Greece resumed some train services and operations today, Wednesday, after a three-week halt following a catastrophic collision of two trains that forced authorities to stop all rail services across the country due to safety concerns. The train disaster sparked massive protests against the deficiencies in safety and security procedures in the dilapidated railway network. The government admitted to delays in installing modern safety systems in the rail transport network, conducting a judicial investigation but attributing the collision to human error. On the other hand, unions representing railway workers stated that the government has repeatedly ignored their demands for improved safety systems. The CEO of the railway authority said at a station in central Athens before the first resumed journey that railway services would gradually return over the next five weeks, noting that trains would operate at a slower pace with more staff present at stations to ensure safety.
