REGULATION FOR ELECTRICAL CROSSING OF RAILWAY TRACKS
9.0 Provision of the regulation for power line crossing of Railway Track, 1987 are
given below.
9.0.1 Power line crossing up to and including 11kv require to be cabled and crossed underground
9.0.2 Power Line Crossings up to and including 33kv is recommended to be croosed
through underground cables.
9.0.3 For overhead crossing of power lines, the minimum height above rail level to the
lowest conductor including the guard wire shall be as given below.
Voltage(kv) Minimum height
above Rail level(m)
above 11 to 66 14.10
above 66 to 132 14.60
above 132 to 220 15.40
above 220 to 400 17.90
above 400 to 500 19.30
above 500 to 800 23.40
9.0.4 The angle of overhead crossing shall be perpendicular to the track. In exceptional cases
it may be permitted with a skew, the angle of deviation not exceeding 30 degree. In case it is
likely to be more than this value the case should be referred to the Electrical Inspector to the
government (Chief Electrical Engineer of the open Line Railway).
9.0.5 In view of high cost of modifications to Power Line Crossing and also difficulty in getting
shut down of important transmission line crossings of tracks contemplated to be electrified
Electrical inspectors to Government may approve crossings with lower heights provided the
clearance between lowest conductor of the power line to the highest traction conductor under
most adverse ambient temperature condition is as indicated below.
Voltage(kv) Minimum clearance(m)
0 to 66 4.44
above 66 to 110 4.75
above 110 to 132 5.05
220 6.58
400 9.71
500 11.45
800 16.67
If power line crossing has guard wire minimum clearance from the guard wire to the highest
traction conductonr should be 2 m
