24 RAILWAY CONSTRUCTION. 



Home or starting signals next in advance of trailing-points 

 when lowered, to lock such points in either position, unless such 

 locking will unduly interfere with the traffic. 



A distant signal must not be capable of being lowered unless 

 the home and starting signals in advance of it have been 

 lowered. 



8. Sidings to be so arranged that shunting operations upon 

 them shall cause the least possible obstruction to the passenger 

 lines. Safety-points to be provided upon goods and mineral 

 lines and sidings, at their junctions with passenger lines, with 

 the points closed against the passenger lines and interlocked 

 with the signals. 



9. When a junction is situated near to a passenger station, 

 the platforms to be so arranged as to prevent, as far as possible, 

 any necessity for standing trains on the junction. 



10. The junctions of all single lines to be, as a rule, formed 

 as double-line junctions. 



11. The lines of railway leading to the passenger platforms to 

 be arranged so that the engines shall always be in front of the 

 passenger trains as they arrive at and depart from a station ; 

 and so that, in the case of double lines, or of passing places on 

 single lines, each line shall have its own platform. At terminal 

 stations a double line of railway must not end as a single line. 



12. Platforms to be continuous, and not less than 6 feet 

 wide for stations of small traffic, nor less than 12 feet wide for 

 important stations. The descents at the ends of the platforms 

 to be by ramps, and not by steps. Pillars for the support of 

 roofs and other fixed works not to be less than 6 feet from the 

 edges of the platforms. The height of the platforms above rail 

 level to be 3 feet, save under exceptional circumstances, and in 

 no case less than 2 feet 6 inches. The edges of the platforms to 

 overhang not less than 12 inches. As little space as possible 

 to be left between the edges of the platforms and those of the 

 footboards on the carriages. Shelter to be provided on every 

 platform, and conveniences where necessary. Names of stations 

 to be shown on boards and on the platform lamps. 



13. When stations are placed on, or near a viaduct, or bridge 

 under the railway, a parapet or fence on each side to be pro- 

 vided of sufficient height to prevent passengers, who may by 

 mistake leave the carriages when not at the platform, from 

 falling from the viaduct or bridge in the dark.
