I run MTH trains on two separate tracks. TIU Fixed 1 is connected to outside track. Fixed 2 connected to inside track. DCS works fine on Fixed 1(Engines (Proto 3) Run). However, Fixed 2 on inside track, engines do not run (DCS controller says "Out of Range"). Tested current on inside track and there is 19.4 volts. Conventional engine runs on it. Placed Fixed 2 on outside track (to see if it works) and MTH engines (Proto 3) run. I am puzzled, what could be the problem? Daviddp
