The network comprises pre-existing suburban lines joined together in modern tunnels under the centre of Paris. The essential central part of the network was completed by a massive civil engineering effort between 1962 and 1977, and features some unusually spacious deep stations. As of 2005 the RER comprises five lines: A, B, C, D and E.

The Parisian RER is also notable in that certain lines are operated by the city transport authority (RATP) and others by the national rail company (SNCF). The only Parisian SNCF station not to be directly connected to the RER is the Gare Montparnasse.
