Study Notes

Level Crossings and Gatemanship

Level crossings should not be provided on new lines, but if necessary, manned interlocked level crossings may be considered with Railway Board approval.

Safety Measures

Stops should be provided to prevent level crossing gates from swinging towards the track and causing infringement.
Catches should be provided to secure gates when in the open position to avoid obstruction to road traffic.
Two long spare chains with loops at both ends and two red discs with the word "stop" should be kept as reserve equipment.

Skew Level Crossings

Roads should preferably cross the railway line at right angles, but in special cases, the angle of crossing should not be less than 45°.

Classification of Level Crossings

Level crossings are classified based on the volume of rail and road traffic into Special, A, B, and C classes.
The classification criteria include TVUs (Train Vehicle Units) and road vehicle traffic.

Categories of Roads

Roads are categorized into Class I, II, and III based on their importance and traffic volume.

Standards for Different Classes of Level Crossings

Standards for different classes of level crossings are prescribed in Annexure - 9/1, covering parameters such as gates, locking arrangements, and approach roads.

Gates and Locking Arrangements

Gates should be in the form of lifting barriers or swing gates of approved design.
Lifting barriers should be coupled to operate simultaneously, and chains or swing gates should be replaced by lifting barriers on a programmed basis.

Provision of Speed Breakers

Speed breakers should be provided on approach roads to level crossings as a temporary safety measure until rumble strips are provided by road authorities.
Standard warning signs for speed breakers should be provided at a prescribed distance.

Elimination of Level Crossings

A detailed review/survey of existing level crossings should be carried out with a view to eliminate them by constructing subways, grade separators, or road over/under bridges.

Criteria for Replacement of Existing Level Crossings

Minimum Train Vehicle Units (TVU) on a Level Crossing should be 1 lakh per day to become eligible for replacement with Road Over/Under Bridges on a cost-sharing basis.
