The RER B is one of the five lines in the RER rapid transit system serving Paris, France.
Built from 1842 and opened on 7 June 1846, the station building had a circular shape as it possessed a rail loop. Indeed, the station was the Parisian terminus of a line from Sceaux. This Ligne de Sceaux system, named "Arnoux" (after its inventor), was abandoned at the end of the 19th century as it required the construction of specific engines capable of travelling on very tight curves and broad gauge tracks of 1,750 mm (5 ft 8 7⁄8 in). The line was extended to the Gare du Luxembourg in 1895, with the newly created Port-Royal station along the way. The line was operated by the Chemin de Fer de Paris à Orléans until 1937 when the Compagnie du Chemin de Fer Métropolitain de Paris (CMP) (predecessor of the RATP) took over. It became line B of the RER in 1977 on being extended to meet line A at Châtelet – Les Halles.
Sceaux is a commune in the southern suburbs of Paris, France. It is located 9.7 km (6.0 mi) from the center of Paris.
"La Ligne de Sceaux" was a railway line in France running from Paris to some of its southern suburbs, including Sceaux from which it takes its name. It is now part of the RATP's RER line B, though the name is still used informally.
Port-Royal is a railway station on the RER B in Paris, France. It is situated on the border of 5th and 6th arrondissement of Paris, and named after the convent of Port-Royal.
The station building of Denfert-Rochereau station is the oldest railway building still standing in Paris.
Denfert-Rochereau remains a station of line B of the Réseau Express Régional and is an interchange with the métro station of the same name, Station Denfert-Rochereau.
The Réseau Express Régional, commonly abbreviated 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 Métro, 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. The network has 257 stations and has several connections with the Paris Métro within the city of Paris. The lines are identified by letters to avoid confusion with the Métro 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 2020–2022.
Denfert-Rochereau is a station on the Paris Métro in France. An adjacent station with the same name is served by RER B.
