Status: Active
Investigation in progress


On 29 June 2021, at Harefield, New South Wales, a speed restriction was not applied following welding repairs which allowed passenger train, ST24, to traverse a section of track at 115 km/h when a 40 km/h speed restriction should have been in place. There was no damage or injury as a result.

An investigation being led by the NSW Office of Transport Safety Investigations (OTSI) is currently underway. OTSI conducts rail investigations in NSW on behalf of the ATSB under the Transport Safety Investigation Act 2003. OTSI transport safety investigators have commenced collecting relevant evidence and statements from involved parties. 

A report will be published at the conclusion of the investigation. However, should any critical safety issues be identified at any stage during the course of the investigation, the ATSB will immediately notify relevant parties so appropriate safety action can be taken.
