Safety Issue
Section 15, rule 5 of the network rules is only applicable for
'Two Position Lower Quadrant Signalling' areas and should not have
been used at the Separation Street overpass work site which had
'Three Position Signalling'. Further, section 15, rule 5 stipulates
additional but unspecified levels of site protection by the
'Ganger'. The level of protection needs to be qualified to ensure
the correct intent of the rule is observed. Neither of these
important qualifications is apparent when reading section 15, rule
5 of the network rules.
Safety Recommendation
The Australian Transport Safety Bureau recommends that the
Victorian Network Rules Consultative Committee take action to
address this safety issue.
