Abstract
A shift control arrangement is provided for rail vehicles to bring about the simultaneous shifting of all directional guide wheels on the vehicle at the same time, including those in both the front and rear undercarriages of the vehicle. This is achieved by interconnecting the shift linkages of each undercarriage and, preferably, by placing the connection in the longitudinal axis of the vehicle.
