It is manufactured in Novochserkassk Electric Locomotive Works, former USSR.
First locomotives were delivered on year 1973. Last production model from factory was delivered on 1985.
Two additional locomotives were built at the 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.
The locomotives originally carried a dark red livery, with white stripes around and below the cab windows. The stripes were later replaced with yellow warning panels (resembling stylished wings) below the cab windows. From the early 1990s onwards this livery has been replaced by a white livery with red stripes. The nicknames for these locomotives are "Siperian susi" (Wolf of Siberia; it comes from the typical sound of Sr1, when it passes you can heard the "wolf crying" ; in Finnish slang "susi" can also mean a poorly manufactured object.
