After doing a bunch of experimenting with DCC sound over several years I had decided that instead of installing sound decoders in my N scale locomotives I would use just a few as stationary sound decoders in choice locations addressed to the locomotive working in that area.
To start with, I wanted to have the sound for the yard switcher in Carlin yard. One of the small speakers was placed inside of one of the buildings across the street from the yard about in the middle. It was glued down to the base as shown here.
The building that will go here is a Design Preservation Models Hayes Hardware kit shown here half finished. It will be a hotel when it's finished. Look for a future post on that project.
Because I sometimes change locomotives assigned to the Carlin yard, I would need to be able to program the sound decoder to an address matching the address of the locomotive. I installed this control panel on the fascia which allows for this. Thinking ahead, I also included control for the road switcher assigned to the Carlin yard as that will be a future step. A cable for the programming output was run around the layout from the command station to this panel.
The Digitrax SFX0416 decoder is quite small and was placed within the bench work behind the control panel. It is pointed out with a red arrow in the photo below.
