Queensland Rail was warned 10 months ago about the driver shortages that have played havoc with the train network but Transport Minister Stirling Hinchliffe says he was never told.

After a week of angrily blaming the rail operator for not letting his office know about impending problems, the minister said he was "deeply concerned" the external report had not been provided to him earlier.

"To be clear, I was only provided with a draft version of this report this evening at 9.20pm," he said, in a statement issued just before 11pm.

"The draft report clearly shows Queensland Rail personnel were aware from as early as January 2016 that there were significant risks attached to multiple projects as a consequence of a shortage of train driver resources."
