What is the standard height for a high-level platform on a Broad Gauge (BG) line?

Between 760 mm and 840 mm above the rail level (Clause 4.1.1, Table 1).

What is the minimum horizontal distance from the center of a straight track to the platform edge?

1670 mm for Broad Gauge (BG) lines (Clause 4.3).

What is the recommended slope for a platform surface for drainage?

A cross-slope of 1 in 40 to 1 in 60, sloping away from the track side (Clause 9.1).

What concrete grade is recommended for platform coping?

A minimum of M20 grade concrete is recommended for precast or cast-in-situ coping (Clause 5.1.1).

This code provides guidelines for the design and construction of railway platforms in India. It covers essential parameters like platform dimensions (height, width, clearances), materials for construction, surfacing, drainage, and other associated facilities to ensure passenger safety and operational requirements of the railways.

Lays down guidelines for the design, construction, and dimensions of railway platforms.

Practical Notes

This IS code should always be read in conjunction with the latest 'Indian Railways Schedule of Dimensions' (SOD) and the 'Indian Railways Permanent Way Manual' (IRPWM), which are often the superseding documents for specific projects.

Platform coping dimensions and alignment are critical for passenger safety to prevent undue gaps with trains. Strict quality control during construction is essential.

Platform heights are specified relative to the rail level and vary based on the track gauge (Broad Gauge, Metre Gauge, Narrow Gauge).
