The EMD SDL39 is a model of 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division between March 1969 and November 1972. Power was provided by the EMD 645E3 12-cylinder engine as used in the EMD GP39 which generated 2,300 horsepower (1.7 MW). The unit was built on a short 55-foot-2-inch (16.81 m) frame with C-C export trucks, barely tipping the scales at 250,000 pounds (110,000 kg) and managing a light-footed axle-loading of just 20.8 short tons (18.6 long tons; 18.9 t) per axle.

All 10 examples of this locomotive model were built for Milwaukee Road, who wanted a lightweight road-switcher [2] to replace their fleet of ALCO RSC-2s. [3]

These Milwaukee Road units were numbered 581–590. The 581 was wrecked at Sacred Heart, MN in 1983, and scrapped the following year. The remaining nine units were transferred to the Soo Line Railroad when it acquired the Milwaukee Road. All were subsequently included in the sale of the Soo's Lakes States Division (most of its network in Wisconsin and Upper Michigan, plus some lines in adjoining Illinois and Minnesota) to the new Wisconsin Central Limited. After the Wisconsin Central was purchased by, and merged into the Canadian National Railway, the nine units were returned to the lessor, and were sold to FEPASA, Chilean Freight Operation Concession.[ citation needed ]

<span class="mw-page-title-main">EMD E9</span> Model of 2400 hp American passenger cab locomotive

The E9 is a 2,400-horsepower (1,790 kW), A1A-A1A passenger train-hauling diesel locomotive built by General Motors' Electro-Motive Division of La Grange, Illinois, between April 1954 and January 1964. 100 cab-equipped A units were produced and 44 cabless booster B units, all for service in the United States. The E9 was the tenth and last model of EMD E-unit and differed from the earlier E8 as built only by the newer engines and a different, flusher-fitting mounting for the headlight glass, the latter being the only visible difference. Since some E8s were fitted with this, it is not a reliable way to distinguish the two. The E9 has two 1,200 hp (895 kW), V12 model 567C engines, each engine driving one generator to power two traction motors.

<span class="mw-page-title-main">EMC EA/EB</span>

The EMC EA/EB is an early passenger train-hauling diesel locomotive built from May 16, 1937, to 1938 by Electro-Motive Corporation of La Grange, Illinois for the Baltimore and Ohio Railroad. They were the first model in a long line of passenger diesels of similar design known as EMD E-units. Each locomotive unit developed 1,800 horsepower (1,300 kW) from two 900 hp (670 kW) Winton 201-A diesel engines, driving the wheels through an electric transmission—the generator driven by each engine provided current for traction motors. The locomotives were of A1A-A1A wheel arrangement—two three-axle trucks of which only the outer two axles were powered. Six two-unit 3,600 hp (2,700 kW) locomotives were produced, each consisting of a lead cab-equipped EA A unit and a cabless booster EB B unit. They were numbered 51 through 56; the A units bore the bare number and the B units the number followed by 'X'.

<span class="mw-page-title-main">EMD F-unit</span> Line of diesel-electric locomotives

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. They were sold to railroads throughout the United States, Canada and Mexico, and a few were exported to Saudi Arabia. The term F-unit refers to the model numbers given to each successive type, all of which began with the letter F. The F originally meant "fourteen", as in 1,400 horsepower (1,000 kW), not "freight". Longer EMD E-units for passenger service had twin 900-horsepower (670 kW) diesel engines. The E meant "eighteen" as in 1,800 horsepower (1,300 kW). Similarly, for early model EMD switchers, S meant "six hundred" and N meant "nine hundred horsepower".

It succeeded the F7 model in GM-EMD's F-unit sequence. Final assembly was at GM-EMD's La Grange, Illinois plant. The F9 was also built in Canada by General Motors Diesel at their London, Ontario plant. A total of 101 cab-equipped lead A units and 156 cabless booster B units were built. The F9 was the fifth model in GM-EMD's highly successful "F" series of cab unit diesel locomotives.
