DIVERSIFIED METAL FABRICATORS, INC. RW-1630

1.1 GENERAL DESCRIPTION

DMF’s RW-1630 Railgear is our original and very successful Railgear for large trucks. The front

guide wheel assembly attaches to the frame and front axle and lifts the front truck tires 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 damps out the effects of track

irregularities. The rear assembly attaches directly to the truck frame behind the rear

axle/tandem spring hangers. It deploys with an articulating 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 RW-1630 Railgear is designed for vehicles with GVWR’s 33,000 lbs and above. For greater

capacity you can upgrade to our RW-1650 rear gear. It can boost your Railgear weight capacity

by supplying a larger axle, bigger bearings, and special hardened rail wheels. The front

Railgear and all other components remain the same as standard RW-1630. In addition to the

high-capacity axle upgrade available with our RW-1650 Railgear, we also offer additional

options for extreme conditions or tight curvature situations. See Sections 1.2 and 1.3 for

specific configuration information.

For purposes of this manual, we will refer to RW-1630 when discussing either RW-1630 or

RW1630/50, and we will explicitly call out any differences when appropriate.

Materials:

All structural members and brackets are constructed of carbon steel. The 16” guide wheels for

DMF RW-1630 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-1630 Railgear mounts below the

top of frame and directly behind the rear axle spring hangers.

Brakes: NOTE:

The rail wheel brake system is intended to assist the existing vehicle brakes when in the rail

mode. As the vehicle rear tires are in contact with the railhead, the primary braking effort is

derived from the rubber tires. Rail wheel brakes alone are insufficient to stop the vehicle in a

reasonable distance.

The optional RW-1630 rail brakes are of the air actuated external Cobra shoe type. The rail

brakes use a truck style air chamber to supply the clamping force. Supply pressure comes from

the vehicle’s air system. A pressure protection valve separates the Railgear and the truck’s air

systems, preventing a failure in the rail brake system from adversely affecting truck braking.

The rail brakes are applied simultaneously with the truck brakes when the operator presses the

brake pedal. There is also a dashboard-mounted switch that permits the operator to enable or

disable the rail braking system.

Options:

There are several options available for RW-1630 Railgear. The most commonly ordered options

include rail wheel brakes for improved stopping on rail, insulated wheels to prevent crossing

signal actuation, rail sweeps to clear the rail of potentially damaging materials, and remote pin-

offs for ease of operation. Other less common options are non-standard track gauges, slotted

links for improved hi-rail performance at crossings, and two-piece wheels for extreme

conditions.

1.2 FRONT RAILGEAR

DMF’s Heavy Duty Front Railgear is available in 3 different variations. The standard front

Railgear uses a 1630 axle (see section 1.2.1), the Behind Cab variation uses an extra heavy

duty 1650 axle and wheels (see section 1.2.2), and the Under Cab variation uses the 1630 axle

(see section 1.2.3).

1.2.1 Standard Front Railgear Components

Figure 1.2.1 shows the individual parts of the installed front Railgear. These item descriptions

will be used throughout this installation manual. DMF Railgear assemblies are also referred to

as guide wheels, Rail wheels, or hi-rail gear.

1.3 REAR RAILGEAR

1.3.1 Rear Railgear Components (Including RW-1630 and RW-1650)

DMF offers two different variations of Rear Railgear, RW-1630 and RW-1650. The components

are the same, other than the axles and wheels, which have different weight capacities.

RW-1630

GVWR Range: 33,000 lbs. and above

Approx. Installed Weight (Rear): 1185 lbs.

Capacity: 40,000 pounds per Railgear axle @ 20 MPH

RW-1650
