"Why don't we look at it for State Rail and State Transit? We all know that the people that come in in peak hour should principally be those people that are going to work. They have the capacity to pay," he said.

"Whenever we go and talk about that, the first thing the politicians do is what I call 'Labor disease', which has now become general," Mr Moore-Wilton said at the event, hosted by the Tourism and Transport Forum.

"They say, 'Well we don't want the average punter to pay differentially, we don't want the pensioners to pay deferentially,' and it's left to the merchant bankers to pay. Well they're not the great bulk of the people.

"You've got to tell the people, if we are going to improve peak-hour congestion, those people that need to come for their work should be prepared to pay more. Those people that don't should be encouraged, and I use the word encouraged, through lower pricing."

Mr Broad has raised the idea of free train travel before 7am with the state government. It is unclear if Infrastructure NSW has also raised the idea of higher fares for peak-hour commuters.
