what is it?
The VR Class Ds1 Also known as "Puumotti" (Roughly translated to Wood Cubic meter "motti" being a means to measure wood volume) was the first railbus of the Finnish State Railways. It was ordered in 1927. The Ds1 was built by the Pasila workshop, but the automotive parts including the engine were supplied by the Swedish company DEVA. Ds1 has a diesel engine and an electric drive, with a diesel generator providing power to the wheels.
