The VR Class Hr11 was the first class of diesel locomotives used by Valtionrautatiet (Finnish State Railways). Only five units were built all delivered by Valmet in 1955. The Maybach diesel engines used in the locomotives proved highly unreliable resulting in a complete overhaul of the engine-transmission system in 1956-58 but this did not solve all reliability problems. The Hr11 series was withdrawn from service in 1972.
