Video shows moment of deadly Greece train crash as a station master reportedly admits "responsibility"

Video has emerged of the moment that a passenger train and cargo train collided in Greece late Tuesday night, killing at least 42 people in the country's deadliest-ever rail disaster. The video from a surveillance camera shows one of the trains approaching before a bright flash of light and a massive explosion.

More than 50 people were still hospitalized Thursday after the fiery crash, which has sparked a fierce debate over the state of the European nation's public transport network, as the cause of the disaster appeared to have been a case of human error.

Officials still haven't said exactly how the two trains ended up on a collision course on the same track, but the man in charge of a station in central Greece who was arrested Wednesday in connection with the crash has reportedly accepted "responsibility."
