Labor MP for Newcastle Tim Crakanthorp has accused the New South Wales Government of arrogance and wasting taxpayer's money by now seeking Parliament's approval to shut the city's rail line.

The Transport Minister Andrew Constance will give notice today of a bill to close the line.

A decision is pending in the Court of Appeal in a case between the Government and Save Our Rail after a hearing in July.

Mr Crakanthorp said the whole court case appears to have been a giant waste of money.

"This government is very arrogant and they have wasted huge amounts of taxpayer's money," he said.

"They should have got an act of Parliament in the first place and now taxpayers will have to foot the bill of a very expensive legal costs for a court cast that the government won't even wait for the result of."

Mr Crakanthorp said the Government is ignoring the community's wishes.

"They've put a lot of money into a court case that they are not even going to honour," he said.

"The court's decision it would appear, they're tired of this so they are just ramming it through.

"The people of Newcastle have signed petitions, gone on the streets, rallied , voted against this decision and the Government refuses to acknowledge Novocastrians opinions and what they want for their own city."

Transport Minister Andrew Constance said it is time for the city to revitalise and this project is the number one priority.

"It's time to put Labor's do-nothing legacy behind us and get this done," he said.

"I urge Labor to support the bill and support the revitalisation of Newcastle.

"The city has waited long enough.

"We always said we wanted to deliver the rejuvenation of the State's second city but we can't dither around anymore.

"Inaction now will prevent this once in a generation revitalisation proceeding quickly."

Mr Constance said they are introducing the legislation so they can get on with the project.

"We understand a decision from the Supreme Court is pending, but the longer this runs the more expensive it's likely to be, and the project is likely to be delayed," he said.

"We're kicking on and getting things done, just as promised.

"We could take the easy road and let this fall by the wayside, but we want regeneration of a great city underway."
