OKRX 48 - SW 8

This engine was built in 1952 by General Motors' Electromotive Division for the US Army. It saw service in Korea during the war as No. 2034. After re-manufacture at Hill Air Force base in September 1987, the locomotive was delivered to the Army Ammunition plant in McAlister, OK, on Nov. 18, 1987.

ATSF 2571 - EMD CF7

This engine was built by GE's Electromotive Division in about 1949 as an F7A, # 202L, a "covered wagon" similar to the Museum's F9A, OKRX 814. In the 1970's, the AT&SF Railroad needed road engines that could also function as switch engines. But, they couldn't afford to buy new locomotives. The railroad had many aging F7's that could be used, but the "covered wagon" body would have made switching work difficult, requiring the engineer to stick his head out of the window to see the end of the train. The AT&SF determined that F7's could be modified to look more like freight engines where the engineer could see well in both directions. The conversions were accomplished in 1972 by the AT&SF at their shops in Cleburne, TX. The modified F7 units were given the new designation of CF7. This locomotive was donated to the ORM in 2012 by the Burlington Northern Santa Fe Railroad. Weight: 249,000 lbs. Fuel capacity: 1250 gal.

ATSF 90 - EMD FP45

The previous owner of this FP45 locomotive was the Atchison, Topeka & Sante Fe Railway, later the BNSF. This engine was built by EMD (Builders No. 33189) in December 1967 as AT&SF (Santa Fe) No. 100. Prime mover: 20 cylinder-645E3, 3600 HP. Right out of the box, No. 100 and its sister, No. 102, had the honor of leading the record-breaking inaugural run of the westbound Super C, a high-priority, 79 mile-per-hour freight train from Chicago to Los Angeles in January 1968. Following this grand entrance, No. 100 settled down to pulling Santa Fe's finest passenger trains. The Santa Fe remained committed to first class passenger trains, even while other railroads were decreasing or completely abandoning passenger service. Nine 3600 hp FP45 locomotives numbered 100-108 were delivered for service on the El Capitan and Super Chief in 1967, painted in the classic red and silver "warbonnet" colors which had graced Santa Fe's diesel passenger locomotives since 1937. This engine was renumbered into the 5940 series along with the rest of the FP45's in March 1970, as part of the 1969/70 general renumbering. With the coming of Amtrak in 1971, the FP45's were reassigned to freight duties for the remainder of their careers, other than occasional use pulling business and special trains. Sometime in late 1971 or early 1972, the 5940's shed their flashy red and silver "warbonnet" for Santa Fe's more mundane blue and yellow freight scheme. Within a few years, they were repainted again into the blue and yellow "warbonnet" scheme. This loco was rebuilt in September 1981. In 1989, it was decided that all new locomotives would be delivered in the red and silver "warbonnet" paint, called the "Super Fleet." The FP45's were repainted into a version of the paint scheme in which they were originally delivered. These locomotives were renumbered several times with Number 90 as the last of its kind in active service on the BNSF railroad before being donated to the ORM by the Burlington Northern Santa Fe Railway in December of 1999. Weight: 399,000 lbs. Fuel capacity: 3200 gal.
