Atchison, Topeka & Santa Fe EMD FP45 No. 90 rests at the Corwith Yard engine facility near Chicago, Illinois, on September 1, 1991. These EMD cowl locomotives were built at the request of Santa Fe, who wanted to replace old F units used on its passenger trains, and desired a locomotive at least somewhat “streamlined”. Originally built as AT&SF No. 100 in December 1967, it soon went from passenger into freight service with the coming of Amtrak in 1971, and quickly don freight locomotive colors and number series. With Super Fleet Warbonnet colors returning to the Santa Fe in 1989, the burly engine was again returned to a shiny coat red and silver, and numbered 100. But the stardom was short-lived with the coming of new EMD GP60Ms in the 100-series in 1990; it was briefly again renumbered 5990 and at long last No. 90. The historic locomotive was finally retired at the hands of BNSF on January 14, 1999, and donated to the Oklahoma Railroad Museum in 2000.
