Major RER B and D Service Disruptions

Significant summer works are impacting the RER network until August 16. RER B service is suspended between Gare du Nord and La Croix-de-Berny/Robinson, while RER D is cut between Gare du Nord and Gare de Lyon.

Why this matters to travelers

Travelers to CDG airport face reduced train frequency and crowding; those using RER D must use Metro Line 14 or RER E as alternatives.
