Fellestunnelen or Common Tunnel, sometime called Common Line is the part of the subway tunnel under the city of Oslo, Norway that is shared between all the lines on Oslo T-bane. It stretches from Majorstuen in the west to Tøyen in the east, a total distance of 4.8 km.[1]
The Common Tunnel is the bottleneck of the subway system. East of Stortinget there is a capacity of 28 trains per hour while there is a capacity for 24 trains per hour west of Stortinget. This capacity is fully utilised in rush hour, and when the new MX3000 trains are delivered a higher capacity will be introduced on Grorudbanen and Furusetbanen, though the extra trains will terminate at Stortinget.[2]
[edit] History
Majorstuen had been constructed as the terminus for Holmenkollbanen when it opened in 1898 as a tram line. The western part of the Common Tunnel was built in 1928, taking Holmenkollbanen to Nationaltheatret station, as the first underground urban rail line in Scandinavia. The eastern part of the Common Tunnel opened in 1966 when the new T-bane network on the east side of town opened with a terminus at Jernbanetorget. The tunnel was expanded from Jernbanetorget to Sentrum in 1977, and in 1987 a tunnel was built from Nationaltheateret to Sentrum, then renamed Stortinget. The two networks, east and west, were not compatible, as the western system operated on overhead wire while the eastern system had third rail electrification. This was solved by 1993 when Sognsvannsbanen and the Common Tunnel were rebuilt to third trail and some trains were equipped with both pantograph and third rail connectors.[3]
[edit] Stations
The station Valkyrie plass, located between Majorstuen and Nationaltheateret, was closed in 1985.
