A TRAM-train link between Glasgow Airport and the city centre will cost more than £90 million to introduce, according to experts.
Consultants reviewing transport options have concluded that the preferred option of running trams jointly on newly-built light rail lines and existing heavy rail infrastructure would be the second most expensive option, at an estimated £92.4m.
It compares to an estimated £207.4m to reinstate a heavy rail project, while a third option of running futuristic bubble cars was estimated at £71.7m.
The final report on the issue was jointly commissioned by Glasgow Airport, Transport Scotland, and Glasgow and Renfrewshire councils to find the best way of improving access to the airport, which can currently only be reached by road.
Transport Minister Keith Brown announced last month that tram-trains were the preferred option.
