| RER network|
Mini Biography |
The Reseau Express Regional colloquially called the RER, is a hybrid suburban commuter:rapid transit system serving Paris, France and its suburbs.
The RER combines the operations and roles of a local city centre underground rail system and suburbs to city center commuter rail.
Inside the city center, the RER functions much like the Metro, but is faster as it has fewer stops.
This has made it a model for proposals to improve transit within other cities.The network consists of five lines: A, B, C, D and E
and has several connections with the Paris Metro within the city of Paris.
The lines are identified by letters to avoid confusion with the Metro lines, which are identified by numbers.
The RER is still expanding: Line E, which opened in 1999, is planned for westward extension in two phases by 2020–2021.
