The Atchison, Topeka and Santa Fe Railway, often referred to as the Santa Fe or AT&SF, was one of the largest Class 1 railroads in the United States.
A cowl unit is a diesel locomotive with full-width, enclosing bodywork, similar in appearance to the cab unit-style of earlier locomotives, such as the EMD F-units of the 1940s and 1950s. The term cowl unit is of North American origin, although similarly-styled locomotives exist elsewhere.
The EMD F40PH is a four-axle 3,000–3,200 hp (2.2–2.4 MW) B-B diesel-electric locomotive built by General Motors Electro-Motive Division in several variants from 1975 to 1992. Intended for use on Amtrak's short-haul passenger routes, it became the backbone of Amtrak's diesel fleet after the failure of the EMD SDP40F. The F40PH also found widespread use on commuter railroads in the United States and with VIA Rail in Canada. Additional F40PH variants were manufactured by Morrison-Knudsen and MotivePower between 1988 and 1998, mostly rebuilt from older locomotives.
The EMD DDA40X is a 6,600 hp (4,943 kW) D-D locomotive, built by EMD from 1969 to 1971 exclusively for the Union Pacific Railroad. It is the most powerful diesel-electric locomotive model ever built on a single frame, having two 16-645E3A diesel prime movers. Union Pacific has marked DD40X on the cab exteriors, while EMD literature inconsistently refers to this model as either DD-40X or DDA40X.
In North American railroad terminology, a cab unit is a railroad locomotive with its own cab and controls.
The ALCO PA was a family of A1A-A1A diesel locomotives built to haul passenger trains. The locomotives were built in Schenectady, New York, in the United States, by a partnership of the American Locomotive Company (ALCO) and General Electric (GE) between June, 1946 and December, 1953. Designed by General Electric's Ray Patten, they were of a cab unit design; both cab-equipped lead A unit PA and cabless booster B unit PB models were built. While externally the PB models were slightly shorter than the PA model, they shared many of the same characteristics, both aesthetically and mechanically. However, they were not as reliable as EMD E-units.
The EMD SD40 is an American 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division between January 1966 and August 1972. 1,268 locomotives were built between 1966 and 1972. In 1972, an improved version with new electronics was developed and marketed as a new locomotive, the SD40-2.
An SDP40 is a 6-axle passenger diesel-electric locomotive built by General Motors Electro-Motive Division (EMD) between June 1966 and May 1970.
The SD45 is a six-axle diesel-electric locomotive class built by General Motors Electro-Motive Division between 1965 and 1971. It has an EMD 645E3 twenty-cylinder engine generating 3,600 hp (2,680 kW) on the same frame as the SD38, SD39, SD40, and SDP40. As of 2023, most SD45s have been retired, scrapped or rebuilt to SD40-2 standards.
The EMD SD45-2 is a 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division (EMD). EMD built 136 locomotives between 1972 and 1974, primarily for the Atchison, Topeka and Santa Fe Railway (ATSF). The SD45-2 was an improved version of the EMD SD45; the primary visual difference is the absence of flared radiators on the SD45-2.
The EMD F45 is a C-C cowled diesel-electric locomotive built by General Motors Electro-Motive Division between 1968 and 1971. Power was provided by an EMD 645E3 20-cylinder engine which generated 3,600 hp (2,680 kW).
The EMD SDP40F was a six-axle 3,000 hp (2.2 MW) C-C diesel–electric locomotive built by General Motors Electro-Motive Division (EMD) from 1973 to 1974. Based on Santa Fe's EMD FP45, EMD built 150 for Amtrak, the operator of most intercity passenger trains in the United States. Amtrak, a private company but funded by the United States government, had begun operation in 1971 with a fleet of aging diesel locomotives inherited from various private railroads. The SDP40F was the first diesel locomotive built new for Amtrak and for a brief time they formed the backbone of the company's long-distance fleet.
The EMD SD40A is a model of diesel-electric locomotive built by General Motors Electro-Motive Division between 1969 and 1970. 18 locomotives were built for the Illinois Central Railroad.
The Santa Fe CF7 is an EMD F-unit railroad locomotive that has had its streamlined carbody removed and replaced with a custom-made, "general purpose" body in order to adapt the unit for switching duty. All of the conversions were performed by the Atchison, Topeka & Santa Fe Railway's Cleburne, Texas, workshops between February 1970 and 1978. This was Santa Fe's most notable remanufacturing project, with 233 completed between 1970 - March 1978. The program was initiated in response to a system-wide need for more than 200 additional four-axle diesel road switchers to meet projected motive power demands on branch lines and secondary main lines.
The FM H-12-44TS was a light road switcher version of the Fairbanks-Morse H-12-44 yard switcher locomotive. Only three of the 1,200-horsepower (890 kW), six-cylinder opposed piston engine locomotives were manufactured especially for the Atchison, Topeka and Santa Fe Railway in May, 1956. The units had an extended frame to accommodate the addition of a short hood behind the cab, and were configured in a B-B wheel arrangement and mounted atop a pair of two-axle AAR Type-A switcher trucks with all axles powered. H-12-44TSs also came equipped with steam generator units as they were acquired solely for shuttling passenger cars in and around the Dearborn Station terminal in Chicago, Illinois.
The GE U28CG was a dual-service diesel-electric locomotive produced in 1966 by GE Transportation Systems and derived from their freight-hauling U28C design. The sole customer was the Atchison, Topeka and Santa Fe Railway, which ordered ten early that year for delivery in July and August.
The GE U30CG was a passenger-hauling diesel-electric locomotive built by GE Transportation Systems. It was a passenger variant of GE's U30C design purchased by the Atchison, Topeka and Santa Fe Railway. ATSF had purchased ten U28CG locomotives in 1966, and while these locomotives were satisfactory operationally, the railroad felt that their utilitarian appearance was unsuitable for its passenger trains. Desiring smooth-sided passenger power, the railroad ordered the first cowl units from both GE and GM-EMD. GE produced the U30CG to meet this requirement. It was mechanically identical to a U30C except that the bodywork was replaced with a full-width long hood with fluted stainless-steel panels, and a full-width rounded nose and slanted cab front were fitted.
The Museum of the American Railroad, formerly known as the Age of Steam Railroad Museum, is a railroad museum in Frisco, Texas. The museum has more than 70 pieces of steam, diesel, passenger, and freight railroad equipment sitting on 15 acres making it one of the largest historic rail collections in the US. Guests may walk through some of the equipment on guided tours.
The Great Plains Transportation Museum is a railroad museum in Wichita, Kansas, United States.
The Southern California Railway Museum, formerly known as the Orange Empire Railway Museum, is a railroad museum in Perris, California, United States. It was founded in 1956 at Griffith Park in Los Angeles before moving to the former Pinacate Station as the "Orange Empire Trolley Museum" in 1958. It was renamed "Orange Empire Railway Museum" in 1975 after merging with a museum then known as the California Southern Railroad Museum, and adopted its current name in 2019. The museum also operates a heritage railroad on the museum grounds.
