Head-on train collision near Copenhagen injures 17, four critically

Two local trains collided head-on at a level crossing near Kagerup, north of Copenhagen, leaving at least 17 people injured and four in critical condition. The emergency alert came in at 6:30 a.m. Thursday at Isteroedvejen, on the Gribskovbanen line between Hillerød and Kagerup, about 40 kilometers north of the capital.

Police described the crash as a major incident, while the Greater Copenhagen Fire Department said its response was large. All passengers were evacuated and no one was trapped inside the trains, but the force of the collision was serious enough that some of the injured were flown to hospital. Region Hovedstaden said 17 patients were treated in total, including 12 people with minor injuries.

The scene put immediate focus on the safety systems protecting the route and the crossing itself. Two local trains should not end up striking each other head-on on a commuter line that serves communities north of Copenhagen, and the crash raises pressing questions about how traffic was controlled on the track section at Isteroedvejen and what barriers or signals, if any, failed to prevent the collision.

Gribskov Municipality Mayor Trine Egetved said the line is heavily used by local residents, employees and schoolchildren. That makes the crash more than a local disruption. It is a public safety event that cut into a line woven into daily life across Gribskov and North Zealand, where people depend on rail service to get to work, school and appointments.

The crash also reopened wider concerns about rail oversight in Denmark, a country with a strong reputation for transport safety. A train crash in 2019 killed eight people and injured 16, and in August 2025 an express train hit a farm truck at a crossing, killing one person and injuring 27. Together, the incidents have sharpened scrutiny of how crossings are protected and how quickly failures are identified before they turn into mass-casualty events.

For passengers on Thursday morning, the danger was immediate and personal. For the rail network, the question is larger: how two local trains could meet head-on on a modern commuter line, and whether the protections meant to keep them apart were absent, failed, or were not enough.
