It was a degraded on-board information system which showed incorrect speed and distance information to a train driver that has been labelled as the contributing factor to the train crash near Cloncurry in February last year.
The final report by the Australian Transport Safety Bureau into a two-train collision says the planned train crossing went wrong when one of the trains reported it had cleared the section of the track the other train was going past.
“The driver made an emergency brake application but was unable to avoid a collision. The collision caused minor damage to the lead locomotive of train 9T66 and the last wagon of train 9221, derailing its trailing bogie.”
There were no injuries.
The ATSB report says there were several factors that contributed to the crash between the freight trains besides the information system.
Pacific National has made changes following the accident.
