Abstract: A bogie for a self-propelled railway car comprises a brake for at least two wheel sets, the axle of one of which can be driven by an electric motor through a gear train. According to the invention, not only is the support frame mounted upon a pin depending from the vehicle chassis and a secondary spring suspension provided between this frame and the chassis, but the pin also carries at least part of the weight of the motor and drive train and/or the brake system. Both the drive train and the brake system are connected to the driven axle by a universal joint shaft arrangement and a primary suspension is provided between the axles and the frame.
