GSC Heavy Duty Flat Car
Prototype Information
General Steel Castings (GSC) began producing heavy-duty depressed center flatcar castings in the 1940s. These cars handled massive loads like transformers and industrial machinery. GSC lowered the center deck to just above the rails to clear low bridges and tunnels. This design allowed railroads to carry much taller equipment than standard flatcars. GSC sold these one-piece castings as kits, usually including 3-axle Commonwealth trucks. Some railroads chose to use Buckeye trucks instead during assembly.
The extreme weight of 125-ton loads required a specialized dual braking system. Crews installed a main control valve on the B end and an auxiliary valve on the A end. All braking hardware sat inside the car frame for protection, while external piping connected the two systems. Each end of the car featured its own air reservoir and hand brake. This setup ensured that brake shoes pressed against all twelve wheels to stop the heavy-tonnage freight safely.
