The S-trains are a hybrid urban-suburban rail serving the Copenhagen urban area, except Amager.
The S-trains run between 05:00 in the morning and 00:30 at night. During daytime, Line F runs every 5 minutes, line A, B, C and E run every 10 minutes, and line H and Bx run every 20 minutes.
Friday and Saturday the trains run all night. However, line F runs every half hour during these hours.
Other types of trains not part of the S-train network include "Kystbanen" ("The Coastal Line") - a regional railway line between Copenhagen and Elsinore on the north coast of Zealand.
