Norm, you really missed a unique piece of freight equipment in Rich's naval gun and flatcar combo. The 16-in gun is for a Colorado Class Battleship. I talked with Rich at Strasburg several years ago, wondering if it would handle my min 72-in curves and not tear out my catenary poles. He showed me how the Navy designed it to handle tight clearances/tight curves on the real railroads. I was satisfied with his explanation/demonstration and bought it. A beautiful piece of craftsmanship. When I run 1930s era on CONUS Lines, it's always the piece that gets the most attention from visitors...along with the perennial question, "Why was that locomotive built backwards?" (SP Cab-forward)
Two images: First, the gun leaves Ellison Yard, westbound for Long Beach Naval Shipyard. Second, a cab-forward working hard, helps a consist, including the gun, through Cumberland. There is another cab-forward on point.
