While train wheels may look simple, their conical design actually conceals some of the smartest engineering solutions in transport. Far from just trundling along steel rails, it's the shape of the ...

High-speed train wheel dynamics and wear analysis is an essential field focused on understanding the mechanisms that lead to irregular wear patterns, particularly polygonal wear, on train wheels. This ...

BART officials announced Wednesday that a new train wheel design they hope will cut noise by half has passed a battery of performance tests at its Hayward test track and will be introduced into ...
