Besieged Transport Minister Stirling Hinchliffe has promised Queensland Rail's latest revised timetable will finally deliver reliable and consistent services for fed-up commuters.

The new scaled-back timetable will be rolled out Monday morning, two-and-a-half weeks after a driver and guard shortage triggered commuter chaos across the south-east's rail network.

More than 330 services have been slashed from the timetable that was introduced last month in conjunction with the beginning of the new Redcliffe Peninsula line.

Since the network was stretched to breaking point, due to a lack of staff and trainers, QR has seen its chief executive and chairman resign, plus a number of service cuts.
