Dave,?
The isolation track is to protect the main track from being powered by the program track, IF the loco being programmed wanders toward the main and shorts across the track boundary insulators. Some locos move substantially when programmed.?

Hi Bill. But I thought that was the purpose of the auto switch. It senses that you are programming so it de-energizes the main and only programs the program track. If I had 3 locos on the main it shouldn't matter since the autoswitch de-energized the main. Right? ()
Btw, if anyone is wondering where the one line diagram is that I am referring to, it is in part 2 of Track Wiring on Alan's web page ( ).?The one lines are at the very, very end. I am looking at schematic ncedcc4.?
Thank you.?
