Hybrid suburban commuter and rapid transit system serving Paris, France and its suburbs. From Wikipedia, the free encyclopedia
RER B is one of the five lines in the Réseau Express Régional (English: Regional Express Network), a hybrid commuter rail and rapid transit system serving Paris, France and its Île-de-France suburbs. The 80-kilometre (50 mi) RER B line crosses the region from north to south, with all trains serving a group of stations in central Paris, before branching out towards the ends of the line.
The line opened in stages starting in December 1977 by connecting two existing suburban commuter rail lines with a new tunnel under Paris: the Chemin de Fer du Nord to the north (which formerly terminated at Gare du Nord) and the Ligne de Sceaux to the south (which formerly terminated at Luxembourg station).
The RER B, along with the rest of the RER network, has had a significant social impact on Paris and the surrounding region by speeding up trips across central Paris, by making far fewer stops than the Paris Métro and by bringing far-flung suburbs within easy reach of the city centre. The line has far exceeded all traffic expectations, with passengers taking 165 million journeys per year in 2004. That makes the RER B the second busiest single rail line in Europe (after RER A).
The line faces capacity challenges as a result of sharing a tunnel with RER D trains between Châtelet–Les Halles and Gare du Nord.

The RER B Line has two service patterns:
In any case, the stations from Cité Universitaire to Paris Gare du Nord are served by every single train.
In 2021, the off-peak service is made up of 3 missions per 1 / 4H:
To the south:
To the north:
Rush hour is between 07:00 and 09:45 in the morning and between 16:00 and 20:00 in the afternoon.
In 2021 the rush hour service is made up of 4 missions per 1 / 4H:
In the northern section after Paris Gare du Nord, all trains are local trains.
To the south:
To the north:
In the northern section after Paris Gare du Nord, all trains are local trains.
Some infrequent missions can be seen such as missions J to Denfert Rochereau in the evening.
RER B mission codes are made up of four letters followed by two numbers. The first letter always indicates the destination.

RER B is operated by 117 sets of the MI 79 series and 31 sets of the MI 84 series. These are to be replaced from 2025 by the MI 20 series.[1]
Past fleet include the MS 61, which operated on the line from 29 June 1967 to 28 February 1983, and the Class Z 23000, which operated from 16 November 1937 to 27 February 1987.
As part of the Grand Paris public works program, the creation of a new infill station called "Aérofret" between Parc des Expositions station to the south and Aéroport Charles de Gaulle 1 station to the north was proposed. The new station would be located adjacent to and serve the Aéroville mall as well as planned development on the western side of the freight areas on the western side of Charles de Gaulle Airport. It is slated to open by 2025 along with the planned developments in the area.[2]
Already proposed in the 1994 Schéma directeur de la région Île-de-France (Île-de-France regional development plan, SDRIF), but without any concrete plans ten years later,[3] the project to extend RER B northeast from Mitry–Claye station to the Dammartin-en-Goële area, serving intermediate stations at Compans and Thieux-Nantouillet, is proposed in Phase 3 (horizon 2021-2027) of the revised SDRIF, adopted by deliberation of the Regional Council of Île-de-France on September 25, 2008.[4] It would also involve the creation of a new terminus station located in the neighboring commune of Rouvres, some 3.5 km (2.2 mi) north of the current Dammartin Juilly Saint-Mard station near Saint-Mard, which is old and unsuitable for such a project.[5] The project is now expected to be completed around 2030.
