"The disaster occurred after years of multiple warnings from the train drivers' official union, while the current government was passing legislation that would make drivers' ability to strike or take industrial action for safety concerns unlawful."
"Three weeks before the crash, the rail workers' union had raised concerns over problems with the administration of the rail network which could put the passengers in danger."
