Section 1: Active Major Builders/Rebuilders
Section 2: Inactive Major Builders/Rebuilders
Section 3: Minor Builders/Rebuilders


This list includes information on diesel-electric, diesel-hydraulic, gasoline-electric, gasoline-hydraulic, LNG-electric, gas turbine and electric locomotives intended for use by railroads in North America. I intend to exclude locomotives built for export only or for industrial use. Also excluded are export designs used in North America and standard North American designs built for export. I have included notes about industrial locos, since they will be seen here and there, but not in-depth information. Some electric locomotives have also been included.

Each locomotive builder or rebuilder is included, along with a brief history of the company, types of engines used, locations of the major shops and a detailed list of locomotive models produced. Model number, dates built, number built and brief comments are included. Homebuilt locos, some rebuilds from railroads' own shops, rebuilds done on only a few units, and most contract rebuildings are not included. Contract rebuilds and rebuilds by railroads' shops are listed where they involve a very major upgrade, i.e. conversion from freight to passenger service, new prime mover, and/or where the locomotive is considered to be "new" after the rebuild. There are exceptions, usually for what I consider to be 'important' locomotive programs. Notes in [brackets] apply to all models below the note. Unofficial designations or identifying symbols for units without official models are in single quotes (i.e. 'SD40X', 'Zephyr'). In the Baldwin, F-M and Alco sections I have dropped the first (often only) hyphen in each designation for the sake of simplicity.

The hundreds of GP7U, GP8, GP9U, GP10 and GP16 rebuilds from GP7/9/18s are not listed, because those rebuilds were little more than heavy overhauls when compared with recent rebuilds (i.e. GP28M, SD40M-2). Also, railroad programs to upgrade SD40s and 45s to -2 standards are generally not included, since these upgrades are/were usually done in railroad shops in the course of normal overhauls.

General Motors Locomotive Group (GMLG)

GMLG is a new name for the business unit controlling two very old GM divisions, EMD and GMDD. GM was the unquestioned leader in the diesel locomotive field for many years, but their number one position was taken by GE in 1983. Electromotive Division (EMD): EMD was formed by the 1930 purchase (by GM) of railcar builder Electro Motive Corporation (EMC) and engine builder Winton Engine. The EMC name was retained until the two companies were merged to become EMD in 1941. Engines: 201-A early non-turbo engine, 600 HP (8 cyl.) to 1200 HP (16 cyl.) 8x10 inch cylinder 567 non-turbo, 600 HP (6 cyl.) to 1350 HP (16 cyl.) 567A non-turbo, same HP as 567 567B non-turbo, 600 HP (6 cyl.) to 1500 HP (16 cyl.) 567BC non-turbo update/modification of 567B 567C non-turbo, 600 HP (6 cyl.) to 1750 HP (16 cyl.) 567C supercharged, 2000 HP (16 cyl.) 567D1 non-turbo, 1325 HP (12 cyl.) to 1800 HP (16 cyl.) 567D2 turbocharged, 2000 HP (16 cyl.) 567D3 turbocharged, 2250-2400 HP (16 cyl.) 567D3A turbocharged, 2500 HP (16 cyl.) all 567: 8.5x10 inch cylinder 645E non-turbo, 1000 HP (8 cyl.) to 2000 HP (16 cyl.) 645E3 turbocharged, 1500 HP (8 cyl.) to 3600 HP (20 cyl.) 645E3A turbocharged, 3300 HP (26 cyl.) to 4200 HP (20 cyl.) 645F turbocharged, 2600-2800 HP (12 cyl.) to 3500-3600 HP (16 cyl.) all 645: 9.0625x10 inch cylinder 710G turbocharged, 2800-3200 HP (12 cyl.) to 5000 HP (20 cyl.) 9.0625x11 inch cylinder H turbocharged, 6000 HP max Shops: LaGrange (McCook), Ill (component construction only; partially closed) Chicago, Ill (closed) Cleveland, OH (closed) General Motors Diesel Division (GMDD): General Motors Diesel, Ltd. (GMDL) was created in Canada in 1950, later becoming GMDD. Now does all GM locomotive building work, and has sub-contracted some assembly work to Conrail's Juniata shops, Canadian Pacific's Ogden Shops, VMV Paducah, and some to a plant near Mexico City, Mexico. Shops: London, Ontario Super Steel Schenectady: A division of GM formed in 1995 to build new locomotives for LIRR. Shops: A new plant built at Glenville, New York.

General Electric

GE started out producing electrical components for locomotives built be other companies and at various points teamed up with other builders (notably Alco) to build locomotives. In 1960 they introduced the U25B to the domestic market, and now are the number one builder North America. GE purchased the Alco/MLW shop in Montreal, using it primarily for -S7 rebuilds. It was later closed. GE also owned the ex E-L Hornell, NY shops for several years, using it for Alco rebuilds and two F7A overhauls. The shop was later sold to MK and is now owned by GEC Alsthom. GE sold to rights to build Alco engines and spare parts, as well as the right to market the engines for all non rail applications, to Fairbanks-Morse in 1994, followed by rail application rights in 1997. Engines: IR--Ingersoll-Rand, various sizes and HP ratings CB--Cooper-Bessemer, various sizes and HP ratings Cat--Caterpillar, various sizes and HP ratings 7FDL--main GE engine, ratings of 2500 HP to 4400 HP with 16 cyls., 1800 to 3200 HP with 12 cyls., 1800 HP with 8 cyls. used in all U series, -7, -S7, -8, -9 and most AC units. 9x10.5 inch cylinder, all turbocharged HDL--new GE engine, ratings up to 6000 HP, used in later AC series Shops: Erie, PA Sayre, PA (ex LV)--railcar shop Montreal, Quebec (ex Alco/MLW plant, now closed) Hornell, NY (ex E-L plant, closed and sold to MK, then GEC Alsthom) Recently some assembly work has been subcontracted to Conrail (NS) Juniata Shops. *B-B Switchers '44 Ton' ?/40-?/56 348 Cat engine '60 Ton' ?/24 1 IR engine '60 Ton' ?/28-?/30 2 IR engine '60 Ton ?/31 7 IR engine '70 Ton' ?/46-?/58 238 CB engine two built as narrow gauge C-C units '95 Ton' ?/49-?/56 47 CB engine '100 Ton' ?/28-?/30 11 IR engine 'dual power' ?/30 45 IR engine variety of diesel-electric/battery and diesel-electric/battery/third rail units 'ERIE 925' ?/31 1 IR engine 'DEY-2' ?/36 5 CB engine 'Model Y' ?/36 5 IR engine 'Center Cab' ?/33-?/35 7 IR engine 'Center Cab' ?/37-?/40 9 CB engine 'Center Cab' ?/39-?/40 4 CB engine 'Center Cab' ?/41 2 CB engine '128 Ton' ?/43-?/45 3 CB engine SL80 11/76- 5+ Still in production?

MotivePower Industries

(formerly Morrison Knudsen Rail Corp.) Morrison-Knudsen was formed in 1915 by Harry Morrison and Morris Knudsen. The company made a name in all sorts of heavy construction and engineering projects, with work ranging from rebuilding Tehachapi Pass after the disastrous earthquake of 1952 to building a special barge to lay a tunnel under Boston Harbor a few years ago to building subway, Amtrak and commuter rail cars to building and rebuilding locomotives. In 1971 the company opened its Boise Locomotive Shop in Idaho. In the 1980's M-K purchased from GE the ex Erie-Lackawanna shops at Hornell, NY for railcar work, and in 1989 M-K opened the Boise Truck & Engine Annex and the Mountaintop, PA Locomotive Shop. In 1994 the rail operations were split off as the Morrison Knudsen Rail Corp. and the hyphen was dropped from the corporate name. Effective 1 January 1997 Morrison Knudsen Rail Corp. became MotivePower Industries. The Boise Locomotive Shop became Boise Locomotive Company, and MK Engine Systems Company, the engine subsidiary, became Engine Systems Company. MK/MPI's specialty has long been rebuilding and upgrading older units to -2 standards. They have done hundreds of SD40-2 and SD40M-2 rebuilds and dozens of "F40 substitutes", all rebuilt from older units. When EMD refused to modify its F40PH-2C design to suit MBTA's needs, MK built its first new locomotives, near clones of EMD F40PH-2C. MK built two locomotives of its own design, the MK1200G and the MK1500D. The MK1500D became the MP1500D under MPI; new models included MP2000D (2000 HP version) and MP2000C (2000 HP C-C version). Engines: MPI uses EMD 645E and 645E3 engines in most rebuilds. M-K used imported Sulzer engines in several rebuilds, but they proved unreliable and the effort was abandoned. Alco 251 series engines were also used.

American Locomotive Company (ALCo)

American Locomotive Company was one of the steam locomotive builders in the country, and gradually switched over to diesels. The name of the company was changed to Alco in 1956. Alco's name and assets were acquired by Worthington in 1964, and Worthington merged with Studebaker Studebaker-Worthington in 1967. Alco quit building locomotives in 1969. Alco's longtime subsidiary Montreal Locomotive Works purchased the rights to Alco designs in 1969. MLW was sold to Bombardier Company in 1979. All Alco rights were eventually sold to GE, and then to Fairbanks-Morse (Coltec) in 1997. In 1998 Coltec sold the locomotive parts business and locomotive rights to National Railway Equipment (NRE), but Coltec retains the rights to the Alco engines themselves. Later in 1998 NRE and Coltec/F-M formed Alco Locomotive Company, a new business intended to market all Alco spare parts (both new and reconditioned), and rebuilt Alco locomotives.

Montreal Locomotive Works

MLW was Alco's longtime Canadian subsidiary. MLW built both Alco designs (tabulated in the Alco section) and its own designs, listed here. MLW (MLW-Worthington) acquired the rights to Alco designs in 1969. MLW-W acquired Bombardier in 1976, becoming Bombardier-MLW. The name was changed to Bombardier in 1978. MLW built its last locomotives in September 1984. The shop was then leased to GE for several years and now stands empty. Engines: MLW used Alco engines in all its products, including the first, last and only North American 18 cylinder engine in the M640. Shops: Montreal, Quebec.

BLW was one of the biggest steam locomotive builders, and, like ALCo, gradually switched over to diesels. In 1950 Baldwin purchased Lima-Hamilton and discontinued the Lima-Hamilton product line. Baldwin-Lima-Hamilton stopped building locomotives in 1956. The Eddystone plant was demolished in 1995.
