Prevention minimises accidents

The Fehmarnbelt tunnel will be built to prevent and limit accidents

Prevention is a key word in the effort to minimise the risk of accidents and critical incidents in the Fehmarnbelt tunnel. Femern A/S has minimised the risk of serious accidents through the way in which the tunnel is designed and via its technology and equipment. The emergency services on the Danish and Swedish sides are collaborating on developing effective contingency arrangements for dealing with critical incidents. 

The tunnel comprises five tubes, which are all connected via emergency doors: two tubes for train traffic in each direction, two tubes for road traffic in each direction. There is also a corridor between the two road tubes running along the length of the tunnel. All tunnel tubes are connected by emergency doors at approx. 100 m intervals so that in critical situations, it is easy to get access between them in the event of possible evacuation. It is also equipped with advanced traffic monitoring equipment. 

No oncoming traffic

Driving is in one direction only in the tunnel so that motorists are not blinded by oncoming traffic. There are emergency lanes throughout the length of the tunnel in each of the double laned tubes for road traffic. In addition, crash barriers are designed so that the impact from a collision with a vehicle is minimised.  

As regards the railway, train traffic is also in one direction only in each tube. There are no switches in the tunnel or near the portals, which lead down into the tunnel. There are emergency escape ways on both sides of the tracks, which are designed to provide protection against consequential damage if a train is derailed. 


Did you know that...

... In partnership with the Danish and German police, the fire services and emergency services, Rail Net Denmark and Deutsche Bahn, Femern A/S has indentified and analysed around 500 types of possible accidents during the work to develop contingency plans for all conceivable situations in the tunnel.

Monitoring will ensure rapid intervention 

The tunnel will be monitored around the clock from a control centre outside the tunnel on the Danish side of the Fehmarnbelt, including via cameras in the road tunnel. Train traffic is also monitored from a control centre in Copenhagen. Both are staffed around the clock. 

Abnormal situations will be immediately registered so that the necessary measures can be implemented, e.g. if a vehicle drives overly slowly or a train comes to a halt. Temperature, air quality and the volume of traffic in the tunnel tubes will also be monitored. Road users and train personnel will be kept informed about conditions in the tunnel via radio and signage. Should an accident occur, the emergency services will immediately launch a well planned rescue and evacuation operation.
