Banedanmark is the Danish state rail infrastructure manager, a government agency under the Ministry of Transport. It maintains and renews the state rail network, controls train traffic and allocates capacity to operators.
Banedanmark has around 2,800 employees. More than 3,000 trains a day run on its network, making 40,000 arrivals and departures at stations across Denmark.
The main line network includes 811.7 km of double-track and 927 km of single-track line. Banedanmark also manages the 171.4 km Copenhagen S-bane, while regional lines are managed by other infrastructure managers, including Lokaltog and Midtjyske Jernbaner.
Banedanmark’s predecessor was separated from DSB in 1997, leaving the state operator to run trains on infrastructure it does not manage. Every operator on the state network, including DSB and freight operators, depends on Banedanmark’s maintenance and traffic control for punctuality.
The Signalling Programme
Banedanmark’s Signalling Programme replaces the signalling on more than 2,600 km of main line and S-bane with digital systems. The main line receives ERTMS Level 2, combining ETCS train control with GSM-R radio, section by section until 2033.
Siemens completed a Communication-Based Train Control (CBTC) system on the entire S-bane network in September 2022. Main line sections are converted in stages. Bramming–Tønder and Esbjerg–Lunderskov switched to the new system in April 2025.
In May 2024 Banedanmark and Alstom agreed a new rollout plan for eastern Denmark after delays on several sections. The rollout there has to be coordinated with other large projects, including the Fehmarnbelt tunnel and the new line across Funen.
