The line runs from the northern termini Aéroport Charles de Gaulle (B3) and Mitry-Claye (B5) to the southern termini Robinson (B2) and Saint-Rémy-lès-Chevreuse (B4).

  • First opened : 9 December 1977
  • Length : 80.0 km (49.7 mi)
  • Number of stops : 47
  • Traffic (2004) : 165 million journeys per annum (figure only for the RATP section of the line)

The southern part of the line (south of Gare du Nord) is operated by the RATP, and the northern part by the SNCF. Trains are owned by either company.

Until December 2009, drivers changed at Gare du Nord; RATP and SNCF drivers now operate their trains along the full length of the line. Trains moving from one network to the other at this station is known as the Interconnexion.

Technical difficulties of the Interconnexion include the shared tunnel with RER D between Châtelet – Les Halles and Gare du Nord, and the fact that while the SNCF part in the northern suburbs use 25 kV AC, the RATP part uses 1500 V DC, forcing the use of dual-voltage trains.

ChronologyEdit

Line B was the product of the connection in 1977 of the Ligne de Sceaux terminus, Luxembourg, with the Gare du Nord via Châtelet – Les Halles. In 1988 St-Michel – Notre-Dame station between Luxembourg and Châtelet – Les Halles was opened to provide connection with RER C and Métro Line 10 at Cluny – La Sorbonne, a station which had been closed since the beginning of World War II and was entirely renovated for the occasion.
