Thanks to both Trainman and Rich. The TCS link is exactly what I have been trying to find. Now I just have to practice microsolding before I make the leap.

Just as a side bar, in addition to my upstate NY village DCC layout, I bought a Bachmann EZ app Bluetooth steam loco set for my 2 yr old grandson. The loco sounds from my iphone were very disappointing so I'm setting up a 1" cube Bluetooth speaker($8) placed in a Bachmann 40' stock car. Saw this setup on a Bachmann video.

All the best,
John

Hi Folks,

What is the easiest method of adding sound to a Spectrum 4-4-0 DCC Modern GN?

Thanks,

John
