can someone explain cant deficiency in railways the explanation of super elevation is hard to imagine from the explanation on the web
In: Engineering
Superelevation is when railway tracks on a curve are tilted ( canted) so the centrifugal forces on a train trying to make it fly off the tracks are balanced by shifting the centre of gravity inwards. It is analogous to a cyclist leaning into a corner.
The higher the planned speed, the higher the superelevation.
But there is a limit to how high superelevation can safely be, if a train goes round a bend slowly, or stops the superelevation must never be so high that the centre of gravity tips the train inwards.
Cant deficiency is when the tilting doesn’t balance the outward forces of the speed of the train.
