This installation is the subject of my January 2013 column in Model Railroad Hobbyist magazine. CLICK HERE to view that column.

A video of this installation is available from Model Railroad Hobbyist magazine: CLICK HERE. In addition to the specifics of this installation, this video provides a comprehensive look at basic methodologies for DCC conversion of many different types of locomotives.

Machining the frame is pretty straight forward. Remove enough from the top to clear the decoder and enough from the fuel tank to clear the speaker. Then machine four slots on each side to bring the wires up.

As you can see in the photo above, the rear light is wired to the front of the decoder and vice-versa. The deocder MUST be installed backwards (front end facing the rear). Below the rear of the decoder are two large electrolytic capacitorrs. They would interfere with the motor if the decoder were installed in the normal direction. I chose to cross wire the lights, wiring them to the intended terminals, not the closest ones. This avoids having to reprogram the function outputs.

Here is the locomotive ready to move the shell down onto the frame. It shows the wiring to the trucks and the speaker (which is mounted in the fuel tank).

The DecoderPro (.XML) file I used as a starting point for programming this loco is available. CONTACT BRUCE for a copy.
