N-scale steam scenes small room layout

Steam scenes. Views of Sheol Mine, the A. Bawl Breaker (abandoned), the Border Colliery, and a Lacky/Reading steam meet on the bridge over the Crimea River. 1954 eastern Pennsylvania anthracite country. Reading, Jersey Central, Pennsylvania, Lehigh Valley, LNE and others all run in this industrial spaghetti bowl. Lower deck is dual track double-loop and a single track single loop. Upper deck goes back a few years and is all steam on a single loop, with a connection to the Lehigh Valley. All in an enclosed 9' x 12' room complete with HVAC. Decks connect by a single loop around-the-room 'helix'. Duck-under entry, the trains run around the operator, and are often out of sight behind strategic view blocks. Multiple ambient sound systems. Yep, still all DC block wired!
