This morning, a group of commuters at Stirling station on Australia's Transperth line worked together to lift a train and free a man whose leg was trapped between a car and the platform.
"He stood in the doorway and as he was sort of taking up his position there, one leg slipped outside the door, slipped outside the gap, and he was stuck," he said.
"We alerted the driver, made sure the train didn't move.
"Then our staff who were there at the time got the passengers, and there were lots of them, off the train, and organised them to sort of rock, tilt the train backwards away from the platform so they were able to get him out and rescue him."
Mr Hynes said the train was stationary when he slipped.
"He was walking so he was reasonably OK," [witness Nicolas Taylor] said.
"He seemed to be a bit sheepish, because right where he fell was the 'mind the gap' writing."
