COPENHAGEN — Two local trains collided head-on north of the Danish capital Copenhagen on Thursday, injuring 18 people, five of them critically, emergency services said.

Two yellow and grey trains stood at the site, both with visible damage to the front ​and facing each other on a tree-lined stretch of track, with rescue services describing “chaotic” scenes inside ​the carriages.

“The two trains collided head-on, causing large damage to them and sending broken ⁠glass flying everywhere,” fire and rescue service leader Christoffer Buhl Martekilde told reporters.

Early morning crash

A police spokesperson ​said it was too early to say what had caused the crash on the Gribskov train line linking ​the towns of Hillerod and Kagerup, adding there would be an extensive investigation.

A total of 37 people are believed to have been on board the two trains at the time of the crash, which occurred shortly before 6:30 a.m. (0430 GMT), the ​police said.

While health services attended to the injured, those who were not physically hurt were also offered ​assistance, said transport group Movia, parent company of rail operator Lokaltog.

“The serious train accident on the Gribskov Line deeply affects ‌us at ⁠Movia, and our thoughts go out to the injured, their relatives, and Lokaltog’s employees,” Movia board Chair Kenneth Gotterup said in a statement.

Emergency services scrambled 18 vehicles and 47 rescue workers to the crash site.

Swedish Prime Minister Ulf Kristersson said he had contacted acting Danish Prime Minister Mette Frederiksen to offer assistance.

Danish ​police said they had declined ​the Swedish offer to ⁠assist as local resources were sufficient.

“There are injuries among the passengers. Everyone is out of the trains, so no one is trapped… Large resources have been dispatched ​to the scene,” a spokesperson told Reuters earlier.

Denmark’s worst railway disaster this century ​occurred in ⁠2019, when a high-speed train hit an obstacle on a bridge during a storm, killing eight people and injuring many more in what police said was a difficult rescue operation.

While such accidents are rare in Denmark, one ⁠person was ​killed, and several others were injured in 2025 when a train hit ​a vehicle and derailed in the south of the country.
