The American Locomotive Company (often shortened to ALCO, ALCo or Alco) was an American manufacturer that operated from 1901 to 1969, initially specializing in the production of locomotives but later diversifying and fabricating at various times diesel generators, automobiles, steel, tanks, munitions, oil-production equipment, as well as heat exchangers for nuclear power plants.
The company was formed by the merger of seven locomotive manufacturers and Schenectady Locomotive Engine Manufactory of Schenectady, New York. A subsidiary, American Locomotive Automobile Company, designed and manufactured automobiles under the Alco brand from 1905 to 1913. ALCO also produced nuclear reactors from 1954 to 1962.[2] After World War II, Alco closed all of its manufacturing plants except those in Schenectady and Montreal.
In 1955, the company changed its name to Alco Products, Incorporated. In 1964, the Worthington Corporation acquired the company. The company went out of business in 1969,[1] although Montreal Locomotive Works continued to manufacture locomotives based on Alco designs.
Alco built many of the biggest locomotives ever constructed, including Union Pacific's Big Boy (4-8-8-4). Alco also built the fastest American locomotives, the Class A Atlantic and Class F7 Hudson streamliners for the Milwaukee Road's Twin Cities Hiawatha run. Among the ambitious state-of-the-art designs of the late steam era, Alco's Challengers, Big Boys, and high-speed streamliners stood out for their success in operations.
Alco built the second production steam locomotive in North America to use roller bearings (after the Delaware & Hudson's 1924 addition of SKFroller bearings to the drivers and main and side rods of their own 4-6-2 locomotives). This was Timken 1111, a 4-8-4 commissioned in 1930 by Timken Roller Bearing Company and ultimately used for 100,000 miles (160,000km) on 15 major United States railroads before it was purchased in 1933 by the Northern Pacific Railway. The Northern Pacific renumbered the Four Aces to No. 2626 and ran it on the North Coast Limited, as well as its pool trains between Seattle, Washington, and Portland, Oregon, and excursions, through 1957.
During World War II, Alco produced many 2-10-0 Decapods for the USSR. Many went undelivered, and ten of these were sold to Finland in 1947. One, Alco builder's No. 75214, is preserved at the Finnish Railway Museum.[7]
Though the dual-service 4-8-4 steam locomotive had shown great promise, 1948 was the last year that steam locomotives were manufactured in Schenectady. These were the seven A-2a class 9400-series Pittsburgh & Lake Erie Railroad2-8-4 "Berkshires." Their tenders had to be subcontracted to Lima Locomotive Works, as Alco's tender shop had been closed. The building was converted to make diesel locomotives to compete with those of the Electro-Motive Division of General Motors.[8]
Joseph Burroughs Ennis (1879–1955) was a senior vice president between 1917 and 1947 and was responsible for the design of many of the company's locomotives.
Alco automobiles (1906-1913)

The company diversified into the automobile business in 1906, producing French Berliet designs under license. Production was located at Alco's Rhode Island Locomotive Works in Providence, Rhode Island. Two years later, the Berliet license was abandoned, and the company began to produce its own designs instead. An Alco racing car won the Vanderbilt Cup in both 1909 and 1910 and competed in the first Indianapolis 500 in 1911, driven on all three occasions by Harry Grant.[9]
ALCO's automotive venture was unprofitable, and they abandoned automobile manufacture in 1913.[9] The Alco automobile story is notable chiefly as a step in the automotive career of Walter P. Chrysler, who worked as the plant manager. In 1911 he left Alco for Buick in Detroit, Michigan, where he subsequently founded the Chrysler Corporation in 1925.
Electric locomotives
Alco made 60-ton center-cab electric freight motors from 1912 through the 1920s for electric railway lines in Oregon.[10]
The company bought the McIntosh & Seymour Diesel Engine Company in 1929 and henceforth produced its own diesel engines, though it always bought its electrical equipment from GE. The diesel program was largely overseen by Perry T. Egbert, vice president in charge of diesel locomotive sales and later president of the company.[11]
In the early to mid-1930s, ALCo was the pre-eminent builder of diesel-electric switch engines in the United States. It was slower than its competition to develop reliable diesel power for full-size mainline trains, though it did provided motive power for the Gulf, Mobile and Northern Railroad's Rebel streamliners in 1935.
In 1939, ALCo started producing passenger diesel locomotives to compete with General Motors' Electro-Motive Corporation. The following year, ALCo teamed up with General Electric (Alco-GE) for much-needed support in competing with EMC. In 1941, ALCo introduced the RS-1, the first road-switcher locomotive. The versatile road-switcher design gained favor for short-haul applications, which would provide ALCo a secure market niche through the 1940s. The entry of the United States into World War II froze ALCo's development of road diesel locomotives.
During that time, ALCo was allocated the construction of diesel switching locomotives, their new road-switcher locomotives, a small quantity of ALCO DL-109 dual-service engines and its proven steam designs, while EMD (formerly EMC) was allocated the construction of mainline road freight diesels (the production of straight passenger-service engines was prohibited by the War Production Board). Still, ALCo ranked 34th among United States corporations in the value of wartime production contracts.[12]
Alco's RS-1 road switcher was selected by the United States Army for a vital task: rejuvenating the Trans-Iranian Railway and extending it to the Soviet Union. This gave the U.S. ally a new supply line at a time when the German air force and navy had reduced Allied shipments to the Soviet port of Murmansk. The U.S. Army chose as locomotives the RSD-1, a six-axle, six-traction motor variant of the light ALCo RS-1. Not only was the company prevented from selling these locomotives to mainline U.S. railroads, but the 13 RS-1s that had already been built were commandeered for Iranian duty and converted to RSD-1s.[8]
Post-war era
The postwar era saw ALCo's steam products fall out of favor while it struggled to develop mainline diesel locomotives competitive with EMD's E and F series road locomotives, which were well-positioned from GM-EMC's large development efforts of the 1930s and its established service infrastructure. ALCo would prove unable to overcome that lead.
In 1946, ALCo controlled 26% of the diesel locomotive market.[11] The ubiquitous S series (660 and 1000 horsepower) switchers and RS series (1000 and 1500 horsepower) road switchers represented ALCo well during the late 1940s. Much of its success in this period can be tied to its pioneering RS locomotives, representing the first modern road-switcher, a configuration which has long-outlasted ALCo. The success of their switcher and road-switcher locomotives was not matched with the PA and FA-type mainline units, however.
The 244 engine, developed in a crash program to compete with EMD's powerful 567 engine, proved unreliable and sales of ALCo's mainline units soon went into decline. In 1948, ALCo-GE produced a prototype gas turbine-electric locomotive to address the concerns of operators such as Union Pacific that sought to minimize the number of locomotive units needed for large power requirements. In 1949, ALCo embarked on a clean-sheet design project to replace the 244. 1949 also saw the introduction of the EMD GP7 road-switcher, a direct challenge in ALCo's bread-and-butter market.
In 1953, General Electric, dissatisfied with the pace of ALCo's efforts to develop a replacement for the troubled 244 engine, dissolved their partnership with ALCo and took over the gas turbine-electric venture that had started series production the previous year. In 1956, ALCo made long-overdue changes, modernizing its production process and introducing road locomotives with its new 251 engine. However, the benefits to ALCo were negated by bad timing; the market for locomotives was declining after the height of the dieselization era and EMD's GP9 was on the market as a proven competitor backed by a service infrastructure that ALCo, since the dissolution of the GE partnership, lacked. Sales were disappointing and ALCo's profitability suffered.[11]
GE entered the export road-diesel locomotive market in 1956, then the domestic market in 1960, and quickly took the No. 2 position from ALCo, and eventually eclipsed EMD in overall production. Despite continual innovation in its designs (the first AC/DC transmission among others), ALCo gradually succumbed to its competition, in which its former ally, General Electric, was an important element.[8]
India during 1960s began gradual withdrawal of Steam locomotives from Indian Railways so the Diesel electric locomotive WDM series was developed by Banaras Locomotive Works with help of American Locomotive Company (ALCO) for Indian Railways. In 1962 Alco locomotives entered in service and since then Thousands of Alco class Locomotive WDM-2, WDM-3A , WDM-3D would be manufactured and rebuilt which would make most successful locomotives of Indian Railways serving both passenger and freight trains and still retain operational status for Indian railways today[13][14]
A new line of Century locomotives including the 630 (the first AC/DC transmission), the 430 and the 636, the first 3,600 horsepower (2.7 MW) locomotive, failed to keep the enterprise going. Third-place in the market proved to be an impossible position; ALCo products had neither the market position nor reputation for reliability of EMD's products, nor the financing muscle and customer support of GE. It could not earn enough profits. In the late 1960s, Alco gradually ceased locomotive production, shipping its last two locomotives, a pair of T-6 switchers to the Newburgh & South Shore Railroad (#1016 and #1017) in January 1969.[8] ALCo closed its Schenectady locomotive plant later that year, and sold its designs to the Montreal Locomotive Works in Canada. The vast ALCo Schenectady plant was completely demolished by 2019, and its site is now occupied by a large industrial park.
Diversification
Alco diversified into areas other than automobiles with greater success. During World War II, Alco built munitions for the war effort, in addition to locomotive production; this continued throughout the Korean War. After the Korean War, Alco began making oil production equipment and heat exchangers for nuclear plants.
In 1955, the company was renamed Alco Products, Incorporated. By this stage, locomotive production only accounted for 20% of the business.[15][16]
The first nuclear power plant connected to the electrical grid, the SM-1, was built for the Army Nuclear Power Program at Fort Belvoir in Virginia in 1957.[17] Another complete plant, the PM-2A, was shipped to and constructed at Camp Century in Greenland. The Camp Century plant was filmed by the U.S. Army.[18]
Purchase and division
The company was purchased in 1964 by the Worthington Corporation, which merged with the Studebaker corporation in 1967 to form Studebaker-Worthington, Alco remaining a wholly owned subsidiary.[19] Former divisions of Alco became semi-independent subsidiaries in 1968.
After the termination of locomotive production in 1969, the locomotive designs (but not the engine development rights) were transferred to the Montreal Locomotive Works, which continued their manufacture. The diesel engine business was sold to White Motor Corporation in 1970, which developed White Industrial Power.[20] In 1977 White Industrial Power was sold to the British General Electric Company (GEC) which renamed the unit Alco Power. The business was subsequently sold to the Fairbanks-Morse corporation, which continues to manufacture Alco-designed engines in addition to their own design.
The heat exchanger business continued as Alco Products for a time. At some later point, some of the heat exchanger products were manufactured by the Alco Products Division of Smithco Engineering in Tulsa, Oklahoma (Smithco). In January 1983, certain assets of the Alco Products Division of Smithco, namely double-pipe and hairpin-type heat exchanger products sold under the "Alco Twin" name, mark and style, were sold in an asset sale by Smithco to Bos-Hatten, a subsidiary of Nitram Energy. Following the sale of these assets, Smithco remained in business, manufacturing other heat exchange products. In 1985, the assets acquired from Smithco were assigned by Bos-Hatten to its parent, Nitram. In 2008, Nitram was acquired by Peerless Manufacturing Co[21] In 2015, Peerless sold its heat exchanger business to Koch Heat Transfer Co.[22]
Epilogue

After the closure of Alco's Schenectady works, locomotives to Alco designs continued to be manufactured in Canada by Montreal Locomotive Works and in Australia by AE Goodwin.
In addition, Until 2022, Alco-derived locomotives accounted for most of the diesel power on the Indian Railways.[23] Many thousands of locomotives with Alco lineage are in regular mainline use in India. Most of these locomotives were built by the Diesel Locomotive Works (DLW) at Varanasi, India. The Diesel Loco Modernisation Works (DMW) at Patiala, India, do mid-life rebuilding and upgrading the power of these locomotives, typically the 2,600 horsepower (1.94MW)WDM-2 to 3,100 horsepower (2.31MW).

A number of Alco and MLW diesel-electric locomotives (models DL500C, DL532B, DL537, DL543, MX627 and MX636) are in daily use hauling freight trains of the Hellenic Railways Organisation (OSE) in Greece. The oldest of them (class A.201, DL532B) were delivered to the former Hellenic State Railways (SEK) in 1962. In addition to a variety of standard gauge locomotives, the fleet includes 11 metre gauge Alco locomotives, mainly used for departmental trains in the Peloponnese network. The MX627 and MX636 locomotives have been extensively rebuilt at Piraeus Central Factory of OSE. The remaining Alco locomotives are also being rebuilt, starting with models DL532B and DL537.
ALCO-Cooke 2-8-0 #18, built in 1920, survives in passenger service on the Arcade & Attica Railroad in Arcade, New York. It returned to service in May 2009 after a six-year overhaul to bring it into compliance with the FRA's new steam locomotive regulations.
Some Alcos survive on Australian networks, as well as in Bangladesh and Pakistan. Another fleet of Alco Bombardier locomotives run in rugged terrain on the Sri Lanka railway network. Argentina also has a healthy fleet of Alcos DL540 running commuter and cargo trains.
The Glenbrook Vintage Railway New Zealand, has a 2-4-4-2 articulated compound mallet, built by Alco in 1912. Only four mallets with this wheel arrangement were ever built; the other three by Baldwin. This unique loco is currently out of service awaiting overhaul.
During the 1970s, Romania's UCMR Resita made licensed engines from ALCo, putting the engines 6&12R251 into naval gensets and also with the 6R251 in FAUR factory were made locomotives known as LDH 1500 CP. (CFR Classes 67/68/70/71 and CFR Class 61). They were also exported in Iran and Greece (OSE)
Another, preserved, Alco-built locomotive, is a 2-10-0 construction number 75506/1947 (local name Ty246), stored at Zduńska Wola Railway Museum, Poland.[27][28]
In Spain an Alco 2-3-0 locomotive built 1916 (Construction number: 57068) is displayed at the Ceutaold Station.[29]
In February 2014, in the episode The Locomotive Manipulation of the TV series The Big Bang Theory, takes place on a train pulled by what is described as an "Alco FA-4".
Noted railroad artist Howard L. Fogg began his career at Alco. Hired in 1946 as Alco's new company artist, Fogg began painting locomotives in the livery of prospective customers and taking photographs of them.
At an Alco gala at the Waldorf Astoria Hotel, Lucius Beebe, a noted journalist with the New York Herald-Tribune, sought out Fogg. Beebe was considering leaving New York to write railroad books. They began a long-term collaboration, with Beebe buying Fogg's paintings and commissioning new ones for use in his books. In 1947, Beebe's book, Mixed Train Daily, was the first of many to use a Fogg painting on the cover. Fogg was also used by many other railroad authors because of his skill at capturing action shots. With commissions from individuals, authors, publishers, railroads, and related industrial firms flourishing, in 1957 Fogg ended his formal agreement with Alco. He continued to paint periodic commissions for them for a number of years.

A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel-electric locomotives and diesel-hydraulic.
Baldwin Locomotive Works (BLW) was an American manufacturer of railway locomotives from 1825 to 1951. Originally located in Philadelphia, Pennsylvania, it moved to nearby Eddystone in the early 20th century. The company was for decades the world's largest producer of steam locomotives, but struggled to compete when demand switched to diesel locomotives. Baldwin produced the last of its 70,000-plus locomotives in 1951, before merging with the Lima-Hamilton Corporation on September 11, 1951, to form the Baldwin-Lima-Hamilton Corporation.
GE Transportation is a division of Wabtec. It was known as GE Rail and owned by General Electric until sold to Wabtec on February 25, 2019. The organization manufactures equipment for the railroad, marine, mining, drilling and energy generation industries. The company was founded in 1907. It is headquartered in Pittsburgh, Pennsylvania, while its main manufacturing facility is located in Erie, Pennsylvania. Locomotives are assembled at the Erie plant, while engine manufacturing takes place in Grove City, Pennsylvania. In May 2011, the company announced plans to build a second locomotive factory in Fort Worth, Texas, which opened in January 2013.
Montreal Locomotive Works (MLW) was a Canadian railway locomotive manufacturer that existed under several names from 1883 to 1985, producing both steam and diesel locomotives. For many years it was a subsidiary of the American Locomotive Company. MLW's headquarters and manufacturing facilities were in Montreal, Quebec.
The GE U25B is General Electric's first independent entry into the United States domestic road switcher diesel-electric locomotive railroad market for heavy production road locomotives since 1936. From 1940 through 1953, GE participated in a design, production, and marketing consortium (Alco-GE) for diesel-electric locomotives with the American Locomotive Company. In 1956 the GE Universal Series of diesel locomotives was founded for the export market. The U25B was the first attempt at the domestic market since its termination of the consortium agreement with Alco.
The EMD BL2 is a model of diesel-electric locomotive built by General Motors Electro-Motive Division (EMD). A total of 58 units were built between 1947 and 1949. The BL2 was not very successful, as it was unreliable and occupied a gap between carbody and hood units, which resulted in it suffering from the drawbacks of both designs. However, lessons learned from the BL2 were incorporated into EMD's next design, the GP7.
General Motors Diesel was a railway diesel locomotive manufacturer located in London, Ontario, Canada. It was established in 1949 as the Canadian subsidiary of the Electro-Motive Diesel division of General Motors (EMD). In 1969 it was re-organized as the "Diesel Division of General Motors of Canada, Ltd." The plant was re-purposed to include manufacture of other diesel-powered General Motors vehicles such as buses. Following the Canada-United States Free Trade Agreement in 1989, all of EMD's locomotives were built at the London facility. In 2005 new owners of EMD renamed the Canadian subsidiary "Electro-Motive Canada". The plant was closed by EMD's new owner Progress Rail in 2012, with EMD's production remaining in LaGrange, Illinois and Muncie, Indiana.
The EMD GP30 is a 2,250 hp (1,680 kW) four-axle diesel-electric locomotive built by General Motors Electro-Motive Division of La Grange, Illinois between July 1961 and November 1963. A total of 948 units were built for railroads in the United States and Canada, including 40 cabless B units for the Union Pacific Railroad.
The ALCO RS-3 is a 1,600 hp (1.2 MW), B-B diesel-electric locomotive manufactured from May 1950 to August 1956 by American Locomotive Company (ALCO) and its subsidiary Montreal Locomotive Works (MLW). A total of 1,418 were produced: 1,265 for American railroads, 98 for Canadian railroads, 48 for Brazilian railroads, and seven for Mexican railroads.
A road switcher locomotive is a type of railroad locomotive designed to both haul railcars in mainline service and shunt them in railroad yards. Both type and term are North American in origin, although similar types have been used elsewhere.
Electro-Motive Diesel is a brand of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. Formerly a division of General Motors, EMD is now owned by Progress Rail, a subsidiary of Caterpillar Inc. Electro-Motive Diesel traces its roots to the Electro-Motive Engineering Corporation, founded in 1922 and purchased by General Motors in 1930. After purchase by GM, the company was known as GM's Electro-Motive Division. In 2005, GM sold EMD to Greenbriar Equity Group and Berkshire Partners, and in 2010, EMD was sold to Progress Rail. Upon the 2005 sale, the company was renamed to Electro-Motive Diesel.
The ALCO RS-1 was a 4-axle diesel-electric locomotive built by Alco-GE between 1941 and 1953 and the American Locomotive Company from 1953 to 1960. ALCO subsidiary Montreal Locomotive Works built an additional three RS-1s in 1954. This model has the distinction of having the longest production run of any diesel locomotive for the North American market. The RS-1 was in production for 19 years from the first unit Rock Island #748 in March 1941 to the last unit National of Mexico #5663 in March 1960.
The ALCO RS-2 is a 1,500–1,600 horsepower (1,100–1,200 kW) B-B 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. Between 1946 and 1950, 377 examples of the RS-2 were built, primarily for American and Canadian customers.
The ALCO FA was a family of B-B diesel locomotives designed to haul freight trains. The locomotives were built by a partnership of ALCO and General Electric in Schenectady, New York, between January 1946 and May 1959. Designed by General Electric's Ray Patten, they were of a cab unit design; both cab-equipped lead FA and cabless booster FB models were built. A dual passenger-freight version, the FPA/FPB, was also offered. It was equipped with a steam generator for heating passenger cars.
The Indian locomotive class WDM-2 is a class of diesel-electric locomotive that was developed in 1962 by American Locomotive Company (ALCO) for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Mixed traffic (M) engine, 2nd generation (2). They entered service in 1962. A total of more than 2,700 WDM-2 was built at ALCO and Banaras Locomotive Works, Varanasi between 1962 and 1998, which made them the most numerous class of mainline diesel locomotive until its successor the WDM-3A.
The ALCO DL560C is a series of diesel-electric locomotive with AC electric transmission designed by the American Locomotive Company and produced under license by Banaras Locomotive Works (BLW) Varanasi, India for Indian Railways as their classes WDM-2, WDM-3A/2C, WDM-3D and WDG-3A for operation in India. The locomotive is fitted with a 16-cylinder ALCO 251 B,C diesel engine. In the early 1960s Indian Railways needed a reliable diesel workhorse to gradually replace its steam locomotive fleet. Equal numbers of ALCO's DL560C and EMD's G16 were chosen for trials. More locomotives of each of these were purchased for more trials. Indian Railways was keen on producing these locomotives in the country rather than depending on imports. EMD did not agree for a Transfer-of-Technology, while ALCO did. Thus ALCO DL560C was chosen for the job due to its easy maintenance, reliability and simple operation. And from then on vast numbers of this loco in different configurations have been produced and remain the main diesel traction power of Indian Railways.
Maine Central Railroad began operating diesel locomotives in 1935, and had retired all steam locomotives by 1954. That time interval was a joint operating period with the Boston and Maine Railroad (B&M). This article describes diesel locomotives owned by Maine Central through the period of joint operation and later independent operation prior to Guilford Rail System control in 1981.
The Indian locomotive class WDM-4 is a class of diesel-electric locomotive that was developed in 1962 by Electro-Motive Diesel for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Mixed traffic (M) engine, 4th generation (4). They entered service in 1962. A total of 72 WDM-4 locomotives were built between 1961 and 1962.
The Indian locomotive class WDM-3A is a class of diesel–electric locomotive that was developed in 1993 by Banaras Locomotive Works (BLW), Varanasi for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Mixed traffic (M) engine, with 3300 horsepower (3A). The WDM-3A is a later classification of earlier WDM-2C. They entered service in 1994. A total of 143+ were built at ALCO and Banaras Locomotive Works between 1994 and 2003 with rest of the 1246 units being rebuilt from WDM-2 which made them the most numerous class of mainline diesel locomotive until the WDG-4.
The Indian locomotive class WDM-3D is a class of diesel-electric locomotive that was developed in 2003 by Banaras Locomotive Works (BLW), Varanasi for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Mixed traffic (M) engine with 3300 horsepower (3D). The engine is classified WDM-3D though it outputs only 3300 hp and not 3400 hp as the name should suggest. They entered service in 2003. A total of 590+ WDM-3D were built at Banaras Locomotive Works (BLW), Varanasi between 2003 and 2016.
