All the major trackwork for the layout is in place! Finally pinned down the final siding today. I have a temporary mockup of a tunnel set up in the upper left corner, but I think I'm going to pick up some plastic tunnel portals and set them up before I decide how long the tunnel is going to be.
I'm thinking more and more that I should plan this layout with a mind to sell it before I have to move again next year. That said, most prospective buyers will not be a fan of an East Asian setting, so my plan is to have the buildings set up temporarily so they can be switched out by a new owner. This entails building them as modules and leaving flat areas for them to fit into. We'll see how well this plan works!
The platforms for the main station area and the sidings will be pretty generic, though, so I'm going to turn my attention to those next, and set them up attached to the layout.
