Looks like a bunch of brick structures and a lot of kitbashing.
Yeah, I'm most daunted by the depot because of the mix of brick patterns. I think the freight house will be plaster castings. The difficulty of the tower lies solely on whether I use pre-made windows and doors.
I can make a foobie station from the Pella depot like Dave did. Give it a new roof with no overhang, square of the bay and add a bit for the baggage area and I can live with that for a while.
I'll still be hitting you up for an etch of the train order semiphore. I'll draw it into CAD when I get a chance.
