The lines used by the Copenhagen S-Train suburban rail system in Denmark are six radial, and two connecting rail lines built during the late 19th and early 20th centuries as commuter transport to and from the residential areas around the city centre.
The lines are, anticlockwise from north to south:
The two connecting lines are:
Five suburban radials routes - A, B, Bx, C, E, H - become a cross city route at Valby and Dybbølsbro, going through the Boulevard Line, branching out after Svanemøllen and Hellerup with the exception of, with the F line running semicircularly around the central part of Copenhagen, linking Hellerup with Ny Ellebjerg. It is possible to make an approximately 20 km circular (or oval rather) lap inside the city centre and its innerboroughs, by changing line at Ryparken (or at Hellerup), in the north, and a second change at Ny Ellebjerg in the south. One such lap includes stops at 20 stations.
The radial sections are connected to the central section with three from the south and west (Køge Bugt line, Høje Taastrup line and Frederikssundsbanen), as well as three from north and northwest (Hareskovbanen, Nordbanen and Klampenborgbanen). The system is designed so that a train from a given southern section can continue along any of the three northern and vice versa. In addition, the ring line is connected to the Nordbanen and Klampenborgbanen in Hellerup, but it is normally only used in connection with the Klampenborgbanen.
The December 2014 timetable has seven lines, each with a letter designation. Most run from about 0500 to about 0100 each day, with a train every 10 minutes in daylight hours and one every 20 minutes in the early morning and evening/night. The 10-minute interval begins later and ends earlier on weekends. Exceptions are service F, which runs once every 5 minutes (every 10 minutes on weekends); H, every 20 minutes in daytime to Østerport; and Bx, as an extra line on the Vestbanen and Hareskovbanen in the morning and afternoon(rush hours).
E, H and Bx skipped certain stops to provide faster travel time, but no trains skip stops inside the ring line.
As of January 2019, the line layout was changed on the northern branches as follows:
As of December 2020, the line layout was changed again on the northern branches as follows:
On weekdays all stations are served at least every 10 minutes until the evening. There are six main lines and one peak hour support line. Since all lines, with exception of one, use the same path through the city core, train departures occur every second minute there, at the general limit of metro lines. On most suburban lines, trains depart every five minutes. On Sundays these time intervals are doubled.
The network is slightly different on weekdays, weekends and nights.

 | All stops to Ny Ellebjerg | Ringbanen | All day | Ringbanen | All stops to Hellerup |
 | All stops to Ballerup | Frederikssundbanen | Daytime | - | Terminates at Østerport |
Before 2007, each line would run on a strict 20-minute schedule. In periods where more than three trains an hour were needed, the extra trains had separate service designations; for example service B+ ran on the same route as B, but only in the daytime and with its departure times offset 10 minutes from B.
Earlier timetables also had express services that skipped stops inside the ring line. [1]
In the weekends, only lines A, B, C and F run, operating six times an hour between 1000 and 1800 and every 20 minutes outside this timespan. The weekend services are:
| Name | Southern end | Northern end | ||
|---|---|---|---|---|
| | All stops to Køge | Køgebugtbanen | Nordbanen | All stops to Hillerød |
| | All stops to Høje Taastrup | Vestbanen | Hareskovbanen | All stops to Farum |
| | All stops to Frederikssund | Frederikssundbanen | Klampenborgbanen | All stops to Klampenborg |
| | All stops to Ny Ellebjerg | Ringbanen | Ringbanen | All stops to Hellerup |
Starting November 2009, the network has had distinct night services that depart twice every hour on Friday and Saturday night. The night services are:
| Name | Southern end | Runs when | Northern end | ||
|---|---|---|---|---|---|
| | All stops to Køge | Køgebugtbanen | Twice every hour | Nordbanen | All stops to Hillerød |
| | All stops to Høje Taastrup | Vestbanen | Twice every hour | Hareskovbanen | All stops to Farum |
| | All stops to Frederikssund | Frederikssundbanen | Twice every hour | - | Terminates at Copenhagen Central Station |
| | All stops to Ny Ellebjerg | Ringbanen | Twice every hour | Klampenborgbanen | All stops to Klampenborg |
There is one service for each of the radials at night, stopping at every station.
The Copenhagen Metro is a 24/7 rapid transit system in Copenhagen, Denmark, serving the municipalities of Copenhagen, Frederiksberg, and Tårnby.
The Copenhagen S-train, the S-train of Copenhagen, Denmark is a key part of public transport in the city. It is a hybrid urban-suburban rail serving most of the Copenhagen urban area, and is analogous to S-Bahn systems of Berlin, Vienna and Hamburg. The trains connect the Copenhagen inner city with Hillerød, Klampenborg, Frederikssund, Farum, Høje-Taastrup and Køge. There are 170 km of double track with 86 S-train stations, of which eight are in neighbouring towns outside greater Copenhagen.
Kystbanen is a regional railway line between Helsingør (Elsinore) and Copenhagen in Denmark. It was opened in 1897, and it is today the busiest railway line in Denmark. Kystbanen, along with an extensive network of railways in Scania, are run by DSB Øresund, part of DSB.

Transport in Copenhagen and the surrounding area relies on a well established infrastructure making it a hub in Northern Europe thanks to its road and rail networks as well as its international airport. Thanks to its many cycle tracks, Copenhagen is considered to be one of the world's most bicycle-friendly cities. The metro and S-train systems are key features of the city's well-developed public transport facilities. Since July 2000, the Øresund Bridge has served as a road and rail link to Malmö in Sweden. The city is also served by ferry connections to Oslo in Norway while its award-winning harbour is an ever more popular port of call for cruise ships.
