A track guided vehicle is provided which includes laterally projecting transverse guide rollers mounted on support arms extending in a direction parallel to a direction of travel of the vehicle. The guide rollers are adapted to be retractable and extendable to an operating position through a guide arrangement which is directed diagonally upwardly and inwardly with a bilaterally effective operating element being disposed concentrically within the guide arrangement. The transverse guide rollers are elastically flexible in a transverse direction and are adapted to utilize an on board compressed air system to displace the transverse guide rollers and fluidic operating or working element which is constructed for pneumatic pressure application. In order to be able to apply a sufficiently high transverse retaining force with a limited air pressure available from the on board compressed air system of the vehicle, thereby providing the largest possible effective piston area for the guide arrangement, an inner surface of the hollow guide column forms a cylinder of the operating or working element, with the cylinder being adapted to move relative to a fixed piston of the operating or working element.
