I think I might convert my layout to DCC. The motivation is running consists of locomotives. Over the past few months I have four Atlas GP38-2's. Unfortunately they all run at slightly different speeds, and only two of the four are close enough in speed that I feel comfortable running them as a pair without worrying about stressing the motors. If I go to DCC I want to redo the track to remove all the insulating rail joiners that I used for DC blocks. I also might need to redo the bus wiring. I had 16 gauge speaker wire as the bus before, I don't know if that will hold up for DCC. I have seen 14 gauge in a lot of places but I have a small layout (only door sized). I think that is a wait and see how the load if I get the DCC system. How easy is speed matching in DCC?
