The network rules and procedures require communications to be clear, brief and unambiguous. Network communications by various parties in Sydney Trains were not in accordance with the principles underpinning the network rules.
The ATSB is satisfied that this Audio Monitoring System will improve the safety critical communications as it is used to audit network communications for compliance and to identify improvement opportunities.
Sydney Trains established a Post Incident Assurance Group (PIAG) to respond to the incident. This group established key focus areas to promote the safety of workers and avoid future incidents.
To address this safety issue, a key focus area on ‘safety critical communications’ was established which was aimed at improving network communication processes in order to mitigate the risk of safety incidents occurring in the future.
Under a specific project (Safety Critical Communications Enterprise Wide Program) the aim was to improve the overall quality of network communications. To enable this, a separate system, the (Safety Critical Communications Audio Monitoring System) was implemented in September 2018 and provides an ability for safety critical communications to be captured, analysed and audited for compliance and improvement opportunities.
