Kystbanen

Kystbanen ("The Coast Line") is a regional railway line between Helsingør (Elsinore) and Copenhagen in Denmark. It was opened in 1897, and is one of the busiest railway lines in Denmark. Kystbanen is operated by Danish State Railways (DSB).

Its original terminus was Østerport Station, but when the station was connected with Copenhagen Central Station in 1917, the terminus moved there. When the Øresund Bridge opened in 2000, service extended to Malmö in Sweden, though the section between Copenhagen and Malmö is a separate railway, the Øresund Line.

The railway services some well-known sights and locations such as Louisiana Museum of Modern Art in Humlebæk, Kronborg Castle in Elsinore, and Dyrehavsbakken in Klampenborg.

Since 2023 Kystbanen has no longer been served by Øresund trains to Sweden, and is instead integrated into DSB's regional train network, with trains continuing from Copenhagen to stations on Zealand.

Plans for a railway between Copenhagen and Helsingør (Elsinore) had been proposed since the childhood of railways. The North Line was built though Helsingør in 1864 and in 1863 the connection between Copenhagen and Klampenborg Station as a sort of daytrip and tourist route. In 1890 the Minister of the Interior, Hans Peter Ingerslev (Conservative People's Party), a proposition of a state railway between Klampenborg and Helsingør, but it went four years of discussion and negotiations before the surveyors could stop their work and the construction workers enter the field.

The Ministry of War wanted to have a railway to Vedbæk, as long as it wasn't built so close to the coast that it could be bombarded by a foreign naval fleet in Øresund, and as long as the railway could be removed quickly. The Forestry Department didn't have any objections against the railway as long as not even a single tree was cut down. A number of citizens also were active in the debate about the choice of route and placing of stations.

Because of rules decided by the Ministry of War, the railway had to go in a large curve out over the lakes to Nørrebro and onwards towards the Øresund Coast at Hellerup. Hellerup station was built in the 1860s because it was where the North Line and the Klampenborg Line split, and not because there was a need for a station at the place.

The section between Østerport and Hellerup was first taken into use with the opening of the Coast Line in 1897. Østerport was the initial terminus of the line, was originally called Kystbanestationen, Østerbro, København Ø and Østbanegaarden. Architect Heinrich Wenck, who drew many of the stations on the railway, was also responsible for the Eastern Station, that after decree from the Ministry of War was constructed as a temporary building. First 20 years later the line between Copenhagen Central Station and Østerport was taken into use, and the Coast Line got its present form on 1 December 1917.^{[page needed]}
