That's OK Scott, I went through that exercise 4 times prior to shooting that. At least it was still doing it with the camera on. It was nice to be able to time the duration of the event. Previously, I would just flip the switch, hear the trains moving, and quick flip it off. I didn't have trains as well isolated, so I never left them on long enough to really see what happened.
I still haven't figured out where the track power came from, and then 10 seconds later it goes dead, likre it was supposed to.
