Common Tunnel
The Common Tunnel ( no, Fellestunnelen), sometimes called the Common Line (), is a long tunnel of the Oslo Metro which runs through the city center of Oslo, Norway. The name derives from the fact that all five lines of the metro use the tunnel, which runs from Majorstuen to Tøyen. The section has six stations, including the four busiest on the metro. The tunnel was first built as two separate tunnels which were later connected. The Holmenkolbanen company opened the western section of the tunnel from Majorstuen via Valkyrie plass to Nationaltheatret in 1928. In 1966, the Oslo Metro opened, including the tunnel from Tøyen via Grønland to Jernbanetorget. In 1977, the eastern end was extended to Sentrum, but the extension was closed in 1983 because of water leakages. In 1987, the Sentrum station reopened as Stortinget, and became the terminus of both the western and eastern lines. By 1993, the western end had been upgraded to metro standard, Valkyrie plass was closed, and th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ring Line (Oslo)
The Ring Line ( no, T-baneringen or ) is the newest rapid transit loop line of the Oslo Metro of Oslo, Norway. It connects to the Sognsvann Line in the west and the Grorud Line in the east; along with these two lines and the Common Tunnel, the Ring Line creates a loop serving both the city centre and Nordre Aker borough. The -long line has three stations: Nydalen, Storo and Sinsen. Four-fifths of the line runs within two tunnels, with the section between Storo and Sinsen, including both stations, being the only at-grade part. The line connects to the Grorud Line north of Carl Berners plass and with the Sognsvann Line north of Ullevål stadion. Planning for the line began in the late 1980s, and the city council approved the line 1997. Construction started in 2000; Nydalen and Storo opened on 20 August 2003, and Sinsen opened on 20 August 2006. The line cost to build and was financed through Oslo Package 2.

Headway
Headway is the distance or duration between vehicles in a transit system measured in space or time. The ''minimum headway'' is the shortest such distance or time achievable by a system without a reduction in the speed of vehicles. The precise definition varies depending on the application, but it is most commonly measured as the distance from the tip (front end) of one vehicle to the tip of the next one behind it. It can be expressed as the distance between vehicles, or as time it will take for the trailing vehicle to cover that distance. A "shorter" headway signifies closer spacing between the vehicles. Airplanes operate with headways measured in hours or days, freight trains and commuter rail systems might have headways measured in parts of an hour, metro and light rail systems operate with headways on the order of 90 seconds to 20 minutes, and vehicles on a freeway can have as little as 2 seconds headway between them. Headway is a key input in calculating the overall route cap ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Double Track
A double-track railway usually involves running one track in each direction, compared to a single-track railway where trains in both directions share the same track. Overview In the earliest days of railways in the United Kingdom, most lines were built as double-track because of the difficulty of co-ordinating operations before the invention of the telegraph. The lines also tended to be busy enough to be beyond the capacity of a single track. In the early days the Board of Trade did not consider any single-track railway line to be complete. In the earliest days of railways in the United States most lines were built as single-track for reasons of cost, and very inefficient timetable working systems were used to prevent head-on collisions on single lines. This improved with the development of the telegraph and the train order system. Operation Handedness In any given country, rail traffic generally runs to one side of a double-track line, not always the same side a ...

Oslo Metro Map
Oslo ( , , or ; sma, Oslove) is the capital and most populous city of Norway. It constitutes both a county and a municipality. The municipality of Oslo had a population of in 2022, while the city's greater urban area had a population of in 2019, and the metropolitan area had an estimated population of in 2021. During the Viking Age the area was part of Viken. Oslo was founded as a city at the end of the Viking Age in 1040 under the name Ánslo, and established as a ''kaupstad'' or trading place in 1048 by Harald Hardrada. The city was elevated to a bishopric in 1070 and a capital under Haakon V of Norway around 1300. Personal unions with Denmark from 1397 to 1523 and again from 1536 to 1814 reduced its influence. After being destroyed by a fire in 1624, during the reign of King Christian IV, a new city was built closer to Akershus Fortress and named Christiania in honour of the king. It became a municipality (''formannskapsdistrikt'') on 1 January 1838. The city func ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Traffic Bottleneck
A traffic bottleneck is a localized disruption of vehicular traffic on a street, road, or highway. As opposed to a traffic jam, a bottleneck is a result of a specific physical condition, often the design of the road, badly timed traffic lights, or sharp curves. They can also be caused by temporary situations, such as vehicular accidents. Bottlenecks can also occur in other methods of transportation. Capacity bottlenecks are the most vulnerable points in a network and are very often the subject of offensive or defensive military actions. Capacity bottlenecks of strategic importance - such as the Panama Canal where traffic is limited by the infrastructure - are normally referred to as choke points; capacity bottlenecks of tactical value are referred to as mobility corridors. Causes Traffic bottlenecks are caused by a wide variety of things: * Construction zones where one or more existing lanes become unavailable (as depicted in the diagram on the right) * Accident sites that ...

Grorud Line
The Grorud Line ( no, Grorudbanen) is a line on the Oslo Metro between Tøyen and Vestli in Oslo, Norway. Built as a mix of underground, at ground level and as an elevated line, it runs through the northern part of Groruddalen, serving such neighborhoods as Grorud, Romsås and Stovner. Line 5 runs along the entire line four times per hour. Line 4 runs between Vestli and Økern before branching off on the Løren Line to get onto the Ring Line. With 40,000 daily riders, the Grorud Line is the busiest branch of the metro. Proposals for an urban railway through the upper parts of Groruddalen were first articulated in public documents in 1919. Planning started in the late 1940s and the line was politically approved in 1954, along with three other metro lines and the Common Tunnel. Construction started in 1956 and was part of a process to transform Groruddalen into a residential area. The first part of the Grorud Line, from Tøyen to Grorud, was opened on 16 October 1966.

Lambertseter Line
The Lambertseter Line ( no, Lambertseterbanen) is a line on the Oslo Metro which runs from Brynseng to Bergkrystallen. It further shares track with the Østensjø Line along the section from Tøyen to Brynseng. The line runs through a primary residential area of Nordstrand, serving neighborhoods such as Manglerud, Ryen and Lambertseter. The line is served by Line 4 of the metro, which runs every fifteen minutes. This is supplemented by Line 1 that is extended to Bergkrystallen between 6:30 and 19 on weekdays, giving a combined frequency of eight trains per hour. Originally the Lambertseter Line was proposed as an extension of the now closed Simensbråten Line. Planning of a metro started in 1946 and instead of running via Ekeberg the Lambertseter Line was to run via Etterstad. Construction was tied with large-scale construction of housing along the route. As the Lambertseter Line could be completed much earlier than the metro's Common Tunnel, the Lambertseter Line was f ...
