The Baldwin 0-6-6-0-1000/1DE is a cab unit diesel-electric locomotive built by Baldwin Locomotive Works in 1945.
The 0-6-6-0-1000/1DEs were powered by an eight-cylinder diesel engine rated at 1,000 horsepower (746 kW), and rode on a pair of three-axle trucks in a C-C wheel arrangement.
30 of these models were built for Soviet Railways, today Russian Railways, as Class Дб (Class Db).
None survived to preservation, however the cab of one of the locomotives is known to have survived as a shed, and a bogie is known to have been used underneath a fuel tanker.
