 EMD emerged from the war years with major advantages for over competitors in diesel locomotive production, having entered them with fully developed lines of mainline road diesel locomotives while war production allocations restricted their competitors, principally the American Locomotive Company (ALCO) and the Baldwin Locomotive Works, to selling mainly diesel switchers and steam locomotives of pre-existing designs.That gave an advantage to EMD's state of technical development with higher powered diesels in the critical postwar years.New model passenger locomotives were delivered starting in February 1945.
