The ATSB is investigating a near miss between track workers and a moving passenger train on the down main line between Parramatta and Westmead, New South Wales, on 15 October 2019.

At approximately 2302, the Waratah train on run 133U departed Parramatta Station. The blocking facilities which had been placed on the absolute signals had been removed to route the train from the down main to the down suburban line via 727 points. The train effectively entered the ASB (Absolute Signal Block) worksite limits. The driver of run 133U was required to make an emergency brake application and stopped short of the civil work group. The civil work group consisted of four rail safety workers. The civil work group were on track to conduct welded track stability analysis measurements. A protection officer was facilitating access to the worksite with the Area Controller operating the Westmead Panel within Granville Signal Box. 

As part of the investigation, the ATSB will interview the civil work team, the signal controllers, the protection officer, the train crew and gather additional information such as workscope planning records, signal logs, and audio communication.

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

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