The Lionel EMD F3A-F3B Diesel Locomotives Northern Pacific is a set of two locomotives, an "A" and "B" Unit. Back in the 1940s-1960s when cab units were common running pairs of "A" and "B" units was typical for rail operations. The EMD F3 was a cab type diesel locomotive introduced by the ElectroMotive Division of General Motors in July 1945. With World War II production restrictions lifted, and railroads anxious to move from steam to diesel, the F2 arrived just in time. The EMD 567B prime mover produced 1,500 hp- the F3 differed from the F2 with the addition of the D12 generator that provided more power. EMD built 1,111 "A" units and 696 "B" Units between 1945-49- making the F3 EMD's the second most produced model in the "F" Series.
Historical Fact: The North Coast Limited, inaugurated by Northern Pacific in 1900, was their crack passenger train from Chicago (via the Burlington) to the Pacific Northwest. In the Postwar Period F3s would be a common sight on these fast trains.
