(ANSA) - BELGRADE, FEB 27 - The improper handling of the accident site at Tempe in central Greece, where two trains collided head-on on the night of February 28, 2023, resulted in the loss of vital information, experts from the National Aviation and Railway Accident Investigation Organisation (EODASAAM) said at the unveiling of its much-anticipated report on the deadly disaster on Thursday, according to the daily Kathimerini. "What happened - with the evidence being destroyed in three days - must never happen again," EODASAAM's lead investigator, Kostas Kapetanidis, said at a press conference presenting the report's findings, which paint a bleak picture of systematic failings, human error, poor oversight, chaotic procedures, a lack of coordination, and an almost complete lack of foresight," the daily reported. On the cause of the collision, the report states that the sequence of events that led to an undertrained stationmaster at the understaffed Larissa station accidentally routing passenger train IC-62 onto the same track as freight train 63503 on the same track when they were travelling in opposite directions on the night of February 28, 2023, "was highly affected by a general lack of strict application of the prescribed structured communication methodology." Furthermore, "with the existing evidence [it] is impossible to determine what exactly caused it, but simulations and expert reports indicate the possible presence of a hitherto unknown fuel," the report says, according to Kathimerini.
