It's not even the station that's spectacular, although that IS cool. It's the way you have it elevated above, and have the tracks below, and what I assume are dummy tracks next to the active ones, and a tunnel underneath. Amazing.
Thanks PDX. Necessity really is the mother of all invention. In an approx 8x15 room, expansion is either vertical or via a hole through the wall into the next room. The wife won’t stand for the latter, so vertical it is. Counting the floor, I’m now working with four levels (elevated, mainline, subway, and floor).
