Abstract: A door drive device for a door of a wagon, including at least one door panel mount displaceable along a first spatial axis substantially vertical to the plane of a door panel mounted on the at least one door panel mount and along a second spatial axis extending substantially horizontal in use and substantially vertical to the first spatial axis, a drive motor and a spindle which may be rotated by means of the drive motor. It is provided, that a displacement of the at least one door panel mount along the first and/or second spatial axis is effected by means of a guide fork being displaceable by an associated spindle nut slidably engaged with the guide fork, wherein the spindle nut is driven by rotation of a spindle and wherein the spindle and the drive motor are fixed with respect to the wagon.
