High Quality Content by WIKIPEDIA articles! Volvat is a disused rapid transit station on the Oslo T-bane. The underground station was located between Majorstuen and Borgen, and opened in 1939. The platform length was only large enough to accommodate two cars. When the Røa Line was upgraded to metro standard on 5 February 1995, it started bypassing Volvat. Finally, as of 7 April 1997 the station was taken out of service when the Kolsås Line trains were extended from two to three cars.
