At least 36 were killed when a passenger train and a cargo train collied in northern Greece, with the search for survivors continuing, media reports said Wednesday.
The death toll may rise as the passenger train was carrying 352 onboard, said the public broadcaster ERT.
It said the victims include nine railway employees and university students returning to school in the northern port city of Thessaloniki from Larissa and Athens.
Search and rescue teams are working to pull survivors from the wreckage, it noted, adding that at least two cranes are being used to remove passenger carriages.
Many ambulances and fire engines are also at the site and psychologists were sent to the Larissa General Hospital to provide support to the families of the victims and passengers.
Blood donation campaigns were initiated by the Greek Red Cross in many municipalities, including the capital city of Athens.
The 59-year-old station master responsible for overseeing railway traffic in the area has been arrested.
The manager initially denied he made a mistake but later changed his story.
"I made a mistake and sent the passenger train on the same line as the commercial one coming from Katerini (direction)," he said.
Transport and Infrastructure Minister Konstantinos Karamanlis announced his resignation in the aftermath of the deadly collision.
