Thank you so much for making this video Keith. Good stuff!

NOTE: When the update was made to allow for constant voltage, the internal switch mechanism was also updated to the post war type.

Very nice. I have eight post-war O72's. Is there a way to 'modify' the O72 switches, so they don't catch the sliding shoes? Maybe make some kind of insert, that won't interfere with the switch operation, to keep them from catching? I have some K-Line switches that will operate the electromagnetic couplers as the sliding shoe traverses them. I will be replacing them, probably with Ross. Hopefully, they don't have the same problem. An excellent tutorial on the 711 switches.

Nice neat job making non derail switch. But these switches though nice are not in my budget $$. Rather costly per switch. Quality of pre/post war just not available new today.😊😊😊
