The 10-kilometre double track section, which covers seven stations between Nordhavn and Carlsberg / Sydhavn via Copenhagen Central Station, is now in operation with the new communications-based train control (CBTC) system.

This is the latest milestone in the major upgrade of Copenhagen’s S-train network.

Siemens Mobility was awarded a 252m euros (283.69m USD) contract install a CBTC system along the length of the S-train’s 170km network back in 2011, replacing signalling systems dating back to the 1970s.

The work was broken down into five stages, with upgrades completed to the Hillerød – Jægersborg section in 2016, and the Jægersborg – Klampenborg, and Svanemøllen – Ryparken section in 2019.

At the beginning of 2021, the Farum and ring lines were upgraded, with the completion of the central artery section bringing the total rollout of the system to 50 percent.

Work on the remaining sections is scheduled for completion this year.

Once the project is finished, the new CBTC system will enable the reduction of train headways from 120 seconds to 70 seconds within the inner-city.

Up to 84 trains an hour will be able to travel on the core network, which is equivalent to over 100 million passengers a year.
