DMF’s RW-1019 railgear is a scaled-down version of our patented and very successful RW-1630 gear for large trucks. The front guide wheel assembly attaches to the frame and front axle and lifts the front wheels off the track, thus, utilizing the vehicle’s front suspension. This design supports the vehicle as it was intended and helps the truck navigate curves smoothly and dampen out the effects of track irregularities. The rear assembly attaches directly to the truck frame behind the rear axle spring hanger. It deploys with an articulated dual-scissor action that allows the rear railgear to be moved both vertically and horizontally. This mechanism provides the “side-shift” action which has made DMF gear so well-known in the industry. It gives operators a greater margin for aligning the vehicle to the track which speeds and simplifies the process of getting the vehicle on rail.


DMF now offers an updated alternative to our popular 1019 railgear. 1019B rear railgear is a compact design which straddles the rear fuel tank and eliminates the need for frame extensions. When deployed, the rear railgear axle is positioned very close to the vehicle’s tires for maximum curvature performance. 1019B front railgear offers improved front ground clearance and requires minimal front bumper extension. These improvements result in a more functional, maneuverable, and aesthetically pleasing completed vehicle. This design was specifically created to accommodate the standard rear-mounted fuel tanks on most chassis. 1019B railgear features a unique swinging deployment path that offers the reassurance of a true over-center design at both the front and rear. Locking safety pin-offs are easily actuated from the bumpers. 1019B railgear installations do not tie into the vehicle suspension, require no welding to the truck frame, and make use of factory frame hole locations where possible.

Additional Details

Materials: All structural members and brackets are constructed of carbon steel. The 10″ guide wheels for DMF RW-1019 railgear are machined from hardened steel castings and are fitted to high strength alloy steel axles with heavy-duty tapered roller bearings.
Installation: Both DMF front and rear guide wheel units bolt to the truck frame using only hand tools found in any shop. They are designed to minimize the amount of space required and in many cases fit within the existing boundaries of the vehicle. The front units, however, sometimes require a bolt-on frame extension to complete the installation. Rear RW-1019 railgear mounts below the top of frame and directly behind the chassis spring hangers. This minimizes intrusion into truck body installations. Please note that center-mounted fuel tanks behind the rear truck axle are not desirable. If possible, opt for the mid-mounted tanks.  Rear-mounted tanks can be accommodated by using RW-1019B railgear.
Brakes: RW-1019 rail brakes are hydraulically actuated external shoes. The hydraulic power unit that raises and lowers the railgear also operates the brakes. When the dashboard mounted enable switch is turned on, the brake lamp signal is used as a trigger to run the pump and divert hydraulic pressure to the brakes assisting the existing vehicle brakes when in rail mode. A built in safety circuit protects the truck’s brake lamp system as well as the hydraulic power unit from excessive run times.
Operation: The truck is pulled onto a crossing and the wheels aligned to the tracks with attention being paid to the front. The operator then activates the hydraulic power unit by pressing the button on the front bumper and pulling the lever of the hydraulic valve to raise the railgear off of the pin-off device. The safety pins are removed and the lever pushed forward lowering the rail wheels to the track. The front gear will lift the front of the truck and go over center. The rear is operated similarly. The gear is raised to lift the weight from the pin-offs, and the pins are removed. The gear is then lowered via the two handled valve at the rear of the truck. Each spool may be operated independently to articulate the rear gear and engage the rail even if the rear wheels are not perfectly aligned. Once the rear gear is fully deployed, the pin-offs are re-inserted to lock the gear in place.
Steering Wheel Lock: A steering wheel lock is provided, requiring no modifications to the column.
