Rescue workers are searching for survivors after a head-on collision between two trains in central Greece killed dozens of people and left scores injured, raising questions about the country’s poor track record of railway safety. Greece has a weak record of railway passenger safety compared with other countries in Europe, tallying the highest railway fatality rate per million train kilometers from 2018 to 2020 among 28 nations on the continent, according to a 2022 report from the European Union Agency for Railways. Clashes between protesters and police erupted on Wednesday outside Hellenic Train’s headquarters in Athens following calls to demonstrate against the fatal collision
