This hole in the wall would become a passenger terminal, with building fronts to cover up the mess.
I kitbashed a passenger station using two platicville airplane hangers and an HO powerplant. I still have to finish the right side along the wall. Not sure what I will do there. There are industrial sidings on the lower level, so I will have to blend industrial, the passenger station and maybe smaller scale housiing or buildings etc in HO and N scale.
The platform is a standard covered platform extension, with a few additional uncovered sections made from foam food platters, carved with a hot foam knife tool to match the sidewalk markings. I couldn't find the disney station, which would have made a great clock tower addition
