I thought this time we would venture back to a general tribology question.
When turning a curve we know that on modern drive axles the differentials allow the outer wheel to turn faster than the inner wheel in order to avoid dragging/scuffing/slipping that outer wheel.
Train cars have solid axle sets which means the wheels rotate at constant velocity.
Question: How do train wheels avoid this problem?
