Station Platforms

Station platforms are provided for the entraining and detraining of passengers. Platforms can be rail-level, low-level, or high-level platforms depending upon the expected passenger traffic at each station. The general policy of Indian Railways is to provide high-level platforms at all important main line stations, low-level platforms at less important main line stations, and rail-level platforms at unimportant wayside stations.

The height of rail level platforms coincides with the rail level, low-level platforms lie at a height of455 mm (1 '-6"), and high-level platforms lie at a height of 760 mm to 840 mm (2'-6" to 2'-9") in the case of BG lines and 305 mm to 405 mm (1 -0" to 1 '-4") in the case of MG lines. Other details of these platforms are given in Table 26.1.
