In 1962 General American Corp. started to build their most popular insulated boxcar designs, a refinement of their proven 1950s design. One of the major developments for the car design and unique to General America was its all welded body construction, where only the roof was bolted on after insulation. These CADILLACs of the boxcar market were insulated, had 20-inch cushioned underframes, and a variety of load restraining devices per customer specifications.
