The station master involved in Greece's worst-ever train disaster is due to appear in court on Saturday after at least 57 people died in Tuesday's collision between a passenger and freight train. The incident has led to mass protests across the country, with public anger mounting over government failure to manage the rail network.

The 59-year-old station master at Larissa, central Greece, has admitted responsibility for the accident, which saw the two trains run along the same track for several kilometres. The train was carrying many students returning from a holiday weekend, and at least nine young people studying at Thessaloniki's Aristotle University were among the dead, while another 26 were injured.

Prime Minister Kyriakos Mitsotakis, who is seeking re-election this spring, has described the disaster as a "tragic human error." The incident has prompted calls for greater investment in the country's rail infrastructure and a reassessment of safety protocols.
