Transport Safety Bureau has released its final investigation report into the
derailment of a Metro Trains Melbourne (MTM) passenger train TD1067 near
Rushall Station, Melbourne, Victoria, on 6 February 2016.
The report highlights the importance of effective rail lubricator maintenance
to reduce the risk of derailment on small-radius curves.
At about 1650, the train was negotiating the most severe mainline curve on the metro network when the lead boogie of the second car derailed.
The ATSB investigation determined a decline in rail lubricator maintenance on the network resulted in excessive friction between the train’s wheel flanges and rail gauge-face on the curve causing the front right-hand wheel of the second car to climb across the rail and drop outside of the track.
To reduce the risk of future derailments on similar curves, MTM have installed new electronic lubricators across the network and have made significant changes to more effectively manage track conditions and faults.
