Two months ago I decided to go DCC on my layout. BAD IDEA !!!! I spent a bunch of money on the Digitrax 602D system and have yet to run a locomotive ! And against the advice I got on this forum, I got rid of all my block switches & rewired the layout without them ! Stupid Me !!!! I've watched a few videos on programing locos & put decoders in two of them. From what I've read, I should get a reading of about 14 volts from the combined voltage of each rail to ground. I only get 4.9 on one and 2.5 on the other !!! Even at the terminals of the DCS 210+. What I need is a Digitrax for Dummies book cause this 76 year guy just don't get it even after reading the instructions & watching videos ! All I know for sure is it's going to take a lot of work to switch back to DC !!!!!
