 A branch to Sola has been considered to allow the trains to operate to Sola and the airport . The line would branch from the Sørland Line south of Gausel , and be built so trains from the branch could run both northwards and southwards . Proposed stations include the airport , Solakrossen , Forus West , Statoil 's head office and possibly the shopping center Kvadrat . This would give a travel time of 17 minutes from the airport to the city center , and 10 minutes from the airport to Sandnes . This route has , however , also been proposed as part of the light rail system . It would give about 2 @.@ 5 million annual passengers .
