Queensland Transport Minister Scott Emerson says it could take three months to investigate the cause of a train crash on Brisbane's bayside.
Large cranes were needed to remove the damaged carriages that ploughed into Cleveland Station on Thursday morning.
More than a dozen people suffered minor injuries when the passenger train ploughed through a toilet block at the station.
Mr Emerson says it is too early to speculate what caused the crash, but the station will not reopen until it is safe.
"There will be major disruptions for sometime," he said.
"We have put on buses from Cleveland to go to Ormiston - that does cause some delays for passengers but we are trying to get things done as quickly as we can.
"Clearly the rail safety regulator is holding an investigation along with the police.
"They will look at a whole variety of issues there ... and I am sure statements are being taken or are being taken and I am going to leave that to them."
