SUMMARY

When a train navigates a curve, the wheels on both sides rotate at the same speed despite the differing distances traveled by the inner and outer wheels. The inner rail has a smaller curvature than the outer rail, necessitating that the outer wheel covers a longer distance. This phenomenon occurs because the inner wheels slip on the rail, allowing the train to maintain a consistent speed without requiring banking of the curvature. Understanding this mechanism is crucial for grasping train dynamics during curved travel.

PREREQUISITES
  • Understanding of train wheel mechanics
  • Knowledge of rail curvature concepts
  • Familiarity with the principles of friction and slipping
  • Basic physics of motion and forces
NEXT STEPS
  • Research the mechanics of train wheel design
  • Study the effects of rail curvature on train dynamics
  • Explore the principles of friction in mechanical systems
  • Learn about the engineering behind banking in railway tracks
USEFUL FOR

Railway engineers, physics students, and anyone interested in the mechanics of train operations and dynamics during curved travel.

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..!:cool:

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