Train wheels aren't flat like a soup can—they're subtly cone-shaped, and that small detail is one of the key reasons massive locomotives stay locked onto narrow steel rails. This episode breaks down the clever engineering behind train wheels, rails, and track switches in language designed for curious kids. Along the way, listeners learn why trains don't need a steering wheel and how simple geometry keeps thousands of tons of metal safely on course.
