A "furious" Queensland premier has refused to rule out firing those responsible for a shortage of train drivers that thre Brisbane's rail network into chaos on Friday.
Annastacia Palaszczuk has demanded Queensland Rail explain why the government and public weren't notified of the driver shortage until the night before more than 100 services were cancelled.
The driver shortage is linked to the opening of the Redcliffe Peninsula Line in early October but Ms Palaszczuk said the first she or transport minister Stirling Hinchliffe knew of the shortage was Thursday night.
"I am absolutely furious... I want to know very clearly from the Queensland Rail board: how did this happen?" she told reporters in Proserpine.
"Surely someone in Queensland rail knew this was going to be a problem and failed to alert higher up the line."
The driver shortage is expected to affect Brisbane lines for several weeks and Queensland Rail is rushing to pull together a scaled-back timetable.
The government says 100 extra drivers should come online soon after completing their training.
Ms Palaszczuk indicated the jobs of senior Queensland Rail staff might be on the line over the debacle.
"I would not rule that out, because how did it get to this?"
But Deputy Opposition Leader Deb Frecklington said Mr Hinchliffe should take responsibility for the cancellations.
"This is an issue that didn't happen overnight, it's an issue the minister needs to stand up and take some responsibility for."
