Explain the working of differential in a train

Question

Accepted Answer

The differential in a train allows the wheels on the same axle to rotate at different speeds, enabling smooth turns.

The differential is a device that splits torque between the wheels on the same axle.
It consists of a set of gears that allow the wheels to rotate at different speeds while maintaining power distribution.
During straight-line motion, the differential allows both wheels to rotate at the same speed.
When the train turns, the outer wheel covers a longer distance, so the differential allows it to rotate faster than the inner wheel.
This prevents wheel slippage and ensures smooth turning.
The differential also helps in distributing power evenly between the wheels, improving traction and stability.
