Proactive Action

Date: 06 July 2016
Action status: Released

MTM advised the ATSB that ‘after consideration and testing of other options including flashing marker lights, MTM is developing a modification for inclusion in the Comeng Life Extension Program to increase the intensity of the marker lights to a level compliant with the standard for Railway Rolling Stock Lighting and Rolling Stock Visibility, AS/RISSB 7531.3:2007, including provision of a system to enable the automatic operation of the emergency battery back up in the event of loss of overhead power’.

ATSB response:

The ATSB accepts that the modification as proposed by MTM is a satisfactory risk mitigation measure. However, this measure is only applicable to the Comeng fleet. The Siemens trains in the fleet also do not meet the requirements of the AS/RISSB standard. Accordingly, the ATSB issues the following Safety Recommendation.
