VR Class Sr1
The Sr1 is a class of electric locomotives built for VR (Finnish railways). These 25kV 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.

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"). In 1970, Valtionrautatiet ordered 27 electric locomotives from Energomachexport, which were delivered between September 1973 and the end of the year 1975. 82 additional locomotives were ordered and delivered between 1973 and 1985. The first prototype locomotive, number 3000, was bought from the constructor in 1994 by VR, which rebuilt it into number 3112.

The locomotives originally carried a dark red livery, with light yellow stripes around and below the cab windows. The stripes were later replaced with yellow warning panels (resembling stylised wings) below the cab windows. From the early 1990s onwards this livery was replaced by an off-white livery with red stripes. Nowadays the locomotives are refitted with a white-green livery to go with the current company colours.

Electrical equipment for the locos was supplied by the Finnish company Oy Strömberg Ab (later part of ABB). Locomotives number 3098-3110 were rebuilt with new bogies allowing a higher maximum speed (160 km/h) in the 1990s (3111 and 3112 were originally built for this speed), but since 2003 they have been restored back to the original top speed due to the speed being raised at the expense of tractive effort (possibly the delivery of the faster Sr2 class also had an effect). The last Sr1 to be equipped with bogies allowing 160 km/h was number 3107.

Two Sr1 class locomotives have been damaged beyond repair and withdrawn from service: number 3048 in Jokela in 1996 and number 3089 in Jyväskylä in 1998. Five other locomotives have also been involved in accidents, but have been rebuilt or repaired afterwards.

Mäntyharju is a municipality of Finland, it is located in the province of Eastern Finland and is part of the Southern Savonia region.

The summer houses or cottages located in the countryside are part of the culture of Finland where most Finnish families spend their summer holidays. Mäntyharju is the municipality which has the fifth most summer houses in Finland. Some of the reasons for Mäntyharju's popularity involves its many pure lakes and a relatively short distance to Helsinki. Because of the many summer houses, population of Mäntyharju more than doubles during the most popular summer holiday times.

Art Centre Salmela in Mäntyharju hosts one of Finland's largest cultural events in July-August. The municipality is unilingually Finnish.

VR or VR Group (Finnish: VR-Yhtymä Oy, Swedish: VR-Group Ab) is a state-owned railway company in Finland. Formerly known as Suomen Valtion Rautatiet (Finnish State Railways) until 1922 and Valtionrautatiet / Statsjärnvägarna (State Railways) until 1995. Its most important function is the operation of freight and passenger rail services.

Since 2010, the maintenance and the construction of the railway network are the responsibility of the Finnish Transport Agency (Finnish: Liikennevirasto). The operation and network were originally carried out by the parent company Valtionrautatiet until 1995, when it was split into VR Group and the rail administration entity Ratahallintokeskus.

VR operated steam locomotives until 1975; the regular use of steam traction for scheduled passenger services ended in 1970 but occasional use continued until 1975. As of 2011, the company operates two classes of electric locomotives (Sr1 and Sr2) and three classes of diesel locomotives (Dv12, Dr14 and Dr16). The use of diesel locomotive hauled passenger trains has declined due to electrification of all main lines and the (re)introduction of railbuses (Dm12) on secondary routes. In October 2010, VR announced plans to renew its locomotive fleet by ordering around 200 new locomotives, which are expected to enter service in 2015-2025.
