TRACK DEFECTS are believed to have caused the derailment of an Amtrak train in central Florida last week, killing four passengers.
The northbound 40 car Amtrak Auto train was travelling from Sanford, Florida to Lorton, Virginia when it crashed in Sevilla, at 5pm local time. It was carrying 425 passengers and 200 cars.
Investigators from operator Amtrak, track owner CSX and the National Transportation Safety Board (NTSB) are still examining eight of the Amtrak vehicles, but are concentrating on possible causes of track misalignment.
Investigators are focusing on a heavy coal train that passed the spot minutes before the accident. They are also looking at drainage problems in the area.
It is believed that the driver saw that the track had spread, but was unable to stop the train.
NTSB investigator Keith Holloway said 'we are still getting information both at the scene and from the vehicles as well as taking witness statements.'
The line reopened on Sunday.
