Typical Chassis

DMF RW-1015 railgear is designed for pickup and SUV chassis from 8,000 to 12,000  lbs. GVWR, such as:

  • GM 2500HD Pickup & Cab Chassis
  • GM 2500 Pickup
  • Ford F250 Pickup
  • Ford F350 SRW Pickup & Cab Chassis
  • Ford Ranger (2012+)

Please contact DMF for details on ordering chassis. We can provide advice on what options are most suitable for hi-rail application. Some wheel options, fuel tanks arrangements, and other non-standard items such as auxiliary AC units can prevent or complicate installation.


Standard Features

  • Velcro™ Steering Wheel Lock
  • Emergency Hand Pump
  • Rubber or Steel Guide Wheels
  • Push-Button Bumper-Mounted Controls
  • Hydraulic Locking Valves
  • In-Cab Control


DMF RW-1015 railgear is designed for application to pickup and SUV chassis from 8,000 to 12,000 lbs. GVWR. It is only applicable to vehicles with single rear wheels. RW-1015’s adjustable suspension, easy operation, and numerous safety and convenience features provide a smooth and sure ride.

The RW-1015 railgear typically stows within the length of the vehicle, eliminating the maneuvering and parking problems long associated with hi-rail vehicles. Without railgear protruding in front and behind, working around the vehicle is easier than ever. Access to the truck bed or rear hatch is not affected.

RW-1015 is hydraulically operated from a control panel in the cab or by switches at the front and rear of the vehicle. A hydraulic cylinder moves the railgear from the nearly hidden stowed position to the rail position in seconds.

RW-1015 uses a rubber compression suspension at each guide wheel to improve on-rail ride and negotiate track features such as guarded frogs. Both rubber and steel tread guide wheels are available.

On RW-1015 equipped vehicles, all vehicle tires ride on the rail allowing the railgear to be lighter, minimizing the impact on payload. This requires aftermarket wheel kits on full-sized pickup and cab chassis.

Additional Details

Safety Features: The railgear incorporates safety features to address the possibility of hydraulic failures. The railgear is “over-center” in the rail position preventing a leak from allowing the railgear to move from the rail position. In the event of complete hydraulic failure, the system is equipped with an emergency hand pump to allow the vehicle to be removed from the rail. In the stowed position, the railgear is retained by hydraulic locking valves.
Materials: All structural members and brackets are constructed of carbon steel. The guidewheels are made from steel castings. Spindles are made from high strength alloys and use heavy duty tapered roller bearings.
Installation: DMF RW-1015 railgear is mounted to the front and rear frame using tools common to any service shop or up-fitter. The front bumper is trimmed at the corners to allow for the front railgear in the stowed position. In some applications, service bodies require modification to accommodate railgear. The installation kits come with a partially pre-assembled wiring harness that accommodates all chassis and simplifies installation.
Operation: The vehicle is pulled onto a crossing and aligned with the track. The rear is closely aligned and deployed. The front is steered into alignment with the rail and deployed. Once the position of the railgear is verified, the operator returns to the cab, straightens the steering wheel and installs the steering wheel lock. The vehicle is ready to proceed. Getting off the rail can quickly be done from the cab.
NOTE: This is an abbreviated procedure, please consult the manual for complete step-by-step instructions and cautionary information regarding the operation of your hi-rail gear.
