The RER involves construction of a north-south tunnel beneath the centre of Buenos Aires connecting the Mitre and San Martin lines into Retiro with the Roca and Belgrano Sur lines, which link Buenos Aires and Constitución stations with the southern suburbs.
In the second stage of the project, an underground link will be constructed between Retiro and Once station, which will connect the Mitre and Sarmiento lines. In the longer-term, the government also proposes linking the metre-gauge Belgrano Sur and Belgrano Norte lines and incorporating them into the RER network.
When all phases are completed it is envisaged the RER reduce headway on the Buenos Aires suburban network from 10-15 minutes to just three minutes at peak times.
