    摘要： A railway car includes prime movers mounted to a car body directly connected to pairs of gear boxes to drive pairs of axles mounted on a pair of trucks, with direct connections between the gear boxes and the connections being such so as to permit independent removal of the trucks from the prime movers and to facilitate the installation of interchangeable variable speed drives.

    摘要： A transmission for the power-train of a rail vehicle, in which the transmission (3) includes an input shaft (4), an intermediate shaft (5) and a drive output shaft (6). The input shaft (4) can be connected so as to be driven by a drive motor (2), and the drive output shaft (6) forms a wheelset shaft of the rail vehicle. The transmission (3) has at least two selectively shiftable transmission stages with different transmission ratios for the same travel direction, and a shifting device (7) for engaging the transmission stages. Furthermore, a power-train for a rail vehicle having a transmission of such type is proposed.
