摘要 The invention relates to a retractable step arrangement for a rail vehicle with a first housing that can be mounted on a body of the rail vehicle and features a first housing opening, with a step that is movably supported in the first housing in an initial position and can be displaced between the initial position and a final position, in which the step at least sectionally protrudes from the first housing, through the first housing opening, and with a drive unit for the step that features a motor and at least one movable connecting means that transmits a motion generated by the motor to the step. The retractable step arrangement provides a separate second housing, in which the drive unit is arranged, wherein the interior of the first housing is spatially separated from the interior of the second housing.
