A group of pedestrians had a near miss when an out-of-control train smashed through heritage-listed level crossing gates in regional Victoria.
The Wendouree-bound train had a driver, conductor and two passengers on board when it failed to stop at Ballarat Station on the evening of May 30.
A preliminary Australian Transport Safety Bureau report released on Tuesday uncovered CCTV footage showing three people walking over the tracks 49 seconds before the crash.
The investigation found the train had experienced wheel-slide problems as it left Ballan Station after earlier starting its journey from Melbourne's Southern Cross.
Victoria's Transport Safety chief investigator Chris McKeown said the driver started braking slightly earlier than usual, owing to wet and windy conditions.
"An emergency brake application was applied 235m before the train's intended stop at Ballarat Station," Mr McKeown said.
"The train travelled through Ballarat Station at 100 km/h and passed a Departure signal at Stop as it headed towards the Lydiard Street North crossing."
It was still travelling at 93 km/h when it collided with the level crossing gates.
The crossing's road traffic lights only changed from green to flashing amber one second before impact but the gates were still across the track, investigators said.
The VLocity passenger train eventually came to a halt about 600m west of its intended stopping point.
One of the passengers, standing near an exit door on approach to Ballarat Station, suffered head, back, and leg injuries and was taken to hospital.
Investigators say the VLocity 3VL70 train's sanding system, which improves friction between the wheels and track to slow the locomotive, was experiencing "performance issues".
Its manufacturer, Bombardier, has undertaken fleet-wide testing of the devices and performed remedial action where required.
Investigations into the crash remain ongoing.
