The Baldwin DT-6-6-2000 (Also referred to as the Baldwin DT6-6-2000) was a twin-engined diesel-electric transfer locomotive, built by Baldwin Locomotive Works between 1946 and 1950. A single prototype using a pair of 8 cylinder nominally aspirated 608NA prime movers (engines) was built in 1946 for the Elgin, Joliet and Eastern Railway. In order to minimise the length of the locomotive, the crosswalks at the ends of the locomotives were omitted. This feature was not repeated in the subsequent locomotives. Forty-five further locomotives were built using 6-cylinder turbocharged 606SC prime movers during 1948–1950.
