Having decided to relay a section of track, part of which includes my program track.
I do not use a separate program track, prefer not to handle my locos on & off.
One end is open, the other enters a point, then onto the main line.
Exit & Entry to the program track is protected with insulated joiners at the frog & outer rail.
The Live Point is a new Peco. The attached frog wire is soldered to a Gaugemaster DCC80 frog switcher.
It shorts even without this.
But, every time a Loco enters or leaves the program track it shorts.
Out of ideas Guys, any thoughts. Regards.
