The FM H-12-44 was a yard switcher produced by Fairbanks-Morse from May, 1950–March, 1961. The units featured a 1,200-horsepower (890 kW), six-cylinder opposed piston engine prime mover, and were configured in a B-B wheel arrangement mounted atop a pair of two-axle AAR Type-A switcher trucks, with all axles powered and geared for a top speed of 60 miles per hour (97 km/h).
A total of 303 units were built for American railroads, 30 were manufactured (between August 1951 to June 1956) by the Canadian Locomotive Company for use in Canada, and 1 unit was exported to Mexico. Initially, H-12-44s were visually indistinguishable from their predecessor model, the FM H-10-44. However, beginning in September, 1952 the Raymond Loewy design elements were removed as a cost-saving measure: cab lines were squared-off, the slanted-nose styling was discontinued, and the roof visor was eliminated. The following year, the fairing over the battery box was removed and louvers added to reduce the possibility of battery explosions. None of the units were produced between May and October 1956, after which time the carbodies were shortened by some three feet and outfitted with a deeper side skirt.
Sixteen intact examples of the H-12-44 are known to survive today, all of which are owned by railroad museums or historical societies.
One FM H-12-44TS, Santa Fe 543, now resides at the Illinois Railway Museum.

Several examples of the H-12-44 model have been preserved around the US and Canada.
Under the Whyte notation for the classification of steam locomotives, 4-8-4 represents the wheel arrangement of four leading wheels on two axles, eight powered and coupled driving wheels on four axles and four trailing wheels on two axles. The type was first used by the Northern Pacific Railway, and initially named the Northern Pacific, but railfans and railroad employees have shortened the name when referring to the type, and now is most commonly known as a Northern.
The Atchison, Topeka and Santa Fe Railway, often referred to as the Santa Fe or AT&SF, was one of the larger railroads in the United States. The railroad was chartered in February 1859 to serve the cities of Atchison, Kansas, Topeka, Kansas, and Santa Fe, New Mexico. The railroad reached the Kansas–Colorado border in 1873 and Pueblo, Colorado, in 1876. To create a demand for its services, the railroad set up real estate offices and sold farmland from the land grants that it was awarded by Congress.
The U28C road switcher locomotive was developed by General Electric from the U25C, with a slight increase in power of 300 hp (224 kW). A passenger-hauling variant, the U28CG, was also produced for the Atchison, Topeka and Santa Fe Railway.

The EMD NW2 is a 1,000 hp (750 kW), B-B switcher locomotive manufactured by General Motors Electro-Motive Division of La Grange, Illinois. The NW2 was manufactured from February 1939 to December 1949, and 1145 were produced – 1121 for the U.S., and 24 were exported to Canada. Starting in late 1948 the NW2s were manufactured in EMD's Plant #3 in Cleveland, Ohio. The 1,000 hp (750 kW) was achieved by using a 12-cylinder, model 567, and later, a model 567A engine. In addition, 3 TR cow-calf paired sets, 36 TR2 cow-calf paired sets, and 2 TR3 cow-calf-calf sets were produced. The TR sets were built prior to World War II and the TR2 and TR3 sets were built postwar.
The H-24-66, or Train Master, was a diesel-electric railroad locomotive produced by Fairbanks-Morse and its licensee, Canadian Locomotive Company. These six-axle hood unit road switchers were deployed in the United States and Canada during the 1950s.

The EMD GP7 is a four-axle (B-B) road switcher diesel-electric locomotive built by General Motors Electro-Motive Division and General Motors Diesel between October 1949 and May 1954.
The EMD SD45-2 is a 6-axle road switcher diesel-electric locomotive built by General Motors Electro-Motive Division (EMD). EMD built 136 locomotives between 1972–1974, 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 lack of flared radiators on the SD45-2.
The Baldwin S-12 was a 1,200-horsepower (890 kW) diesel-electric locomotive intended for use in yard switching. Utilizing a turbocharged 6-cylinder version of the powerful 606A diesel prime mover, S-12s were known for their "lugging" power, despite being temperamental. Like most Baldwin switchers, the S-12 had AAR Type-A switcher trucks in a B-B wheel arrangement. 451 units were built between 1951 and 1956, when Baldwin left the locomotive market.
The ALCO RS-2 is a 1,500–1,600 horsepower (1,100–1,200 kW) B-B road switcher diesel-electric locomotive built by the American Locomotive Company (ALCO) from 1946 to 1950. ALCO introduced the model after World War II as an improvement on the ALCO RS-1. The locomotive was one of several road switchers in a crowded market, including the Baldwin DRS-4-4-1500, EMD GP7, and FM H-15-44. ALCO discontinued the RS-2 in 1950 in favor of the ALCO RS-3. Several examples have been preserved.
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 "Beep" is an individual switcher locomotive built in 1970 by the Atchison, Topeka and Santa Fe Railway at its Cleburne, Texas, workshops. Technically a rebuild, the Beep originally entered service on the Santa Fe as a Baldwin Model VO-1000. Following its successful CF7 capital rebuilding program, the company hoped to determine if remanufacturing its aging, non-EMD end cab switchers by fitting them with new EMD prime movers was an economically viable proposition. The conversion procedure proved too costly and only the one unit was modified. In 2008-2009, this locomotive was retired and stored operational at Topeka, Kansas. In May 2009 the unit was donated to the Western America Railroad Museum in Barstow, California.
The Baldwin VO-1000 is a diesel-electric locomotive (switcher) built by Baldwin Locomotive Works between January 1939 and December 1946. The 236,260–242,200 lb (107,170–109,860 kg) units were powered by a normally aspirated eight-cylinder diesel engine rated at 1,000 horsepower (746 kW), and rode on a pair of two-axle trucks in a B-B wheel arrangement. These were either the AAR Type-A switcher trucks, or the Batz truck originally developed by the Atchison, Topeka and Santa Fe Railway as a leading truck for steam locomotives. 548 examples of this model were built for American railroads, including examples for the Army and Navy.
The FM H-12-44TS was a light road switcher version of the Fairbanks-Morse H-12-44 yard switcher. 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 FM H-10-44 was a yard switcher produced by Fairbanks-Morse from August, 1944–March, 1950. The units featured a 1,000-horsepower (750 kW), six-cylinder opposed piston prime mover, and were configured in a B-B wheel arrangement mounted atop a pair of two-axle AAR Type A trucks, with all axles powered. Many H-10-44s received modifications that increased their horsepower rating to 1,200 hp (890 kW).
The FM H-16-44 was a road-switcher produced by Fairbanks-Morse from April 1950 – February 1963. The locomotive shared an identical platform and carbody with the predecessor Model FM H-15-44, and were equipped with the same eight-cylinder opposed piston engine that had been uprated to 1,600 horsepower (1,200 kW). The H-16-44 was configured in a B-B wheel arrangement, mounted atop a pair of two-axle AAR Type-B road trucks with all axles powered. In late 1950, the AAR trucks were almost exclusively replaced with the same units found on the company's "C-liner" locomotives.
The FM H-20-44 was a multiple unit-capable end cab road switcher manufactured by Fairbanks-Morse from June 1947 – March 1954, and represented the company's first foray into the road switcher market. The 2,000 hp (1,490 kW), ten-cylinder opposed piston engine locomotive was referred to by F-M's engineering department as the "Heavy Duty" unit. It was configured in a B-B wheel arrangement mounted atop a pair of two-axle AAR Type-B road trucks with all axles powered. H-20-44s shared the same platform and much of the same carbody as the lighter-duty FM H-15-44, which began its production run three months later.
The Texas Transportation Museum (TTM) is a transportation museum located near San Antonio, Texas, USA.
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 the Pinacate Station as the "Orange Empire Trolley Museum", and moved to its current site in Perris 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.
