VR Class Dr12 (original designation Hr12) was a heavy diesel-electric locomotive of Valtionrautatiet (Finnish State Railways). The first 6 locomotives were ordered in 1956. They entered service between 1959 and 1963. The locomotives were built by 2 manufacturers, Valmet and Lokomo, both based in Tampere. All Hr12 class locomotives with even numbers were produced by Valmet, while all odd numbers were produced by Lokomo. The locomotives were withdrawn in the early 1990s.
