As I understand it, you don¡¯t need an isolated program track IF the only Loco on your layout is the one you want to program. ?Without isolation every Loco will be programmed. ?By isolating the program track, the programming signals are sent only to the Loco on the programming track. ?And by by-passing the ¡°programming-out¡± terminals on the auto-switch, you can use the program track to run trains when not in program mode.?

?Hi - On this one-line diagram Jim shows the autoswitch wired to a programming track with an isolation track. I understand that the purpose of the isolation track is to keep you from accidentally driving your loco on to the Layout which would cause issues. Here's my question: isn't the isolation track redundant in this case? The purpose of the auto switch is to detect programming data being sent from the power cab and subsequently killing power to the main. If there is no power to the main then why do you need an isolation track?
Im sure im missing something just like to know what it is.?
Thanks.?
