Safety actions Whether or not the ATSB identifies safety issues in the course of an investigation, relevant organisations may proactively initiate safety actions in order to reduce their safety risk. The ATSB has been advised of the following proactive safety actions in response to this occurrence. Additional safety action taken by TasRail TasRail has advised of the following proactive safety actions: Computer modelling by Worley Parsons to identify any additional criteria that could be used to interpret geometry measures to identify situations where a combination of defects could contribute to a heightened derailment risk. Update the TasRail Operational Risk Register V5 when outcome of modelling known - Hazard 2 - Train Derailment. Track Maintenance Standard INF-TS-211 has been updated (Version 3) on 04 April 2016 with respect to various operational and maintenance procedures, including: Removes the requirement to obtain track manager permission to travel over large faults and introduces geometry defect thresholds at which TSRs shall be applied enabling consistent management by the track inspector. Removes hazardous locations and introduces unstable twist defects which are locations that must be measured by inspectors during every patrol to mandate more rigorous monitoring of areas that rapidly deteriorate. Has been updated to include a revised repair advice sheet which now requires that measurements be taken for all reported geometry defects. Includes specific actions to be taken for each defect size Geismar digital geometry trolleys issued to all track inspectors to enable accurate sizing of defects. Track geometry vehicle now operated six weekly on busiest lines (South and Western). TasRail has committed to invest in its own, vehicle mounted, track geometry measuring equipment enabling more frequent and accurate track monitoring Update Infrastructure Derailment Form INF-FRM-019 to include the measurement of voiding following incident investigation. Fitting of Contact Side Bearers’ on the fleet of TQMF and IB wagons. ‘Constant Update standard RS-TS-006 to include side-bearer gaps clearances. Inspect TQMF wagons side-bearer gaps and friction wedges to ensure all are within specification. Update 'A' service sheet RS-FRM-242 to include inspection of side-bearer gap clearances measurements. Update wagon work instruction RS-Wl-531 to include correct service limits and measurement criteria.
