As the signal process moves towards completion, I continue to squeeze in other projects as time allows. One of the most recent was adding sound to another locomotive, which always adds a lot to the feel of the operating sessions.
Here's a video for your enjoyment, as I have just upgraded a second SD60I to have sound, bringing my total up to 8 units. More will follow. Both of the units featured here have SoundTraxx GN-1000 sound boards, with EMD 710 sounds. This pair of units comes upgrade through CP-277, past some rudimentary scenery foundation. They really sound excellent - make sure your speakers are turned up!
