context_page_description: The Grünerløkka–Torshov is a tramway line running from Jernbanetorget to Storo in Oslo, Norway. It is served by lines 11, 12 and 13 of the Oslo Tramway.
  The line was built by Kristiania Sporveisselskap and opened for horsecars in 1878 from Stortorvet to Grünerløkka, and was extended on 12 April 1879 to St. Halvards Plass. Electrification occurred in 1899, with a further extension to Grefsen Station in 1902. In 1934 the new Kjelsås Line was built branching off from Storo to Kjelsås.
