Thank you for the help. I "see" what you're saying although I don't understand electricity, so thanks. If I could ask a couple of random questions-
I have a 3 wire news stand and a 3 wire watch tower, both work fine. They engage with the train crosses isolated track. They run on 14V buuut - not the banjo? Is it actually hooked up different because 2 wires VS 3 wired accessory?
Does it matter which rail you isolate? I mean both are ground so why the outside one. Just to be uniform?
Second throttle is being used- I might just get a small transformer and hook all my banjo/crossing gates to that.......With 2 trains on 2 sepárate track- can I hook up ALL accessories that are on BOTH track to that one transformer? Or a separate power source for each.
Thanks so much! Here's a video for your help!!
