ABSTRACT:
A rail guide wheel arrangement provides movement of rail wheels between rail and road positions with a compact zone of movement such that no open zone is required in front or behind the apparatus to accommodate such movement. The movement of rail wheels and a wheel support has no component of movement in the rail direction. Side shifting of the guide wheel unit can be controlled by control arrangement using a single joystick to control two actuators. A suspension is provided using two spring cells. An axle may include cavities to receive the spring cells when the apparatus is in its road position. A locking arrangement uses pilot operated check valves and secondary mechanical locks.
