I will be making an Express Mail Rail truck for the L&R Railroad. Just what exactly I will be putting into this, and how it will eventually look, will play out as the construction goes forward. Here are the two items that will be used in this Rail truck construction. With Spring now here, and Summer just around the corner, we’ll see how far this gets to completion.

The plastic truck kit used will be a 1/72 scale PST model PARM -2 Field Repair Truck, Kit #72024, and one powered truck from a 1/87 scale Bachmann 44 Tonner for motive power.

Looks like that truck has a lot of potential. This should be interesting to follow.

Before the truck is constructed, I will be re-wiring the Bachmann truck for use with DCC first as shown and described in the pictures below. Then the truck kit can be modified and built around the motor unit to fit. I will be posting pictures of the powered truck when I have completed the re-wiring process.
Frist I have to crack open the Bachmann drive unit and clip the brass connectors from the truck wheels to the motor, to isolate the unit, then solder the orange and gray wires to the motor, and solder the red and black power pick-up wires to the brass wheel pick-ups.

Thanks for the wiring information. I have an extra 44 ton loco I plan to use to power a doodlebug - someday.

Always a pleasure George. These older 44 Tonners come in handy for these types of builds. Infact, the motor for the Bachmann doodlebug is not much different from these little babies.

At this point, if you were using this conversion for any other type model, it is ready for a decoder and run with it. That's all there is to making this thing DCC ready.
To crack open the Bachmann 44 Tonner drive unit, there are four screws on the four corners of the top that have to be removed, once removed the top comes off and the motor can be pulled out of the frame. You can see from picture #4 the two brass connectors that have to be clipped down for the red and black pick-up wires. Looking closely at picture #4 one connector is in about the middle of the truck, and the other connector is just above the truck in the picture. These use to connect to the bottom and top of the motor contacts for power from the trucks that are no longer needed. Also in picture #4, there is a (+) emblem on the motor (hard to see in the front, top right) the lug that you connect the orange wire to, and your gray wire to the other lug. Once the orange and gray wires have been soldered, the motor can be returned to the frame. The last picture shows the wires in place, and twisted on top of the drive unit to enter the Rail truck rear box.
