No timetable for Queensland Rail timetable restoration

It comes as it was revealed an inquiry into the state's troubled New Generation Rollingstock trains will not hold any public hearings.

LNP transport spokesman Steve Minnikin said it had been 18 months since major problems on the network began.

"I ask what date will Queensland Rail have finally fixed the trains?" he asked.

Facing estimates hearings on Friday, Mr Easy said if the question referred to the restoration of the timetable, "we are very focused and committed to restoring our services".

"It's important that the timetable and restoring the timetable involves a number of different variables, a number of different inputs, and that is a complex consideration," he said.

"When we're in a position to increase the services, we'll do so."

Following rolling cancellations beginning in October 2016 after the opening of the Redcliffe Peninsula Line which highlighted unsustainable levels of overtime and insufficient train drivers, Queensland Rail introduced a timetable with reduced services.

Queensland Rail spent $15.37 million on Deloitte consultants in the past year, who helped work on forecasting models.

Mr Easy said Queensland Rail was committed to implementing all of the recommendations from the Strachan inquiry, with 18 implemented so far.

"Over 95 per cent of our services are running on time and we've also provided over 99.7 per cent of our services under our current timetable," he said.

Mr Easy said the time taken to train drivers had reduced from about 18 months to 13 months.

Meanwhile, the terms of reference for an inquiry into the procurement of Queensland's new train fleet, which been plagued with issues including disability access, have been announced, with LNP and Labor governments to face scrutiny.

The inquiry, headed by retired District Court judge Michael Forde, will examine the "circumstances leading up to and associated with the procurement through a public-private partnership of New Generation Rollingstock trains which fail to comply with the disability legislation and functional requirements".

The inquiry will look into project milestones, technical specifications, project sponsor arrangements, the design approval process, engagement with the disability sector and decisions made by respective governments, statutory authorities and departments.

The commission may receive any relevant documents and conduct interviews but "may not conduct hearings".

Earlier this week, it was revealed the inquiry would be able to access cabinet documents.

The inquiry is due to report by December 3.

Transport and Main Roads director-general Neil Scales told estimates hearings he still believed the NGR was the right trains to order.

Both sides of politics have thrown blame on the other for the problems with the $4.4 billion NGR.

LNP deputy leader Tim Mander said the inquiry was a farce and the opposition was not consulted about the terms of reference.

"The LNP acted in good faith by agreeing to cooperate with an inquiry and suggested the independent Auditor General was the best office to review the entire process from start to finish and determine whether taxpayers get value for money," he said.

"[The] terms of reference have been manipulated to be so narrow that it won't look at all the issues in relation to the NGR including all design changes the Palaszczuk government have made since taking office in 2015."

Transport Minister Mark Bailey said members of the community would be able to make submissions to the inquiry, which would be made public unless confidentiality was required, with that decision to be made by Mr Forde.

"I welcome [the inquiry] and I look forward to the work [Mr Forde] he's going to be doing in the second half of the year," he said.

"Some people will be happy for them to be [public], and that's all good, some people may not."

The first of the 75-train NGR fleet was due to be operational in mid-2016.

An answer to a question on notice reveals there are 19 NGR trains in passenger service, with all the trains expected to be accepted by the 2019/20 year.

Mr Bailey is facing estimates hearings on Friday morning, with Housing Minister Mick de Brenni up after lunch.
