I am fairly new to the hobby, just upgraded my track from Lionel to Garagraves and switches from Lionel to Ross. Ran 16 gauge bus wiring with track connections about every 8'. Running TMCC and having difficulty trying to figure out the wiring for the Ross 175, the engines run fine when they run straight through the switch, but lose power briefly at the diamond when I use the crossover. My transformer is a ZW with 2 135's. Do not plan to wire the z1000's until the 175 works properly. Any suggestions would be deeply appreciated.
