Heraldo de Madrid - Head-on train crash kills dozens in Greece

Several carriages were almost completely destroyed in the collision between a passenger train and a freight train just before midnight on Tuesday, with at least one car appearing to catch fire and trap passengers inside.

"I've never seen anything like this in my entire life," said one rescue worker, emerging from the wreckage. "It's tragic. Five hours later, we are finding bodies."

Several cars had overturned or caught fire when they came off the tracks in the impact, leaving a tangled mess of metal and shattered glass.

The passenger train, carrying 350 people, had been travelling from the capital Athens to the northern city of Thessaloniki.

Health Minister Thanos Plevris said most passengers were "young people", with the train carrying many students returning to Thessaloniki after a long holiday weekend.

"It was a nightmare... I'm still shaking," 22-year-old passenger Angelos told AFP.

"Fortunately we were in the penultimate car and we got out alive. There was a fire in the first cars and complete panic."

"The collision was like a huge earthquake."

"I was stained with blood from other people who were injured near me," a passenger named Lazos told the newspaper Protothema.

Some 150 firefighters and 40 ambulances were mobilised for the response, according to Greek emergency services.

"The operation to free trapped people is under way and is taking place in difficult conditions, due to the seriousness of the collision between the two trains," spokesman Vassilis Vathrakogiannis told reporters.

He later said that 36 people have been found dead, while 66 injured were in hospital, including six people in intensive care.

Some 194 people have been rescued so far.

- 'Stained with blood' -

As morning broke Wednesday, two large cranes on the site were starting to clear parts of the wreckage as rescuers worked to free any passengers potentially still stuck in the damaged wagons.

One of the smashed carriages was lifted from a field next to the train tracks where it had landed after derailing, surrounded by scattered debris.

It is not yet known why the two trains collided in what local media is calling the worst "train accident that Greece has ever known".

"My thoughts are with the people in Greece this morning," tweeted the head of the European Council, Charles Michel.

"Shocked by the news and images of the collision of the two trains," he added.

The regional governor Kostas Agorastos told the Skai TV channel the death toll was likely to be "very high" and warned that the first two carriages on the passenger train "no longer exist at all".

- 'Windows exploded' -

On the local media site Onlarissa, a young woman said that the train "was stopped for a few minutes when we heard a deafening noise".

Another passenger told Skai television that "the windows suddenly exploded. People were screaming and were afraid".

"Fortunately, we were able to open the doors and escape fairly quickly. In other wagons, they did not manage to get out, and one wagon even caught fire," he added.

He said the accident was "unimaginable" and "would have been avoided if the safety systems were working".

An emergency government meeting was organised after the crash and military hospitals in Thessaloniki and Athens have been put "on alert" in case they are needed.

A three-day period of mourning has been declared.
