A long-awaited investigation into Greece’s deadliest train crash has blamed human error, outdated infrastructure and major systemic failures for the head-on collision that killed 57 people two years ago.

The 178-page report was released on the eve of a general strike and mass protests planned for the anniversary of the crash on February 28 2023, fuelled by public anger over the slow pace of a separate judicial inquiry.

The independent investigative committee found that a routing mistake by a station master sent a passenger train onto the same track as an oncoming freight train.

Investigators also highlighted poor training, staff shortages and a deteriorating railway system that lacked automated safety controls, noting a chronic lack of public investment during the 2010-18 financial crisis.

The findings were published by the Hellenic Air and Rail Safety Investigation Authority.
