Accident in southern Germany might be result of human error

As recovery efforts at the site of a deadly train crash continued, the cause of the head on collision with ten dead and more than 80 others injured remained unclear.

According to German authorities, the ongoing investigation is focusing on the so called ‘PZB 90 system’ – a mechanism which “is supposed to automatically ensure that train collisions don’t happen,” as the German Transport Minister put it hours after the crash on Tuesday.

According to a German rail representative, the system on that particular stretch of tracks was checked as recently as last week and was found to be in working order.
