Finland had five locomotives of class Hr11, which were fitted with two Maybach MD325 engines each rated at 600hp. As far as I can guess (Finnish is not a language I know!) all were built in 1955 and numbered 1950-1954. The transmission is quoted on the "Keski Rahkonen" site as being two Mekydro KL640's. I'm guessing that at least one has been preserved or set aside for preservation as there are recent pictures on each of these links. If anyone has any information, I'd be pleased to accept it!
