Security footage of an escalator crush that injured 13 people at a Perth train station indicates a group of people stopped at the bottom, which prevented others from stepping off.
The Public Transport Authority has obtained CCTV footage of the incident at the Esplanade station on Saturday and says early indications are that when people stopped at the bottom, several passengers fell over each another.
"The escalator was switched off by a passenger pressing the emergency stop switch within 30 seconds of the incident starting," a spokeswoman said.
She said there was a "reasonable sized" crowd of people who appeared to have come from an event at the nearby Convention and Exhibition Centre, but the crowd was no larger than a normal afternoon peak.
"It also appears some of the passengers may have been less experienced public transport users and this may have caused them to pause at the bottom of the escalator rather than move down the platform," she said.
A full safety check has been carried out on the escalator and no faults have been found, the spokeswoman said.
