Two Trains Collide Head-On in Denmark, Leaving Four Critically Injured

Two passenger trains have collided head-on at a level crossing north-west of Copenhagen, Denmark, leaving four people critically injured and 11 others requiring hospital treatment, according to officials.

The crash occurred on a railway line connecting the towns of Hillerød and Kagerup in the North Zealand region of north-eastern Denmark.

Authorities say the cause of the collision is still unknown. Tim Ole Simonsen of the Greater Copenhagen fire department confirmed that all injured passengers were transported to hospital by ambulance or air rescue.

Frederiksborg Fire and Rescue reported being alerted to the incident at around 06:30 local time on Thursday.

Images broadcast by Danish media showed two yellow and grey trains with severe front-end damage positioned facing each other in a wooded area near the tracks.

Local mayor Trine Egetved described the incident as deeply shocking, adding that those with critical injuries were flown to the National Hospital in Copenhagen.

The railway line is heavily used by commuters, students, and workers in the Gribskov municipality.

While rail accidents are rare in Denmark, early expert suggestions indicate that one of the train drivers may have passed a stop signal, leading to the collision. The line is also believed not to be equipped with an automated safety system.

Mayor Egetved said the incident was unacceptable and stressed the need to ensure such a tragedy does not happen again.
