Locomotives built or sold by the Westinghouse Electric Company
Westinghouse's transportation division (rail equipment) was founded 1894 and sold to AEG 1988, later merged into Adtranz and Bombardier. Production of locomotives ended after the early 1950s.
Usually built in partnership with the Baldwin Locomotive Works, see Baldwin-Westinghouse electric locomotives.
Early examples built in partnership with William Beardmore and Company (Beardmore) of Glasgow, Scotland.
In addition, Westinghouse produced and supplied electrical and traction equipment for Baldwin diesel locomotives from 1939 to 1955 and Lima-Hamilton diesels from 1949-1951 until production at Lima, Ohio ended with the merger into Baldwin. Fairbanks-Morse diesels also used Westinghouse electrical and traction equipment.
