Background: Investigation Report RO-2013-009

Safety issue description

The configuration of the dual-gauge points assembly led to a truncated broad-gauge rail in one of the turnout directions.

Proactive Action

Action organisation: Australian Rail Track Corporation
Action number: RO-2013-009-NSA-062
Date: 04 September 2014
Action status: Closed

Australian Rail Track Corporation is aware of the hazard posed by the cessation of the broad-gauge rail and will include consideration of it in future risk assessments as well as the option for additional controls (such as [1] the installation of indicators at dual-gauge turnouts to indicate track gauge configuration on both the straight and turnout routes; and, [2] the application of white, reflectorised branding to the top of the rail head near the end of the broad-gauge rail, and/or the welding of short lengths of thin steel to the head of the broad-gauge rail at such regular intervals as to create a ‘rumble-strip’ effect).

ATSB response:

 The Australian Transport Safety Bureau is satisfied that the action proposed by ARTC will adequately address the safety issue.
   
Current issue status: Adequately addressed
Status justification:

Addition of an on-screen warning prompt to NCO, changes made to the Caution Order issuing process, label instruction afixed to point machines.
