The ARTC procedure ANPR-701 (Using a Track Occupancy Authority) was inconsistent in that it did not allow for a scenario that would otherwise be permitted, and intended, under rule ANWT-304 (Track Occupancy Authority).
ARTC advised of processes to address the issue
The ARTC has trained its employees in this particular scenario and will review the procedure to ensure that it is consistent with the training and the TOA Form.
The ATSB is satisfied that the Australian Rail Track Corporation has initiated action to address this safety issue.
