Somewhere I read an article about using a sound decoder under the layout wired to computer type speakers. This was programmed to run as a consist with what ever Loco you wanted. Of course I forgot where the article was. Can you guys and gals help? Also would like to know which decoder falls into decent but not to expensive.
The basic idea is pretty simple, you have say an EMD sound decoder attached to the DCC power going to the rails, and connect the sound output up to a small stereo system with speakers under the layout, and assign it an ID no. like 100. Everytime you run an EMD engine on the layout, you m.u. “engine” 100 to a consist with the engine you’re running.
I did the under layout sound thing myself but instead of a sound decoder I used the MRC diesel sound box and hooked it up to a 5.1 surround sound speaker system (after disabling the center woofer) and set the speakers out at different locations on the layout.
A few years ago SoundTraxx was working on a system where the sound follows the train around the layout. There have also been many threads about this sort of system.
