Safeworking Irregularity near Helensburgh Station, NSW on 21 August 2019

Investigation number:
RO-2019-016
Status: Active
Investigation in progress

Summary

The ATSB is investigating a safeworking irregularity of an absolute signal block applied on the rail line between Helensburgh and Waterfall that occurred at approximately 0410hrs on 21 August 2019.

At the same time, a passenger train (404A) was pathed on the down rail line towards Waterfall while the train crew of a freight train (4WM2) worked on their train under the presumption that the down rail line had blocking facilities applied.

The train driver of 4WM2 saw the passenger train approaching and gave red lights for the passenger train to stop. The passenger train driver stopped the train, then made enquiries to the North Panel Area Controller as to why he had been given red lights. The North Panel Area Controller advised there was no requested protection.

The driver of 4WM2 informed his co-driver that he had to stop a passenger train and that he needed to stop releasing hand brakes and move clear of the down rail line. The driver then contacted the Waterfall Signaller and informed him they were clear of the down rail line to enable the passenger service to continue to Waterfall.

At this time, the Waterfall Signaller clarified he had placed blocking facilities on the Up rail line only, while the train driver of 4WM2 said he needed blocking on both lines as they needed to walk along the down rail line while releasing hand brakes.

Preliminary review of the radio communications between the train driver of 4WM2 and the Waterfall Signaller indicates there was a lack of clear instructions as to why the blocks were required and there were no assurances repeated back by either party.

This investigation is being led by the Office of Transport Safety Investigator (OTSI). OTSI conducts rail investigations in NSW on behalf of the ATSB under the Transport Safety Investigation Act 2003.

As part of the investigation, OTSI is making inquiries into other information and communications that may have occurred at the time of the occurrence and into the events leading to the freight train being stopped at the location.

A final report will be released at the end of the investigation.

Should a critical safety issue be identified during the course of the investigation, the ATSB will immediately notify those affected and seek safety action to address the issue.
