The EMD F7 is a model of 1,500-horsepower (1,100 kW) diesel-electric locomotive produced between February 1949 and December 1953 by the Electro-Motive Division of General Motors (EMD) and General Motors Diesel (GMD).
Diesel Electric locomotives (DEs) develop their rated HP at any speed whereas steam develops it at only one speed. Why? Let us look at the physics.
6 lip 2006 · It’s the famous “bulldog nose” that did it. It hit the road with FT demonstrator quartet 103, “the diesel that did it”-i.e., sealed the steam locomotive’s doom with its 1939-40 coast-to-coast 83,764-mile, 20-railroad, 35-state tour.
EMD F-units are a line of diesel-electric locomotives produced between November 1939 and November 1960 by General Motors Electro-Motive Division and General Motors-Diesel Division. Final assembly for all F-units was at the GM-EMD plant at La Grange, Illinois, and the GMDD plant in London, Ontario.
The EMD F7 is a model of 1,500-horsepower (1,100 kW) diesel-electric locomotive produced between February 1949 and December 1953 by the Electro-Motive Division of General Motors (EMD) and General Motors Diesel (GMD).
The All-American F7 defined railroading during the 1950s; nearly every notable Class 1 operated at least one and many rostered dozens, or even hundreds, of these locomotives. When one pictures Electro-Motive's classic streamlined diesels, the F7 most often comes to mind.
The F7s were one of EMD's most popular locomotives, with over 3600 units being constructed for most American railroads. While the original FT may have been the "diesel that did it," it was the F7 that put steam power to rest on many railroads, including the Reading.
