Uncontained battery failure involving Sydney Light Rail LRV053/054, Randwick Depot, NSW, on 3 April 2020

Investigation number:
Status: Active
Investigation in progress


The ATSB is investigating the uncontained failure of a roof-mounted battery on the Sydney Light Rail-operated light rail vehicle (LRV) 053/054 at Randwick Depot, NSW, on 3 April 2020. 

The light rail vehicles (LRV) 053 and 054 were coupled together and stabled in the Randwick light rail stabling yard. At approximately 0249, workers in the stabling yard heard a loud noise. On investigating the source of the noise, they located a roof-mounted battery box cover on the ground between two other vehicles. Further investigation identified that LRV 053 was missing a battery box cover.

Closed-circuit television cameras in the stabling yard showed the battery box cover being ejected from the train followed by a plume of smoke or vapour. There was substantial damage to the battery box on LRV 053. Additionally, there was minor damage to LRV005 and LRV058 as a result of the ejected cover landing between the two trains.

There were no reported injures.

An ATSB investigation is being undertaken by officers from the NSW Office of Transport Safety Investigations, under the provisions of the Transport Safety Investigation Act 2003. Investigators have commenced collecting evidence from involved parties.

Should any safety critical information be discovered at any time during the investigation, the ATSB will immediately notify operators and regulators so appropriate and timely safety action can be taken.

A final report will be published at the conclusion of the investigation.
