The railway line stretching from Oslo, in Norway, to Gothenburg, in Sweden, is currently one of the main bottlenecks along the TEN-T Scandinavian-Mediterranean Corridor. A feasibility study to double the track was recently published by the Norwegian Railways Directorate (Jernbanedirektoratet) and the Swedish Transport Administration (Trafikverket). Both entities agree that the best solution is to double parts of the railway rather than the whole line.
