Transport Minister Stirling Hinchliffe has failed to guarantee the head of Queensland Rail will keep her job following a driver shortage which resulted in major network delays.
The shortage resulted in more than 100 services being cancelled on Friday, creating commuter chaos during the morning and afternoon peaks.
Standing beside her at a Monday press conference, Mr Hinchliffe deflected direct questions as to whether QR chief executive Helen Gluer's job was safe.
The transport minister would only say the state government was concentrating on fixing the immediate issue.
"The absolute focus that I have is to deliver the reliability and services that Queensland commuters expect and rely upon," he said.
"I know the CEO is working 100 per cent focused on that; I am working 100 per cent focused on that; and then making sure we can deliver for the future beyond that."
Mr Hinchliffe has come under fire himself for attending the Gold Coast 600 Supercars event over the weekend instead of attending an emergency QR board meeting, although he did teleconference with them.
Deputy opposition leader Deb Frecklington has also called for him to be axed by Premier Annastacia Palaszczuk.
"This is a minister who has been in hiding since this issue arose, and he needs to explain to the people of Queensland where it all went wrong," Ms Frecklington said on Monday morning.
"So the question is, is Annastacia Palaszczuk strong enough to sack this incompetent transport minister?"
A temporary timetable has been put in place for the next two weeks as QR scrambles to overcome the shortage of drivers, largely caused by the opening of the new Redcliffe Peninsula line.
