Hareskovbanen

The line was opened in 1906 as part of the private København-Slangerup Jernbane which went to Slangerup, about two thirds from Farum to Frederikssund.

This was quite a bit from the city center, but the station was supposed to be temporary until the exact routing of the various new railways near Copenhagen that were in planning around the turn of the century had been finalized.

However, the act was not followed by sufficient allocations of public money, and it would take until 1977 until S-trains could begin running on the line.

København L was abandoned and the terminus of the diesel trains moved to Svanemøllen in early 1976, and a year and a half later the conversion to S-trains were complete.

In the rush hours on Monday through Friday it is supplemented by the limited-stop service Bx.
