Correct Answer - Option 4 : C = GV
2/127R
Explanation:
Equilibrium superelevation/cant:
It is the difference between the height of the outer rail and the inner rail on a curve.
Inner rail is taken as the reference rail and with respect to inner rail, outer rail is raised.
The objective of providing a superelevation: The objective of providing a superelevation to neutralize the effect of centrifugal force, achieve equal distribution of wheel loads, improve the comfort level of passengers, etc.
Superelevation or cant C = GV2/127R
Where
R = radius of rail in meter
V = Speed of train in km/hr
G = gauge of track
The maximum permissible limit for actual Cant or superelevation
