The Skansen Bridge (Norwegian : Skansen jernbanebro) is a 52-meter span bascule railway bridge located at Skansen in Trondheim, Norway.
Norwegian is a North Germanic language spoken mainly in Norway, where it is the official language. Along with Swedish and Danish, Norwegian forms a dialect continuum of more or less mutually intelligible local and regional varieties, and some Norwegian and Swedish dialects, in particular, are very close. These Scandinavian languages, together with Faroese and Icelandic as well as some extinct languages, constitute the North Germanic languages. Faroese and Icelandic are hardly mutually intelligible with Norwegian in their spoken form because continental Scandinavian has diverged from them. While the two Germanic languages with the greatest numbers of speakers, English and German, have close similarities with Norwegian, neither is mutually intelligible with it. Norwegian is a descendant of Old Norse, the common language of the Germanic peoples living in Scandinavia during the Viking Era.
A bascule bridge is a moveable bridge with a counterweight that continuously balances a span, or "leaf", throughout its upward swing to provide clearance for boat traffic. It may be single- or double-leafed.
Trondheim is a city and municipality in Trøndelag county, Norway. It has a population of 193,501, and is the third-most populous municipality in Norway, although the fourth largest urban area. Trondheim lies on the south shore of Trondheim Fjord at the mouth of the River Nidelva. The city is dominated by the Norwegian University of Science and Technology (NTNU), the Foundation for Scientific and Industrial Research (SINTEF), St. Olavs University Hospital and other technology-oriented institutions.
The bridge was opened on March 22, 1918, allowing trains on the Dovre Line access to Trondheim Central Station while also being able to open to allow ships on the Trondheim Canal (Vestre kanalhavn) access to the Trondheimsfjord. It was built at the same time the Dovre Line was rebuilt from narrow gauge 1,067 mm (3 ft 6 in) to 1,435 mm (4 ft 8 1⁄2 in) standard gauge and the stretch between Marienborg and Trondheim Central Station was double tracked.
The Dovre Line is the name of a Norwegian railway line with three slightly different lines which all lead to the historic city of Trondheim.
Trondheim Central Station or Trondheim S is the main railway station serving the city of Trondheim, Norway. Located at Brattøra in the north part of the city centre, it is the terminus of the Dovre Line, running southwards, and the Nordland Line, which runs north. The railway is electrified south of the station but not north of it, so through trains must change locomotives at the station.
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying passengers or goods, or in support of specialized missions, such as defense, research and fishing. Historically, a "ship" was a sailing vessel with at least three square-rigged masts and a full bowsprit. Ships are generally distinguished from boats, based on size, shape, load capacity, and tradition.
Skansen Bridge was designed by structural engineer Joseph Strauss, who among other things also constructed the Golden Gate Bridge in San Francisco. The Strauss designed single-leaf iron truss railway bridge with overhead counterweight provides clearance for boat traffic. This type of bridge has a counterweight suspended in a parallelogram, as well as motors and gears to lift and lower the end of the bridge.
Joseph Baermann Strauss was an American structural engineer German descent, who revolutionized the design of bascule bridges. He was the chief engineer of the Golden Gate Bridge, a suspension bridge.
The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the one-mile-wide (1.6 km) strait connecting San Francisco Bay and the Pacific Ocean. The structure links the American city of San Francisco, California – the northern tip of the San Francisco Peninsula – to Marin County, carrying both U.S. Route 101 and California State Route 1 across the strait. The bridge is one of the most internationally recognized symbols of San Francisco, California, and the United States. It has been declared one of the Wonders of the Modern World by the American Society of Civil Engineers.
San Francisco, officially the City and County of San Francisco, is the cultural, commercial, and financial center of Northern California. San Francisco is the 13th-most populous city in the United States, and the fourth-most populous in California, with 884,363 residents as of 2017. It covers an area of about 46.89 square miles (121.4 km2), mostly at the north end of the San Francisco Peninsula in the San Francisco Bay Area, making it the second-most densely populated large US city, and the fifth-most densely populated U.S. county, behind only four of the five New York City boroughs. San Francisco is also part of the fifth-most populous primary statistical area in the United States, the San Jose–San Francisco–Oakland, CA Combined Statistical Area.
In 2006, Skansen Bridge received architectural conservation by the Norwegian Directorate for Cultural Heritage (Riksantikvaren) based upon Skansen Bridge being unique in Norway and only one of a few of its kind left in the world. The conservation includes the entire bridge including construction and technical equipment, the guard cabin and the transformer building. The conservation does not include the railway track, signal equipment or the overhead wires.
Architectural conservation describes the process through which the material, historical, and design integrity of any built heritage are prolonged through carefully planned interventions. The individual engaged in this pursuit is known as an architectural conservator-restorer. Decisions of when and how to engage in an intervention are critical to the ultimate conservation-restoration of cultural heritage. Ultimately, the decision is value based: a combination of artistic, contextual, and informational values is normally considered. In some cases, a decision to not intervene may be the most appropriate choice.
The Directorate for Cultural Heritage is a government agency responsible for the management of cultural heritage in Norway. Subordinate to the Norwegian Ministry of the Environment, it manages the Cultural Heritage Act of June 9, 1978. The directorate also has responsibilities under the Norwegian Planning and Building Law.
A transformer is a static electrical device that transfers electrical energy between two or more circuits. A varying current in one coil of the transformer produces a varying magnetic flux, which, in turn, induces a varying electromotive force across a second coil wound around the same core. Electrical energy can be transferred between the two coils, without a metallic connection between the two circuits. Faraday's law of induction discovered in 1831 described the induced voltage effect in any coil due to changing magnetic flux encircled by the coil.
The Norwegian railway system comprises 4,087 km of 1,435 mm track of which 2,622 km is electrified and 242 km double track. There are 696 tunnels and 2,760 bridges.
The Mystic River Bascule Bridge is a bascule bridge spanning the Mystic River in Mystic, Connecticut in the United States. It carries vehicle and foot traffic directly into the tourist district of town via 33 ft-wide (10 m) Main Street.
The Rauma Line is a 114.2 kilometres (71.0 mi) long railway between the town of Åndalsnes, and the village of Dombås, in Norway. Running down the Romsdalen valley, the line opened between 1921 and 1924 as a branch of the Dovre Line, which connects to the cities of Oslo and Trondheim. Originally intended as the first stage to connect Ålesund, and possibly also Molde and Kristiansund, no extensions have ever been realized. The unelectrified line is served four times daily with Norwegian State Railways' Class 93, although in the summer the service only operates from Åndalsnes to Bjorli as a tourist service. CargoLink operates a daily freight train.
The Røros Line is a 383-kilometer (238 mi) railway line which runs through the districts of Hedmarken, Østerdalen and Gauldalen in Hedmark and Sør-Trøndelag, Norway. The line branches off from the Dovre Line at Hamar Station and runs a more easterly route to Støren Station, where the two lines meet again. The Røros Line also intersects with the Solør Line at Elverum Station. The single track, standard gauge line lacks electrification and only has centralized traffic control south of Røros Station. The Norwegian State Railways (NSB) operate regional passenger trains. In addition the line is used by freight trains hauling lumber and wood chippings.
The Nordland Line is a 729-kilometer (453 mi) railway line between Trondheim and Bodø, Norway. It is the longest in Norway and lacks electrification. The route runs through the counties of Trøndelag and Nordland, carrying a combination of commuter, long-haul passenger and freight trains. From Trondheim Central Station to Steinkjer Station the line is most heavily used, with hourly services by the Trøndelag Commuter Rail. There are three branch lines—the Stavne–Leangen Line at Leangen Station, the Meråker Line at Hell Station and the Namsos Line at Grong Station.
The Finnish railway network consists of a total of 5,919 km of railways built with 1,524 mm Russian gauge track. Passenger trains are operated by the private state-owned VR. They serve all the major cities and many rural areas, though railway connections are available to fewer places than bus connections. Most passenger train services originate or terminate at Helsinki Central railway station, and a large proportion of the passenger rail network radiates out of Helsinki. VR also operates freight services. Maintenance and construction of the railway network itself is the responsibility of the Finnish Rail Administration, which is a part of the Finnish Transport Agency. The network is divided in six areal centres, that manage the use and maintenance of the routes in co-operation. Cargo yards and large stations may have their own signalling systems.
The Trondhjem–Støren Line was Trøndelag's first railway. It opened in 1864, ten years after the Trunk Line between Oslo and Eidsvoll opened. The 49 kilometer long railway line was narrow gauged and went between Trondheim and the Støren village in Midtre Gauldal municipality in the county of Sør-Trøndelag, Norway. The railway had its station, Trondhjem Kalvskinnet Station, in Prinsens gate, crossed the Nidelva river on a newly constructed railroad bridge to Elgeseter, the Elgeseter Bridge.
The Old Voss Line is a heritage railway between Garnes and Midttun near Bergen, Norway.
The Thamshavn Line was Norway's first electric railway, running from 1908 to 1974. Today it is operated as a heritage railway and is the world's oldest railway running on its original alternating current electrification scheme, using 6.6 kV 25 Hz AC. It was built to transport pyrites from the mines at Løkken Verk to the port at Thamshavn, as well as passengers. There were six stations: Thamshavn, Orkanger, Bårdshaug, Fannrem, Solbusøy and Svorkmo. The tracks were extended to Løkken Verk in 1910.
The Stavne–Leangen Line is a 5.8-kilometer (3.6 mi) railway line between Stavne and Leangen in Trondheim, Norway. The line provides an alternative connection between the Dovre Line and Nordland Line, allowing trains to bypass Trondheim Central Station. The line includes the Stavne Bridge over the river of Nidelva, Lerkendal Station and the 2.7-kilometer (1.7 mi) long Tyholt Tunnel. Construction of the line started during the Second World War by the Wehrmacht, the German military occupying Norway, in an attempt to make the railway in Trondheim resistant to sabotage. Because of the long construction time of the tunnel, tracks were laid in the city streets, but neither route was completed before the end of the war. Construction was placed on hold and the Stavne–Leangen Line did not open until 2 June 1957. At first it was primarily used by freight trains, but since 1988, passenger services have been provided.
The Trondheim Tramway in Trondheim, Norway, is the world's most northerly tramway system, following the closure and dismantling of the Arkhangelsk tramways in Russia. It consists of one 8.8-km-long line, the Gråkallen Line, running from St. Olav's Gate in the city centre through Byåsen to Lian Station in Bymarka.
The Nidareid train disaster was a train collision on 18 September 1921 on the Trondhjem–Støren Line railway line, between the stations of Marienborg and Skansen in Trondheim, Norway. The accident occurred the day after the inauguration of the new line to Trondheim, Dovre Line, and one of the trains involved was the inaugural train returning from the celebrations in Trondheim. Six people were killed in the crash, the first serious passenger train accident in Norway.
Hamar Station is a railway station of the Dovre Line and the Røros Line located in downtown Hamar, Norway. Located 126.26 kilometers (78.45 mi) from Oslo Central Station, it is served by long-distance and regional trains on the Dovre Line, as the terminus for regional trains on the Røros Line, all operated by the Norwegian State Railways (NSB). A side platform and an island platform are in regular use. The station handled 1,062,300 passengers in 2008.
Skansen is a railway station located at Ila in Trondheim, Norway. It is on the Dovre Line (Dovrebanen), 1.20 kilometers from Trondheim Central Station. Service to the station is provided though the Trøndelag Commuter Rail operated by Norwegian State Railways and regional trains to Røros Station. It was opened in 1893. The station is located in a residential area. It is the only railway station in Trondheim to have connections with the Trondheim Tramway. It is also served by city buses.
Eighth Street Bridge is a road bridge over the Passaic River in northeastern New Jersey, United States. Opened in 1915 as a bascule bridge, the bridge was fixed in place in 1977.
Gulfoss Tunnel is a 701-meter (2,300 ft) railway tunnel situated at in the municipality of Melhus in Trøndelag county, Norway. The tunnel runs beneath the village of Hovin, alongside the river Gaula past the Gulfossen waterfall. The tunnel carries a single, electrified track of the Dovrebanen railway line. The Trondhjem–Støren Line, which opened in 1864, crossed the river Gaula on a bridge to the opposite side of the river at the current site of the tunnel. This section of track was a challenge due to regular flooding. With the 1908 decision to build the Dovrebanen Line and gauge conversion, the Gulfossen section became one of two parts of the line to be reworked. Gulfoss Tunnel opened on 6 July 1918.

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
