The man in charge of rostering for Queensland Rail has resigned amid an ongoing crisis at the rail operator that most recently resulted in hundreds of services being cancelled on Christmas day.
QR's chief operating officer, Kevin Wright, resigned from the role on Wednesday evening after emergency meetings were held to ensure services would be in place for the traditionally busy New Year's Eve.
AAP understands as a result of the meetings, Mr Wright was asked to tender his resignation.
Queensland Rail acting chief executive Jim Benstead sent a memo to all QR staff on Wednesday night informing them of the decision.
"As many of you know, Kevin has a long-standing career at Queensland Rail with more than 16 years of service culminating as head of our operations function," Mr Benstead wrote.
"I know many of you have met Kevin and have personally worked with him in some role or form."
QR executive Marty Ryan will take over Mr Wright's role from January 3, while the rail operator looks for a permanent replacement.
Mr Wright is the fourth executive to have paid a price for the crisis.
Former chief executive Helen Gluer and board chairman Michael Klug had resigned while the head of train service delivery was stood down since the initial staffing crisis in late September.
A lack of qualified drivers was sparked by the opening of the Redcliffe Peninsula rail line, leading to increasing pressure on the rosters, culminating in a series of service cancellations, most recently on Christmas Day when a third of the state's southeast services were cancelled.
At the height of the crisis in October, Mr Wright reportedly received a $77,000 performance bonus.
The department Mr Wright oversaw is the focus of the Strachan inquiry into the debacle and Transport Minister Stirling Hinchliffe has also commissioned a separate report into the crisis.
Mr Hinchliffe, who is facing continued opposition calls to resign over the rail debacle, has stopped short of committing to releasing that report publicly, saying he'll review it when it's handed to him.
"I'll then be making decisions about what information is appropriate to be made available out of the report," he said on Wednesday.
