An update on its progress … all of the modifications worked out well with only a bit of extra cutting work where the roof of the left-side extension meets up with the rest of the station. A bit of final detailing but otherwise this is essentially ready to be installed on the layout.
One thing that might not yet be obvious is that I cut out some of the platform layers so to make it easier to line up all of the pieces at the four indented sections of the building - only the lowest layer of the platform material was kept and the upper three layers were cut out. I intend to make these into planter areas to add a bit more interest to the model.
