“I am still working on my 19×13” HO layout and after wiring the whole thing with a 14 gauge bus line and 18 gauge track feeds every 3-5 feet, everything was running smoothly on the entire layout with my MRC DCC 3000. Until one day last week when my most expensive engine stopped moving and another started sputtering with connectivity, yet a third train kept on running. I took off the MRC and put on one of those cheesy transformers and the engines worked a little. So now I’m guessing it’s time to update my transformer. Any thoughts? The part that convinced me was that it’s all been working nicely since upgrading the bus line and feeders.”
