Plarail Advance Lego Station

I also plan to cover the table with 3 players of hard pink foam insulation. I may or may not use Plarail subway tunnels. I think it would be cool to have a section on the side that was open, but the foam is meant for me to cut and route the Plarail track. A concern I have is underground access. The subway may just follow the outside of the table and curve back in and go up, go on ground and decend again into the terminal entrance. The station will defiantly have 2 layers, ground level for express and sleeper trains and down for the subway and commuter operations, also with a possible upper level on the side for Shinkansen services.
