(ANSA-AFP) - ATHENS, MAR 3 - Greek police raided a train station Friday as part of their probe into the rail collision that killed at least 57 people, as the nation braced for new strikes and protests over the disaster. Some families were still desperate to locate loved ones who were on the train and some demonstrations have turned violent as public anger builds over the role government mismanagement played in Greece's worst-ever rail accident. A judicial source told AFP that files were among items seized by police on Friday during a raid on the Larissa train station in central Greece, where the fiery crash happened on Tuesday. The passenger train -- carrying many students returning from a holiday weekend -- ran for several kilometres on the same track as an incoming freight train, reportedly after the station master in Larissa failed to reroute one of the trains.
