A bogie is capable of being moved from a rest configuration to an active configuration in which the bogie carries at least one vertical load. The bogie includes a chassis, at least one pair of wheels, and a shaft extending along an axle axis for each pair of wheels. Each wheel has a wheel hub extending along a hub axis and an axle box attached to the chassis and receiving the associated hub. Each hub is rotatable relative to the associated axle box. For each hub, the hub axis forms a non-zero camber angle with the axle axis of the associated shaft when the bogie is in the rest configuration.
