The Rodalies tunnel currently runs between lines 1 and 5 of the metro in the stretch of the Sagrera station. The positioning of the three tunnels has enabled the planning of a station which will permit intermodality between Rodalies and the metro.
It is expected that with the opening of the junction, the number of passengers will increase from the current 52,000 passengers/day (L1-L5) to over 130,000 passengers/day.
