Ambitious plans for a new rail link between Aberdeen International airport, the new AECC and the city centre could be funded through a second City Deal, the council leader has said.
City council bosses unveiled their multi-million pound vision to create a track between the airport and the new Aberdeen Exhibition and Conference Centre at Bucksburn last September.
The plans, which would include new stations at the airport and the AECC, could cost as much as £70 million.
The proposals were to be funded by a devolution of air passenger duty to the local authority.
But the scheme suffered a setback after Holyrood ruled out the plan.
The council was then asked to submit a feasibility study to Transport Scotland and has been asked to submit a second more formal appraisal report.
Council leader Jenny Laing said the authority would look closely at the response and that the new line could be funded by a second £250m city deal.
She said: “This would be a huge strategic asset for the city and the wider region and is the sort of big thinking that we will need in the future.”
