Thirty-two new peak-hour trains are set to start on south-east Queensland's rail network this week, with an extra 14,000 commuter seats made available.

It comes after Queensland Rail slashed more than 100 services after the opening of the Redcliffe Peninsula Line in October 2016 and the continued struggle to recruit the 200 new drivers needed to fill the timetable gaps, identified by the Strachan inquiry.

Transport Minister Mark Bailey said earlier this year the new services would be added to the Shorncliffe, Cleveland, Redcliffe Peninsula, Ferny Grove, Springfield, Gold Coast and Airport lines.

"Queensland Rail is working hard to deliver an improved timetable, putting more trains back into service when customers need them most," he said.
