A night of hardship in prospect for RER B users. Traffic between Gare du Nord and Aulnay-sous-Bois (Seine-Saint-Denis) is interrupted due to a failure of a rare magnitude. “Cables were damaged during a construction incident that occurred this morning around 9 am in the town of Aubervilliers as part of modernization work on the RER B”, the second busiest suburban train line in Europe after line A, said SNCF Réseau, track manager.
Nearly a million people use the line every day (apart from the pandemic), on which operating incidents are almost daily, especially as the CDG Express site – a high-speed train to link the center of Paris to Paris in 2025. Roissy / Charles-de-Gaulle airport – complicates the situation in the north of Paris.
Resumption around 8 p.m.
An SNCF Réseau service provider damaged signaling and telecommunications cables as part of the work currently being carried out to “cut up the network” and create isolated catenary sections so that an incident does not spread over the entire line, SNCF Réseau specified. “All means are being implemented to restore circulation as quickly as possible”. The RATP and the RER B Twitter account indicate a resumption of traffic around 8:00 p.m.
SNCF and RATP recommend consulting the possible alternative routes on the site rerb-leblog.fr.
