STORY: The passenger train with 350 people on board collided with a cargo train near the city of Larissa in central Greece on February 28 in the country's deadliest rail disaster.

Rail workers, on strike since March 2, have extended their walkout until Friday. On Thursday, hundreds of university students marched through the streets of Athens.

The crash has stirred public outrage and protests against the conservative government and a political system which has repeatedly ignored calls by railway unions to install and maintain digital safety systems and hire more staff.
