Safety Issue
The 'Test & Commissioning Plan' was deficient in that it did
not adequately address the split of responsibilities between the
engineer (responsible for managing the wiring alteration process)
and the technician (for facilitating train safeworking and
implementing WNR's signalling policies and procedures). This
uncertainly may have led to some confusion regarding the ownership
of important train safeworking decisions.
Safety Recommendation
The Australian Transport Safety Bureau recommends that WestNet
Rail take action to address this safety issue.
