Dave, I like that 'double reverse with a twist' you have created there. That's a pretty neat idea for reversing both ways and not using a ton of space. Probably more space than it appears I guess, but I still think it's a good idea.
I'm just thinking here, but it would be neat of that could be tucked below somehow where the train goes down and reverses and comes back. Maybe something I could incorporate here as well? Ok, now I'm going back to my observation post in the back...to continue watching and stop commenting.
