Mobile track vehicle

An improved self-propelled mobile track vehicle (MTV) capable of traveling by road at normal highway speeds and traveling by rail after conversion at a narrow railroad crossing by producing a device for rotating the vehicle 90 degrees. The vehicle is powered by a diesel engine driving through a power shift transmission to the roadway and railway axles. A significant advantage over other types of road / rail vehicles is that 100 percent of the vehicle's weight is carried on the rail wheels, which are powered and braked, thereby allowing higher and safer rail speeds. One way to convert the vehicle from roadway travel to railway travel is to maneuver it into a position parallel to the track at a road crossing. The rail axles are then extended and road axles retracted. In addition, a turntable mounted at the vehicle's center of gravity also allows the vehicle to convert at a narrow road crossing. While at railway / roadway crossing the unit raises and rotates 90 to align with the desired roadway or railway. The vehicle can assist in starting a train by extending the powered road axle so that the inner rubber tires contact the rail and the high traction of rubber on rail assists in increasing starting traction of the vehicle thus allowing the vehicle to assist in starting a train.
