The Baldwin 0-6-6-0-1000/1DE were cab unit diesel-electric locomotives 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.
