Users of the northern section of RER B are asked to travel as little as possible between 12 and 14 August. Their line will be closed for work and replacement buses will not be enough to absorb demand.
SNCF mobilized 600 buses and 1,000 drivers with a cadence of up to one departure every 40 seconds at Aulnay-sous-Bois station. The work consists of installing turning tracks north of Paris and runs from Gare du Nord to Paris-Charles de Gaulle Airport.
