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.
Superelevation is where one rail is higher than the other rail during a curve. Similar to the bank you would see on a NASCAR racetrack during turns in the track. Superelevation helps the train turn while minimizing strain on the outside rail and the train wheels. If the track is not superelevated enough, or the train is going too fast for the amount of superelevation, then there is too much strain on the outside rail and the outside wheels of the train and you would call the condition “cant deficient” because there is not enough of a “cant” in the track to balance the forces.
This title is extremely poorly written. If you want an answer I’d try rephrasing this so it makes sense.
