The ARTC communication protocols did not provide the NCO adequate guidance with respect to standardised phraseology to ensure messages are clear and unambiguous.
The ATSB is satisfied that the actions taken by ARTC will adequately address this safety issue.
ARTC has issued a memo to all Train Control Centres with respect to communication protocols. The memo reiterated that communication protocols must be strictly adhered to. Additional random voice monitoring is now undertaken, that links to individual performance agreements.
