PARIS RER line B will have a new timetable from September 13 that has been developed in consultation with elected officials and passenger associations.
The 80km north-south line is seen as a major challenge for Paris Transport Authority (RATP), French National Railways (SNCF) and Île-de-France Mobilités, with a desire to improve performance so that it meets the expectations of the users.
A more robust operation will be possible following a two-year project to improve flexibility on the line and offer a more frequent service at the busiest times, as well as being able to adapt the service to the changes in usage at certain stations.
More trains will now stop during peak-times at Gentilly and Laplace. These will be served by 20 trains per hour instead of 15. At Arcueil-Cachan and Bagneux there will be 20 trains per hour instead of 10 previously while La Croix de Berny, Palaiseau and Le Guichet stations will all have 10 trains per hour compared with the previous five.
The southbound peak period has been extended to 09:00 instead of 08:30 while in the evening it now begins at 17:40 instead of 18:10.
An additional 10 trains will be extended: to Massy with an hourly extension of the service caused by a later start to the night period at 22:40 instead of 21:40, and to Saint-Rémy-lès-Chevreuse with an increased frequency of one train every 15 minutes until 23:50, instead of 21:50 as before.
Longer trains will also be used until the end of service on Friday, Saturday and Sunday.
The timetable changes are part of modernisation plan for Line B that aims to offer the same quality as those on Line A.
