Can someone tell me how and what items i would need to make this DCC with sound?
BNSF Dash 8
If you can find one with sound, you might be able to swap the shells.
That or get a QSI-revolution type-A (Atlas lightboard-type) with the right sound files and a speaker. If I recall right, atlas silver and gold (with sound/DCC) usually use the same frame, so there might be a space for the speaker.
Edit; here's one with sound for the same price:

Wants: 1. high-quality, sound equipped, SD40-2s, C636s, C30-7s, and F-units in BN. As for ones that don't cost an arm and a leg, that's out of the question....
2. An end to the limited-production and other crap that makes models harder to get and more expensive.
