Sr1 was the first electric locomotive in Finland. From politic reasons
it was ordered from USSR, but much of its electric parts were built in
Finland by Oy Strömberg Ab, now part of ABB.
Despite its Finnish nick name Siperian Susi (Wolf of Siberia), it
has been reliable. First locomotives were delivered on year 1973. Locomotives
have thyristor made power rectifiers and every axle has dc traction motor.
From year 1995 to 2003
locomotives 3100-3112 had their maximum speed raised to 160 km/h.
