Abstract: The rail vehicle, especially for a streetcar or metropolitan transit car for local traffic, includes a car body (1) and an undercarriage (2) nonrotatably connected with each other by respective guide rods (3) each extending in a longitudinal direction. The connector members (3a) of these guide rods (3) facing the car body (1) and the corresponding receptacles (4) for them attached to the car body are arranged together in the central plane (M) of the undercarriage, which extends perpendicularly to the vehicle longitudinal axis (L). The connector members (3a) and the corresponding receptacles (4) are arranged together in the central plane (M) in a symmetrical arrangement so that a rapid reversal of the running direction of the undercarriage may be performed by only releasing the guide rods from their receptacles, rotating the undercarriage by about 180° and reconnecting the guide rods to the receptacles without moving the undercarriage from the first head end to the second head end of the car body (1).
