Frederikssundbanen

Frederikssundbanen is one of six radial S-train lines in Copenhagen; it connects the city center with a number of Northwestern suburbs and other townships until Frederikssund on the Western coast of the Nordsjælland peninsula.

The service pattern on the inner part of the line is the C service which stops at all stations until Ballerup. On the outer part the basic service is H, which runs partially non-stop until Ballerup. The H service is peculiar in that its frequency is not doubled during daylight hours, as all other basic S-train services are. Instead, in the period where C is doubled, half of its trains continue to Frederikssund, providing 6 trains per hour in total on the outer part of the line, too. This daylight-only extension is indicated as "" in the above table.
