Union Pacific FEF Series : ウィキペディア英語版 | Union Pacific FEF Series
The FEF was a series of three steam locomotive types owned and operated by the Union Pacific Railroad. The classes were: FEF-1; FEF-2; FEF-3. "FEF" was an acronym for the wheel arrangement, "four-eight-four." ==Origins== During the late 1930s, the rising trainloads started to exceed the limits of the then in use 4-8-2's, which were the mainstay of the UP passenger operations. One day, in 1937, with UP President William Jeffer's business car in the rear, a "7000" Class 4-8-2 demonstrated the lack of steaming power inherent in the type. Even when the train was waiting for rescue, dialog by telegram was sent to Alco in Schenectady, with a view of something better. The result was a superb class of forty-five locomotives.
