More protests are expected in Greece four days on from the worst train crash in the country's history, which claimed the lives of 57 people. 

The funerals of the first victims took place on Friday, while some families and rescue workers are continuing to look for the belongings and remains of those who haven't yet been found.

As the clean-up and recovery operation continues at the crash site outside of the city of Larissa, inside the train station a vigil has been formed in memory of those caught up in the tragedy.

Hearts are heavy this weekend, with many people laying flowers, lighting a candle, and praying for the people, many of them students, who lost their lives.

University student, Akis, said: "It's really sad that young people have to die this way, instead of bringing them flowers at their engagement, their wedding or their graduation anniversary, we are bringing flowers at a vigil in their memory, it's really heartbreaking."

The Greek public are demanding answers as they try to find out the full facts about the cause of the crash.

"This is ridiculous, these were not only young people, but they also had their whole lives ahead of them, ready to blossom and now they are gone," said local resident Giannis. 

"I don't care if someone resigns or takes responsibility, I want actions, I want those responsible to pay, resigning doesn't mean anything to me. I haven't slept in a week, I avoid driving by the hospital, I can't."

North of Larissa, the funeral for the first victims of Greece's worst rail disaster was held on Friday after families received the remains of their loved ones following an identification process.

But some families continue to look for answers at hospitals and at the crash scene as many people remain missing.

The 59-year-old station manager based in Larissa has been arrested over the deadly collision.

The accused is facing felony charges of multiple counts of negligent manslaughter and other charges. 

It was at the Larissa station that the fatal mistake took place, but also the station where most of those young people called their loved ones, saying 'Don't wait up, there's a delay and we'll be late.'
