Hvalstad Station
Hvalstad Station ( no, Hvalstad stasjon) is a railway station of the Drammen Line located at Hvalstad in Asker, Norway. Situated from Oslo Central Station, it consists of an island platform and serves the L1 line of the Oslo Commuter Rail operated by Vy. The station served 233,000 passengers in 2012. The line opened at the same time as the Drammen Line on 7 October 1872. The first station building was a wooden structure designed by Georg Andreas Bull. The station was moved in 1915 to its current location. This resulted in another wooden station building, designed by Jens Flor. The third station building, designed by Julie Kristiansen, was completed in 1957. This resulted in the station being raised to an elevated structure. Bull's building has been demolished, while Flor's and Kristiansen's have been listed as heritage sites. History Hvalstad was along with Asker Station the only stations to be opened along with the Drammen Line on 8 October 1872.Bjerke & Holom: 189 Th ...

Akershus County Municipality
Akershus County Municipality ( no, Akershus fylkeskommune) was the regional governing administration of the old Akershus county in Norway. The county municipality was established in its most recent form on 1 January 1976 when the law was changed to allow elected county councils in Norway. The county municipality was dissolved on 1 January 2020, when Akershus was merged with the neighboring counties of Buskerud and Østfold, creating the new Viken county which is led by the Viken County Municipality. The administrative seat is located in Oslo (which was not part of Akershus) and the county mayor was Anette Solli. The main responsibilities of the county municipality included the running of the 35 upper secondary schools. It managed all the county roadways, public transport, dental care, culture, and cultural heritage sites in the county. Transport Public transport in Akershus is managed by Ruter, a transit authority owned along with the City of Oslo. It markets all publ ...

Track Circuit
A track circuit is an electrical device used to prove the absence of a train on rail tracks to signallers and control relevant signals. An alternative to track circuits are axle counters. Principles and operation The basic principle behind the track circuit lies in the connection of the two rails by the wheels and axle of locomotives and rolling stock to short an electrical circuit. This circuit is monitored by electrical equipment to detect the absence of the trains. Since this is a safety appliance, fail-safe operation is crucial. Hence the circuit is designed to indicate the presence of a train when failures occur. On the other hand, false occupancy readings are disruptive to railway operations and must be minimized. Track circuits allow railway signalling systems to operate semi-automatically, by displaying signals for trains to slow or stop in the presence of occupied track ahead of them. They help prevent Train dispatcher, dispatchers and Manual block, operators from ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axle Counter
An axle counter is a system used in railway signalling to detect the clear or occupied status of a section of track between two points. The system generally consists of a wheel sensor (one for each end of the section) and an evaluation unit for counting the axles of the train both into and out of the section. They are often used to replace a track circuit. Principles and operation An axle counter consists of the axle counter sensor, which detects the individual axles of a train either via either mechanical, electrical or even fibre optic methods, as well as an evaluator, which does the logic of the system and counts the axles into and out of the section. The evaluator may also convert the analogue signal of the axle counter sensor into a digital signal. However, in some cases there is a separate unit which performs this task. The system is set up by having an axle counter sensor installed at each end of a section. As each train axle passes the axle counter sensor at the start o ...

Centralized Traffic Control
Centralized traffic control (CTC) is a form of railway signalling that originated in North America. CTC consolidates train routing decisions that were previously carried out by local signal operators or the train crews themselves. The system consists of a centralized train dispatcher's office that controls railroad interlockings and traffic flows in portions of the rail system designated as CTC territory. One hallmark of CTC is a control panel with a graphical depiction of the railroad. On this panel, the dispatcher can keep track of trains' locations across the territory that the dispatcher controls. Larger railroads may have multiple dispatcher's offices and even multiple dispatchers for each operating division. These offices are usually located near the busiest yards or stations, and their operational qualities can be compared to air traffic towers. Background Key to the concept of CTC is the notion of ''traffic control'' as it applies to railroads. Trains moving in opposit ...

Automatic Train Stop
Automatic train stop or ATS is a system on a train that automatically stops a train if certain situations occur (unresponsive train operator, earthquake, disconnected rail, train running over a stop signal, etc.) to prevent accidents. In some scenarios it functions as a type of dead man's switch. Automatic train stop differs from the concept of Automatic Train Control in that ATS usually does not feature an onboard speed control mechanism. Overview Mechanical systems The invention of the fail-safe railway air brake provided an external means for stopping a train via a physical object opening a valve on the brake line to the atmosphere. Eventually known as ''train stops'' or ''trip stops'', the first mechanical ATS system was installed in France in 1878 with some railroads in Russia following suit using a similar system in 1880. In 1901 Union Switch and Signal Company developed the first North American automatic train stop system for the Boston Elevated Railway. This system was so ...

Narvesen
Narvesen is a Norwegian chain of newsagents / convenience stores which, with its 370 outlets nationwide, is one of Norway's largest retailers. The company has since 2000 been part of the Reitan Group (''Reitangruppen''). Narvesens Kioskkompagni (the name later shortened to Narvesen) was established by the businessman and merchant Bertrand Narvesen (1860–1939) who in 1894 received approval from Norwegian State Railways to take over the sale of all newspapers, magazines, and travel literature on its stations. Narvesen became a nationwide joint stock company in 1928. Today Narvesen also operates 249 stores in Latvia Latvia ( or ; lv, Latvija ; ltg, Latveja; liv, Leţmō), officially the Republic of Latvia ( lv, Latvijas Republika, links=no, ltg, Latvejas Republika, links=no, liv, Leţmō Vabāmō, links=no), is a country in the Baltic region of ... and a further 260 stores in Lithuania.

Slependen Station
Slependen Station ( no, Slependen holdeplass) is a railway station on the Drammen Line located at Slependen in Bærum, Norway. Situated from Oslo Central Station, it consists of an island platform and serves the L1 line of the Oslo Commuter Rail operated by the Norwegian State Railways. It had 900 daily passengers in 2008. The first station at Slependen was located further west and opened on 11 September 1873, a year after the Drammen Line. It was variously known as Slæbenden and Slæbende until it took its present name in 1921. A new station building was erected in 1916 and demolished in 1960. With the doubling of the Drammen Line, Slependen was rebuilt to the east, still on a curve, as an elevated station. This station was designed by Ina Backer. That station and the one to the east, Jong Station, were closed on 23 May 1993 and replaced by the current station, designed by Arne Henriksen. History The Drammen Line through Slependen opened as a narrow gauge railway on 7 Octo ... [...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 ...
