What is the scope of this part of the code?

Part 4 specifically covers the requirements for physical gates and barriers used at railway level crossings.

Does this code specify the colour of the barriers?

Yes, it typically specifies alternating red and white or yellow and black bands for high visibility, as is common practice.

Is this code still the primary reference for level crossing gates?

While technically active, the Indian Railways' own internal manuals and standards are the primary and more current reference for all railway infrastructure projects, including level crossings.

This standard provides a code of practice for the design, construction, and installation of gates and barriers at railway level crossings. It covers various types of gates, including lifting barriers and swing gates, detailing their operational, dimensional, and safety requirements to protect road and rail traffic.

Specifies requirements for the design, construction, and operation of gates and barriers at level crossings.

Quick Reference Values

Minimum height of gate/barrier above road surface1.2 m

Minimum clearance between bottom of boom and road surface0.9 m

Typical operating time for lifting barriers10 to 15 seconds

Visibility of gate/barrier from roadSufficient distance for a driver to stop safely

Width of gate leaf for single lane road (approx.)3.0 m to 3.5 m

Practical Notes

This is an older standard. Its provisions should be cross-verified with the latest Indian Railways Manuals (e.g., Permanent Way Manual, Signal Engineering Manual) and circulars, which are updated more frequently and contain the current mandatory requirements.

The choice between lifting barriers and swing gates depends on the class of level crossing, traffic volume, and operational constraints specified by the zonal railway.
