The ARTC issued a safety alert (number 52) on 27 September 2011 to advise all stakeholders of improvements to the rules and procedures. The changes were effective from 13 November 2011 and included significant changes to the TOA form and instructions for completing the new form.
The ‘Request’ section (TOA form ANRF-002B) clearly requires the location of the protection officer to be recorded. The section also provides for two work methods, a track vehicle journey and a fixed worksite. In each case, the form requires the start location and the end location to be clearly recorded. The ‘Validation’ section provides for two options if a train is known to be within the limits of the proposed TOA.
Optional step 11 states:
Train Number [number] is still within the limits of the TOA proceeding towards [location] and the Protection Officer has observed the identification number of the lead unit of the train [id number] which has passed beyond the starting point of the track vehicle journey or fixed worksite boundary, if following be prepared to stop. Note: The Network Control Officer must confirm the correct identification number of the lead unit of the train.
Optional step 12 states:
A track vehicle journey is to commence within the yard limits at [location]. Train number [number] is still within the limits of the TOA proceeding towards [location]. This train departed the starting point of the track vehicle movement, at [time, hours] follow and be prepared to stop.
The ATSB is satisfied that the action taken by the Australian Rail Track Corporation will adequately address this safety issue.
