The Sr1 is a class of electric locomotives built for VR of Finland. These 25 kV locomotives were built in the Soviet Union at the Novocherkassk Electric Locomotive Factory between 1973 and 1985. Two additional locomotives of this class were built at the VR Hyvinkää Machine Workshop in 1993 and 1995, number 3111 from spare parts and number 3112 from the original prototype locomotive (number 3000) that was never used by the VR.[1] The official classification given by the manufacturer is VL70 or ES40.
The nicknames for these locomotives are "Siperian susi" (Wolf of Siberia; in Finnish slang "susi" can also mean a poorly manufactured object, compare English "dog" or "lemon"),[1] "Kaalihäkki" (Cabbage Cage)[1] and "Sähköryssä" (Electric Russkie).
