I love my RailPro system. I run it alongside my DCC equipment. The one thing that I was not going to do was replace the DCC decoders that are already installed only because of the cost. I have almost 100 engines, most running DCC. Well, that idea went down the tubes. I have converted 3 of my engines to RailPro, throwing the DCC decoders in an old box. And I just ordered more LM-3s to convert more engines.
I'm hooked!
