Rail creep

Issue number: RO-2015-022-SI-01
Who it affects: Managers of rail networks
Issue owner: V/Line Pty Ltd
Operation affected: Rail: Infrastructure
Background: Investigation Report RO-2015-022
Date: 15 May 2017

Safety issue description

Asset management systems that were used to identify problematic levels of rail creep did not evaluate nor assess cumulative creep.

Proactive Action

Action organisation: V/Line Pty Ltd
Action number: RO-2015-022-NSA-037
Date: 15 May 2017
Action status: Closed

V/Line advised that it has updated the network standard for the inspection and assessment of lateral stability to include rules for the assessment of cumulative rail creep. It has also applied those rules in algorithms within the asset management system for the accurate assessment and generation of remediation work orders for cumulative creep.

Creep history not included in the new asset management system is being separately considered together with field validations.

Current issue status: Adequately addressed
Status justification:

The proactive safety action taken addresses the monitoring of future cumulative creep. The assessment of older records together with field validations should identify latent cumulative creep.
