In 1951, General Steel Castings (GSC) provided 42' flat car bodies to the Union Pacific. The Union Pacific assembled these cars in Denver, CO and designated them by the car class F-50-15. The GSC 42’ flat car was purchased to serve the railroad as a general service flat, which means that these cars moved all types of freight. Some were re-classified into more specialized service, including TOFC, wheel service, traction motors, and we have been told that some carried aircraft components.
The car body of GSC flat is cast, which means the entire car body is a single piece of solid steel. The result is that these cars are veritable battleships on rails, and many are in active MoW service today--63 years later!
ExactRail’s GSC flat cars have full underbody detail and laser etched wood decks. They have accurately captures the unique curves of the cast design, which makes these cars so elegant.
