@c.sam posted:Is it possible to covert a 3 rail AC system to DCC with sound? Thinking that as our MTH and Lionel locomotive control systems fail, might it be more economical to go that route and perhaps over 5 to 10 years we will have converted our whole roster one by one 'as needed'?
It's absolutely possible. However, I think there are probably some features that may be more difficult to keep working with DCC. Things like blowdown steam, whistle steam, and other "sound effect activated" features.
If we limit the conversion to direction, speed control, smoke, whistle, bell, engine sounds, electro couplers, and lighting there's no reason it can't be done.
