Double track in the context of "Liverpool and Manchester Railway"

The Hindenburgdamm or Hindenburg Dam is an 11 km (7 mile) long causeway joining the North Frisian island of Sylt to mainland Schleswig-Holstein. Its coordinates are 54°53′N 8°33′E / 54.883°N 8.550°E / 54.883; 8.550. It was opened on 1 June 1927 and is exclusively a railway corridor. The companies that built the Hindenburgdamm, a job that took four years, were Philipp Holzmann AG of Frankfurt, working from the mainland, and Peter Fix Söhne of Duisburg working from Sylt. A train trip along the causeway takes about 10 minutes, and the time between the auto terminals at Niebüll on the mainland and Westerland on Sylt is about 30 minutes. The Hindenburgdamm is part of the railway line known as the Marschbahn ("Marsh Railway"), which is double-tracked along much of the route, although there as yet exists a single-tracked stretch. On the causeway is a signal box. The rail line is not electrified making the use of diesel locomotives necessary. Trains coming from origins further south like Hamburg change from an electric locomotive to a diesel locomotive at Itzehoe.

Every day, more than 100 trains pass over the causeway, 50 of those ferrying cars (there is no road link to Sylt). Each year, the railway ferries more than 450,000 vehicles over the causeway.

Tawa railway station, originally called Tawa Flat, is on the North Island Main Trunk Railway (NIMT) and is part of the suburban rail network of Wellington, New Zealand. It is double tracked with an island platform, and is 13.75 kilometres (8.54 mi) from Wellington railway station, the southern terminus of the NIMT. The station serves the suburb of Tawa.

Hamar Station (Norwegian: Hamar stasjon) 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 trains are operated by SJ Norge, except the regional trains between Lillehammer and Oslo, which are operated by Vy. A side platform and an island platform are in regular use. The station handled 1,062,300 passengers in 2008.

The station opened on 23 June 1862 as the western terminus of the narrow-gauge Hamar–Grundset Line, today the Røros Line. The first station building, in Swiss chalet style, was designed by Georg Andreas Bull. Increased traffic caused the construction of a second station building, designed by Balthazar Conrad Lange. It opened in 1880 with the first part of the Dovre Line, which connected Hamar to Oslo. The current station building is designed by Paul Due in historicism. It received major renovations in the 1970s and ahead of the 1994 Winter Olympics. The Dovre Line past Hamar will be upgraded to double track, and in conjunction with this moving the station is being considered.

The Copenhagen S-train (Danish: S-tog), the S-train of Copenhagen, Denmark, is a key part of public transport in the city. It is a hybrid urban-suburban rail serving most of the Copenhagen urban area, and is analogous to the S-Bahn systems of Berlin, Vienna and Hamburg. The trains connect the Copenhagen inner city with Hillerød, Klampenborg, Frederikssund, Farum, Høje-Taastrup and Køge. There are 170 km (110 mi) of double track with 87 S-train stations, of which eight are in neighbouring towns outside greater Copenhagen.

The S-train is run by DSB S-tog A/S while Banedanmark owns the tracks and signals. Rail services are operated by "Fourth Generation" S-trains divided into 104 8-car train sets (Class SA) and 31 4-car train sets (Class SE).

The Walkway over the Hudson (also known as the Poughkeepsie Bridge, Poughkeepsie Railroad Bridge, Poughkeepsie–Highland Railroad Bridge, and High Bridge) is a steel cantilever bridge spanning the Hudson River between Poughkeepsie, New York, on the east bank and Highland, New York, on the west bank. Built as a double track railroad bridge, it was completed on January 1, 1889, and formed part of the Maybrook Line of the New York, New Haven and Hartford Railroad.

The bridge was removed from service on May 8, 1974 after damage from a tie fire. It was listed on the National Register of Historic Places in 1979, and its entry updated in 2008. The bridge was designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers in 2009.
