How train is travelling through a curve?

[aneeshk]

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..!

No banking is necessary. The inner wheels slip on the rail.
