Grade Compensation on Curves of Railway Track

Grade Compensation on Curves of Railway Track

If a sharp horizontal curve is provided on a railway track with a ruling gradient, the tractive resistance will be increased due to this curve. In order to avoid this resistance beyond the allowable limits, the gradients are reduced on curves, this reduction in gradient at the horizontal curve is called grade compensation on curves.

In Indian Railway, the following are the grade compensation have been recommended.

Gauge     Grade compensation 

B.G Track – 0.04%
M.G Track – 0.03%
