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 have been 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. Rail transport started in Finland in 1862, and multiple main lines were built at the end of the nineteenth and the beginning of the twentieth century in addition to smaller private railways. Valtion Rautatiet operated mainly on the bigger and longer main lines. During the twentieth century, most private railway companies were shut down and Valtionrautatiet assumed a monopoly in rail transport. In 1995 the company was privatised into VR group.
