The General Electric Company, from 1925 to 1928, supplied electric
traction equipment for locomotives built by ALCO and powered by
Ingersoll-Rand diesel engines. In 1929 Ingersoll-Rand and GE teamed
up to build their own locomotives. GE still furnished traction
equipment to Alco who now powered their locos with the newly acquired
McIntosh- seymour diesel engines. In 1940 GE and ALCO entered into
the market for large road diesel locomotives. These engines carried
the logo ""ALCO-GE"" and are described under the American Locomotive
Company. In 1953 GE and ALCO terminated their partnership, although
GE still furnished the traction equipment. At this time GE entered
the large road locomotive market on their own and in 1960 introduced
the U-25b which proved a success in the market place and launched GE
as the #2 builder of diesel locomotives in the USA. Currently GE is
the leading manufacturer of diesel locomotives in the world.
