Having recently decided to dust off my trains, I went online and noticed "regular" trains (DC) were no longer the only option. Granted, it's been a few years that I've been away from the hobby (like 35+ years away), I was intrigued by DCC. But I didn't want to disregard my DC engines. This controller gave me the best of both worlds ! My brand new Kato P42 with sound decoder ran perfectly, as did my old DC trains from the 1970's ! I can see the attraction of DCC, but I also like going "old skool" with my DC boyz.
