Abstract
A track maintenance wagon (1) for picking up and/or laying a track panel (10), comprising a wagon frame (2) supported on on-track undercarriages (4), wherein two longitudinal beams (7) of the wagon frame (2) delimit a free opening and are transversely displaceable relative to one another, so that the free opening is changeable as to its width and, in a working position, has greater opening dimensions as a horizontal projection of the track panel (19), and wherein crane rails (8) are arranged on the longitudinal beams (7) for a gantry crane (11) mobile in the longitudinal direction (3) of the wagon. In this, buffers (13) are arranged at two free ends (12) of the longitudinal beams (7).
