Hello, Please help me to find out the answer for the following question...!!! When a train is running, wheels at both sides are rotating with a same speed . So when it runs through a curve, the inner rail is having a small curvature than the outer rail. So Outer wheel has to travel a long distance than the inner wheel . So if both side's wheels are running with same speed, how it happens ? What is the magic here. Is it realted with Banking of curvature concepts. Please, anybody can provide some expert opinions for the above question..? Thanks in advance..!!!
