From 1940 to 1953 ALCO and GE jointly marketed diesel locomotives.
In 1955 the American Locomotive Company changed its name to
Alco Products Inc. to emphasize the diversification of products
manufactured. In 1969 Alco terminated domestic locomotive production
and sold the locomotive designs to the
Montreal Locomotive Works which
Alco had bought control of in 1904.
