Two trains have collided head-on on a level crossing north-west of Copenhagen, leaving five people critically hurt and 13 others with less serious injuries, according to medical officials. The incident occurred early on Thursday on a line connecting the towns of Hillerød and Kagerup in North Zealand, with a total of 37 people reportedly on board the trains. Tim Ole Simonsen from the Greater Copenhagen fire department confirmed that all injured individuals had been evacuated to local hospitals. Local officials, including mayor Trine Egetved, expressed shock over the accident, emphasizing the need for thorough investigations to prevent future incidents. The Danish Accident Investigation Board arrived at the scene and is looking at a range of factors, including possible failures in the signaling system or human error. Rail accidents are rare in Denmark, making this collision particularly concerning.
