A paint wagon (10) has a base (22) having a plurality of wheels (28, 30) mounted in supporting relation thereto. A drop pin (32) is slidably mounted to the base. The drop pin (32) selectively engages with a conveyor (12) for translating the paint wagon (10) along a path. A plurality of slidably mounted mounting fixtures (26) are movable between a contracted position and an expanded position. An actuating assembly (24) slidably mounts the mounting fixtures to the base. The actuating assembly (24) has a longitudinal support (38) and a plurality of cars (52, 54, 56) in sliding engagement with the longitudinal support. The mounting fixtures (26) extend from the plurality of cars. A rotatably mounted pinion (70) drivingly engages a rack (84, 86) which is slidably mounted with the longitudinal support. The rack (84, 86) is connected to an outer car (56). The rack has a plurality of tabs (90, 92) extending therefrom positioned to selectively engage inner cars (52, 54) to move the inner cars and automatically space the cars. An actuating mechanism (20) is mounted on the path. The actuating assembly (24) selectively engages the actuating mechanism (20) as the paint wagon (10) travels along the path to effect rotation of the pinion (70) and responsively effect the movement of the mounting fixtures (26) between the contracted and expanded positions.

A tamping machine for tamping ties of a track, comprising: a machine frame extending in a longitudinal direction and supported for mobility on the track by two undercarriages; a subframe arranged between the undercarriages and supported for mobility on the track by a further undercarriage; a frame support connecting the subframe to the machine frame to allow displacement of the subframe in the longitudinal direction, said frame support being mounted on the machine frame for displacement perpendicularly to the longitudinal direction; a transverse drive connected to the frame support and linked to the machine frame; and a vertically adjustable tamping unit and a track lifting unit arranged on the subframe between the further undercarriage and the frame support. 2. The machine of claim 1, wherein the frame support has two slide mounts disposed in spaced-apart relationship transversely to the longitudinal direction and connected to the machine frame, and further comprising two frame beams extending in the longitudinal direction and connected to the subframe, and a transverse yoke slidably mounted to the slide mounts for transverse displacement and including two glide bearings in spaced-apart relationship transversely to the longitudinal direction to support the frame beams for displacement in longitudinal direction. 3. The machine of claim 1, and further comprising a measuring device, connected to the transverse drive and to a control device, for detecting a transverse displacement path. 4. The machine of claim 3, wherein the measuring device is designed for detecting a displacement, transversely to the longitudinal direction, of the frame support relative to the track lifting unit. 5. The machine of claim 2, wherein the two frame beams are spaced from one another transversely to the longitudinal direction, said subframe including a transverse beam which connects the two frame beams, and further comprising a push rod connected to the track lifting unit and articulatedly linked to the transverse beam by means of a universally acting joint. 6. The machine of claim 5, wherein the glide bearings are arranged between the transverse beam and the track lifting unit, with regard to the longitudinal direction.
