wheelsets

Axle-mounted wheel pairs

Wheelsets are paired wheels connected by a rigid axle, functioning as a single unit in railway vehicles.

Each wheelset allows a train car to roll along tracks while maintaining proper gauge and alignment.

The term appears primarily in railroad engineering and model train contexts, where wheelsets are fundamental components that bear the vehicle's weight and guide it along the rails.

The locomotive required new wheelsets after years of heavy service.
