Wow, your layout is looking really nice, Alan. I especially like all the texture you have on the road in that last picture.
I've never constructed nor operated a small switching layout like this, but someday I hope to. I daresay, however, that I would find more enjoyment in continuous running. Sometime about setting the train 'free' and not having to look after it for a few moments. I also like to have them running around in loops in the background while I work on projects.
Cheers
