The Advantages of the New Signals

The effects of the new signals are a reduced number of delays, higher speed on certain routes and an increase of the number of train in operation.

A uniform high level of safety and a reduced number of train delays are some of the benefits of the new signalling systems.

The Main Line
On the Main Line, the current signalling system will be replaced by the common European ERTMS level 2 system. The system is a modern IT based signalling system, where the signals are no longer along the rail tracks, but on the screen in the driver’s compartment.

With the complete replacement of all signalling systems, approximately 80 pct. of all delays due to signal failures will not occur in the future. The new technologies will also be based upon the common European ERTMS for the Main Line and the standard suburban rail system CBTC for the S-trains.
This means that it will be much easier to procure spare parts as well as maintaining the new systems in the future.

Furthermore, the ERTMS is an interoperable system and has jointly been developed through  European Commission initiatives in order to promote European train travel. The ERTMS enables trains to pass through countries without having to adapt to additional train protection systems, radio or other signalling system equipment specific to the particular country. This system will gradually replace the national train control systems.

The introduction of ERTMS on the Main Line will bring a number of advantages in comparison to the current systems:

  • A reduced number of train delays
  • Improvement of passenger information
  • Reduction of the equipment and material in the vicinity of the track
  • Uniform high level of safety nationwide
  • Potential increase in speed level and as a result, quicker travel time on certain routes
  • Potential increase in the number of trains in operation on certain routes
  • Reduction of operation and maintenance costs
  • Enabling the introduction of more direct train services to other European countries

S-train Network
On the S-train network, the current signalling system will be replaced by the CBTC system. This modern railway system is used in other major cities such as New York, London and Paris. 

Along with the expansion of the metro in Copenhagen, the new system will improve the quality of the public transport in the Greater Copenhagen area. It will also ensure a reduced number of train delays, uniform train control and a higher speed on several stretches.

The introduction of the new signalling system will also entail less physical material in the vicinity of the tracks. This will result in a reduction of maintenance costs and make it easier to install the new system, while the S-trains are in service.
