 The National Rail Administration has developed a plan for possible expansion of the commuter rail . The main possibilities have been discussed : rebuilding the section from Sandnes to Egersund to double track , taking back into use the Ålgård Line , which branches off at Ganddal , and building a new branch from south of Gausel to Stavanger Airport , Sola . An alternative to several of the options is a light rail , which may or may not be built as a tram @-@ train , which would use parts of the existing double track between Stavanger and Sandnes .
