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.

Hello there,
Thank you for your question. I can provide you with an explanation for how a train is able to travel through a curve.
First, let's understand the concept of rotation. When the train is moving, the wheels on both sides are rotating at the same speed. This is because they are connected by an axle and are moving together as one unit.
Now, when the train approaches a curve, the inner rail has a smaller curvature compared to the outer rail. This means that the inner rail has a smaller radius of curvature, which results in a shorter distance for the inner wheel to travel compared to the outer wheel.
So, how does the train maintain its speed while traveling through the curve? This is where the concept of banking comes into play. The outer rail is slightly raised or banked, allowing the train to tilt towards the curve. This tilt helps to distribute the train's weight evenly, creating a centripetal force that keeps the train on the track and maintains its speed.
In summary, the combination of the train's rotation and the banking of the track allows it to travel through a curve while maintaining its speed. I hope this helps to answer your question. Let me know if you have any further inquiries.
Best,
