Hunter-based Nationals senator Ross Cadell is unsure whether a Coalition government would continue on the High Speed Rail project if elected.
Earlier this week, the project's business case was released to the public, disclosing the current plans to its development.
The High Speed Rail Authority has set the estimated cost of the Newcastle to Sydney line at nearly $90 billion, with the next two years to be spent on developing the final route plans.
It was also announced the federal government would be investing an additional $230 million into the project, putting the current expenditure at $660 million overall.
However, Senator Cadell is concerned the project may never come to fruition.
"We're spending hundreds of millions of dollars on feasibility studies for a project that will cost $100 billion in today's dollars," he said.
"We all know these budgets flow out and there is no allocation in the future.
"I don't think we'll see the start of this in two years, I don't think we'll see the finish of this in 50 years."
Ahead of next year's state election, Senator Cadell said if the vote goes to the Coalition, it's uncertain whether the project will be continued.
"I can't speak for everyone, but clearly I've got some concerns and I'll be voicing those concerns" he said.
"If our party room and shadow cabinet allay those concerns that will be supportive.
"But, I have not seen anything at the moment that shows a funding source where we can come up with $100 billion - that the government doesn't have - to fund it."
