An EMD SDL39 is a 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division between March 1969 and November 1972. Power was provided by an EMD 645E3 12-cylinder engine which generated 2,300 horsepower (1.7 MW). All 10 examples of this locomotive model were built for Milwaukee Road, who wanted a lightweight road-switcher to replace their fleet of 1947-built ALCO RSC-2s. 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.

The EMD SDL39 is practically an experimental, lightweight version of the SD39, but uses a GP38's body and frame with the SD39's engine.

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 leaser, and were sold to FEPASA, Chilean Freight Operation Concession.
