The first Challengers were conceived in 1936 as fast freight engines to replace the Union Pacific's fleet of three cylinder 4 12 2 locomotives. With an extra center cylinder for added power and a top speed of 45 mph, the 4 12 2s had been successful freight engines when built in 1926. But a decade later they were considered slow and difficult to maintain.
