Santa Fe’s Raton Pass: Model Railroad: Sound Decoder Test Run

Scroll down to content

As we complete the painting of locomotives in the Dean Collection, DCC Sound decoders are installed. Engine 3526 shown below in its unpainted just-out-of-the-box condition was gone over mechanically and checked for smooth running. A few things had to be corrected, the original Pittman motor was replaced with a can motor. Then, the locomotive was sent to the workbench to test the running characteristics. After some minor adjustments the locomotive was found to be a smooth runner.


The engine was then taken apart and sent through the painting process.  This locomotive is modeled after a Santa Fe Railway, 4-6-2 3500 Class. We look up the locomotives in our archives and check for the proper paint scheme and decals to be sure it will have a prototypical appearance when completed.

This model already had the floor bored for the speaker. The only drilling we had to do was for the headlight.

After the locomotive has been painted and allowed to cure, the DCC Sound decoder installation process can begin.

The video below shows unit 3526 being tested after installation of the decoder and speaker inside the tender.  Once everything works well, we install the front and rear trucks, hook up the headlight and put the boiler/cab assembly onto the drive assembly to complete the project.
