Copenhagen S-train starts using CBTC signalling

Banedanmark has taken the digital train control system CBTC into use on Copenhagen’s S-train. More than half of the S-tog now runs with the new digital signalling system.

Last weekend, the first trip with CBTC, the latest generation of signaling systems for urban lines, was made in Denmark’s capital Copenhagen on the S-train (S-tog). Here, Banedanmark took the new system into use between Nordhavn in the north and resp. Carlsberg and Sydhavn in the south via Copenhagen Central Station, through which most S-train lines pass.

This means that the entire S-train network in inner Copenhagen has gone from running with old, analogue signals from the 1970s to new, digital signalling technology. “With the new system, we gather rails, trains and traffic centers in one system. As the new system is digital – and thus has fewer physical components – it becomes less vulnerable”, says Janus Steen Møller, director of Signal Systems in Banedanmark. This should result in more trains on time and a more stable train operation.

Nearing the goal

In the city centre, the S-tog trains run underground in two tunnel sections which are also served by regional trains. Everywhere else, the tracks are in the open, occasionally above or below street level. The roll-out of the digital signalling between Nordhavn in the north and Carlsberg and Sydhavn in the south is the penultimate in a row before the entire S-train can run with the new system.

At the end of 2022, Banedanmark can put an end to the very last rollout of the new signalling system on the S-line. Here, CBTC will be taken into use on the entire southern part of the S-line between Sydhavn and Køge as well as between Carlsberg and resp. Høje Taastrup and Frederikssund.
