On Wednesday, July 1, Dunbar station will transfer from Virgin Trains East Coast to ScotRail with the prospect of changes ahead.
A one-way system and extension to the car park is being looked at as well as integrated transport arrangements.
East Lothian councillor Michael Veitch, council spokesman for transport and roads, was hopeful a solution to car parking pressures could be reached after the transfer of the station.
He said: “Top of our list will be the car park.”
Complaints have been made by residents in surrounding streets because the station car park is usually full by 8.30am, and other station users are parking in nearby streets.
“Some time ago, East Lothian Council put together plans to open up Spott Road and have a loop system and create a transport hub at the station,” said Mr Veitch. “Extending the car park would be part of that.
“The plan is for the council to submit a funding application to the Scottish Stations Fund. We will try to secure funding for the Dunbar station but also for some other car parks to be extended.”
The station has 76 spaces, and up to 25 more spaces could be created.
A spokesman for ScotRail said: “There are currently no plans to withdraw the parking charge (£4 daily). However, our car parking strategy is subject to reviews and takes into account demand and prices.
“We constantly look at the potential for more parking spaces.”
