The Barcelona orbital line (Catalan; Valencian: línia orbital) is a railway project forming part of both the Pla d'infraestructures de Catalunya (PITC),[1] a long-term development plan due for completion in 2026, and the Pla de transport de viatgers de Catalunya (PTVC),[2] a short-term plan due for completion in 2012. In following perimeter routes the orbital line and another railway project, the Eix Transversal Ferroviari de Catalunya,[3] are the first railway schemes to depart from the radial system developed so far in the Barcelona area.[4]
Also known as the Quart cinturó ferroviari,[5] the orbital line will connect Rodalies Barcelona services between Vilanova i la Geltrú and Mataró via a 119km (74miles) line passing through Granollers, Sabadell, Terrassa, Martorell and Vilafranca del Penedès, but avoiding the actual city of Barcelona. Some sections will make use of existing track belonging to Administrador de Infraestructuras Ferroviarias (Adif) and operated by Renfe Operadora, whilst 68 km of track - of which 46km (29miles) in tunnels - and 23 new stations will be constructed.
