There existed an inconsistency between the track speed used for crossing assessment and permitted train speeds. The ALCAM process used a train speed equal to the track line speed, whereas V/Line systems for evaluating driver behaviour permitted an exceedence of line speed by up to 10 km/h for short distances.
The ATSB is satisfied that the action taken by VicTrack reduces the risk associated with this safety issue.
The Australian Transport Safety Bureau recommends that VicTrack takes action to address the inconsistency that exists between the crossing assessment that assumes a train travelling at line speed, and the sighting that would be required for a train travelling at the 10 km/h greater speed that is procedurally permitted by the rail operator.
VicTrack has elevated the issue to the National ALCAM committee for consideration.
The ALCAM Committee will issue advice to rail stakeholders supplying data into the ALCAM database that 'Maximum Train Speed' should be the highest allowed train speed at that location taking into account permanent speed restrictions or extreme grades.
VicTrack will consult with rail operators in Victoria regarding train overspeed policies.
