DCC installs in brass steam?

brian1961go <brian1961go@...>
 

I have learned that is fairly difficult and/or expensive to install
decoders into brass due to isolating the frame. Does anyone have any
suggestions?

My one thought is to have stock car with several different sound
decoders based on engine type and always have it hooked to the tender
but how do I wire it with just one speaker?

TIA, Brian
