Rail safety issues and actions
Recommendation issued to: ARTC
|Date issued:||29 January 2008|
|Safety action status:|
|Background:||Why this Recommendation was developed|
The unrestricted speed of train 3AB6 on a relatively hot day provided sufficient dynamic force to cause the track, with its diminished stability, to misalign.
The current imposition of precautionary temperature-related speed restrictions recognises maximum temperature extremes but does not allow for a situation where daily temperature variations (minimum to maximum) are significant.
The Australian Transport Safety Bureau recommends that the Australian Rail Track Corporation takes further action to address this safety issue.
The ARTC in its submission did not accept that its approach to managing the impact of temperature on track stability was a safety issue.
