I counted 7 or 8 short trains before the camera panned to the right. I have to agree with Frank that for one reason or another all of the trains were returning to the same location or sections of the trains would be left at locations along the way. I do know one thing. It didn’t appear that it was moving very fast and I would HATE to be sitting a a crossing waiting for it to pass. Especially if I needed to get to the bathroom. �� LOL. It was still a pretty cool video though.
