The axle can be driven together with the wheel by means of a drive motor. The trolley provides a reliable transmission of drive forces between the wheels and the rail with the drivable first wheel connected to at least one of the other wheels in a driving manner via a flexible drive such that the axle is arranged between the drive motor and the flexible drive and thus the flexible drive is connected downstream of the axle in a driving manner so that the flexible drive can be driven by the axle.
