Finnish electric locomotive Sr1 Sr1 is the first electric locomotive of Finland. Maximum speed is 140 km/h. It has continous power rating of 3100 kW, one hour output of 3280 kW and unoffical power rating (1500V wagon electricity counted too) of about 5000 kW. Electric supply is 25 kV 50 Hz ac overhead wire. Traction motors are 4 DC /820 kW/motor (offical), controlled by Strömberg-manufactured (former Finnish company, nowadays part of ABB) thyristor power rectifier drive. It was ordered from USSR, mainly because of political reasons. 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 From the early 1990s onwards this livery has been replaced by a white livery with red stripes.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. Two Sr1 class locomotives have been damaged beoynd repair, number 3048 in an accident in Jokela in 1996 and number 3089 in an accident in Jyväskylä in 1998. There is a total 110 Sr1-class locomotives in service today. More information of locomotive: http://www.kotimaki.com/rautatie/rsto... http://en.wikipedia.org/wiki/VR_Class...
