. 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. The company changed its name to Alco Products, Incorporated in 1955. In 1964, the Worthington Corporation acquired the company. The company went out of business in 1969.

trainsets followed by production-design locomotives for passenger and freight service. ALCo provided motive power for the Rebel streamliners in 1935, but remained focused on low-power applications while General Motors (owner of EMC) was developing reliable diesel power for full-size mainline trains. In 1939, ALCo started production of passenger diesel locomotives to compete with those produced by EMC. The following year, ALCo entered into a partnership with General Electric ( Alco-GE), for much-needed support in its efforts to compete 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

GE entered the export road-diesel locomotive market in 1956.

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. ALCo closed its Schenectady locomotive plant later that year, and sold its designs to the
