Despite having a low population density, the Government annually spends around €350 million to maintain the  network of railway tracks. Rail transport is handled by the state owned VR Group, which has a 5% passenger market share (out of which 80% are from urban trips in Greater Helsinki) and 25% cargo market share. Since 12 December 2010, Karelian Trains, a joint venture between Russian Railways and VR Group, has been running Alstom Pendolino operated high-speed services between Saint Petersburg's Finlyandsky and Helsinki's Central railway stations. These services are branded as "Allegro" trains. The journey from Helsinki to Saint Petersburg takes only three and a half hours. A high-speed rail line is planned between Helsinki and Turku, with a line from the capital to Tampere also proposed. Helsinki opened the world's northernmost metro system in 1982, which also serves the neighbouring city of Espoo since 2017.
