and staff of the different departments of the company. 



Fig. 374 is a plan of a small terminal station on a single line 

 of railway, where the passenger traffic is small, and one platform 

 is made to serve alternately both for arrival and departure 

 trains. The booking-hall, waiting-rooms, offices, etc., are laid 

 down parallel to the line of rails, and the approach road and 

 footpath are parallel to the building. The platform roof extends 

 to the outer wall, and provides shelter for the passengers on the 

 platform, and forms a shed for the carriages at night. 



Fig. 375 is a sketch of an intermediate or roadside station 

 on a single line of railway. All the offices, waiting-rooms, etc., 

 are on one platform, which serves for trains travelling in either 

 direction. The dotted lines show the additions which would be 

 necessary to make the station a stopping-place for trains working 

 in opposite directions. 



Fig. 376 shows an ordinary intermediate or roadside station 

 on a double line of railway, with two passenger platforms, and a 

 connection between them either by subway or over-line foot- 

 bridge. The principal offices and waiting-rooms are shown on 

 the one side, and only small waiting-rooms, etc., on the other. 



Fig. 377 is a sketch of a double-line intermediate or roadside 

 station at the junction of a small single-line branch railway. 

 Branch-line passengers to and from the main DOWN-line trains 

 merely walk across the platform to get into their respective
