AN overnight train derailment in the state's North-West sent 10 wagons crashing from the tracks.
The incident occurred near Kimberley soon after 9.30 last night.
Nobody was injured in the derailment.
The incident comes less than a week after the release of an interim report into a Colebrook train derailment in November last year.
The investigation found that the train involved in last year's crash had been travelling twice as fast as the recommended speed, with the incident causing $4 million worth of damage.
However, in a statement released this morning, TasRail chief executive Damien White said speed was not a factor in last night's crash.
Mr White said the overnight derailment appeared to be track-related.
“This area of the network had not yet been upgraded but was scheduled for track re-sleepering in coming months,'' Mr White said.
''Our track engineers will carry out further inspections once the track is cleared and we will download and review all available train data over coming days.''
Mr White said he was confident a new, multi-million dollar train control system known as the Advanced Network Control System was operating at the time of the incident.
Work crews have today been called to clear and repair about 100 metres of track.
The Western line will remain closed for another 24 hours, with the company working with customers to minimise disruption.
An investigation to determine the cause of the derailment is underway.
The Australian Transport Safety Bureau and the Office of the National Rail Safety Regulator have been notified.
