Prototype photos of a National Steel "Jumbo" boxcar?
I am looking for other prototype photos of this car built by National Steel Car company.
NSC Jumbo Boxcar
The National Steel Car Company Jumbo Box car exceeds Plate F clearance and is the latest design that meets industry standards for the shipment of auto parts or other general commodities. With a gross rail load of 286,000 pounds, this car features a welded all-steel, external post construction. Boasting an interior length of 86½ feet, a width of 8 feet, 7 inches and a ceiling height of 15 feet, 4 inches, it has an interior storage capacity that tops out at a stunning 11,384 cubic feet. In addition, there are four rows of rub rails and a nailable steel floor capable of supporting a 50,000-pound forklift (front axle) load. Also provided are seven rack spacers. An important feature is the "zero-protrusion" smooth interior walls that help reduce damage to the load.
