Do trains have wheels, and what are train wheels called in French?

Expert Answer

Yes. Trains run on steel wheels that roll on steel rails, and the wheelset is usually fixed to an axle so both wheels turn together. In French, the wheels are called roues de train, or more technically roues ferroviaires when speaking about railway components.

What makes train wheels different is their profile: they are not flat. The tread is slightly conical, which helps the train stay centered on the rails and follow curves smoothly. The outer wheel in a turn travels a slightly longer path, and the conical shape helps that difference happen naturally without a steering wheel.

If you were asking because you saw a train up close, the visible parts are the wheel, the axle, and often the bogie or truck that carries the wheelsets. In railway terminology, a single pair of wheels on one axle is a wheelset. For rail systems and heavy-duty running gear, wheel profile and alignment matter a lot because they affect stability, wear, and noise.
