On-screen gauge alert

The train control system software has been modified to provide for an acknowledgable on-screen alert in the event that a network controller attempts to set a route that includes the wrong gauge for the train that is to use it.

ATSB comment:

The ATSB is satisfied that this proposed action will adequately address the safety issue.

Proactive Action

Action number: RO-2013-009-NSA-060
Action organisation: Australian Rail Track Corporation
Date: 19 August 2014

ARTC will investigate with the Train Control System provider (Ansaldo) the option of removing the ‘route set’ functionality from the screen display where there is incompatibility between the route selected and the train gauge required.
