Seven people remain in Sydney hospitals after a train crash yesterday in Sydney's north-west, as authorities return to Richmond station to investigate the cause of the accident.
Sixteen people were taken to hospital after a train hit the safety bollards in Richmond, sending people tumbling in the carriages.
Four people are still in Westmead Hospital, along with three at Nepean Hospital.
A 77-year-old woman is being treated for possible collar bone and spinal injuries and a 22-year-old man has a suspected broken femur.
NSW Transport Minister Andrew Constance said there would be three independent investigations, run by different agencies, into the crash.
The passenger train was "slowing to stop at the station" when it crashed into a buffer at the end of the line, according to police.
Initial reports suggested the train derailed, but Sydney Trains CEO Howard Collins said it was still on its rails.
The Australian Transport Safety Bureau was helping the NSW Office of Transport Safety Investigations to piece together what happened.
Sydney Trains was also carrying out an internal inquiry.
Crews from Sydney Trains were in the process of moving the damaged train from Richmond station.
The train would be taken to nearby stabling yards for further tests, a spokesman said.
There were no delays to services on the T1 western line this morning.
