Fewer bus services and a reduction in the number of full-time drivers are among cost cutting measures being introduced by Translink to offset cuts in their budget.
The company has named the routes that will be affected in Belfast and said there will be other changes “across the network”, Although frequency is being reduced, Translink said no routes will be cancelled.
The changes will be introduced on 1 September.
Mr Heading said he will be seeking a meeting with local Translink managers over the issue.
He said: “The cut will lead to reduced services in urban areas and more congestion, Translink’s strategy should be to get private cars off the road and increase public transport use by ensuring a service to meet current and future needs.
“Guarantees on rural services need to be in place before this strategy is implemented.
“I would like to know what consultation has taken place with passengers, the General Consumer Council and other public bodies and I will be asking for a meeting with local Translink Managers on this issue.”
