Mr. No, I would love to have you come and do that if you are ever in our area!
I've zoomed in on it, and yes. It is TrackMaster 1 track, though he doesn't seem to have shown the rest of it yet.
The western buildings are from Ertyl playsets. They fit in pretty well with o scale trains. Most of the city buildings are card stock. I bought the designs from Fat Dragon Games. I have access to a color printer so its an inexpensive way to create a big city. I have ground tiles to go with them but didn't take time to put them out this year. The train display is a bit of a mashup of items this year but the overall affect isn't too bad. The two alien looking figures are actually school girls jumping rope. Ill get a closer picture later. Its part of all the winter village items my mother gave to me years ago. And lastly, yes you have sharp eyes, there is a Trackmaster I layout next to the western town. A new guy helped with setup this year and brought his young son along. I let them set those trains up. Honestly, it also kept small hands off the big expensive trains while we were working. Ill get a picture if it for you.
The Lionel Train Layout is yours too Bob?
