Klampenborgbanen

The line runs parallel to the Coast Line regional line from central Copenhagen until Klampenborg, and serves residential neighbourhoods in the eastern part of Gentofte Municipality as well as popular recreational destinations at Klampenborg such as the Dyrehavsbakken amusement park, the Jægersborg Dyrehave forest park or the Bellevue Beach.

Over the years it became difficult to run both the local trains to Klampenborg and the Elsinore trains on the same two tracks, and a dedicated local double track from Hellerup to Klampenborg was built in 1928.

As much of the population has moved out from the city center the Sunday traffic has become less important, but at the same time the line has gained a modest commuter patronage on weekdays.

Historically, service on the Klampenborg radial has often been reinforced in busy periods by ring line trains continuing northwards from Hellerup.

This practice has been abandoned (so far) with the 2007 timetable; instead the frequency of the main C service is doubled most of the day.
