Giant breakdown on the RER B
This incident comes two days after a giant blackout on line B (the second busiest in Europe). “Cables were damaged during a construction incident that occurred this morning around 9am in the town of Aubervilliers as part of modernization work on the RER B”, indicated Monday SNCF Réseau.
A SNCF Réseau service provider had damaged signaling and telecommunications cables as part of the work currently being carried out for “cut the network” and create isolated catenary sections so that an incident does not spread down the line, the company said.
