A new report commissioned to review the two days of train chaos Sydney faced last month has found that the city’s tangled rail network and crew shortages were major contributing factors towards the system’s failure.

These major failures stopped trains on the tracks for 48 hours, left thousands of commuters stranded and saw other passengers turned away from stations due to overcrowding.

The report outlines that accelerating the recruitment of new drivers, working closely with unions to simplify rostering and changeovers, and improving the rail network’s support and IT system are all necessary measures to ensure that such an event doesn’t occur again soon.
