The near corner of the roof being out of focus is the biggest giveaway for me, but it took me a minute. What makes models look small is the narrow depth of field available at close range with most cameras. This is just barely visible here, though, fantastic camera work and details on the models, it really does look real at first.
Lovely layout. The video is great. I like the fact that there were a few moments where all you could hear was the train coming but couldn't see it. Very well done.
