Renovation of platform 3 in the Denfert-Rochereau RER station

From October 2013 to December 2014, construction work will be conducted within the Denfert-Rochereau RER B station, in order to renovate platform 3.

In the event that service is disrupted on the RER B’s central section, this platform will enable passengers arriving from the south to access the Denfert-Rochereau connection hub and to continue their journey.

This renovation project is part of the RER B master plan decided by STIF, the Organising Authority for public transport in the Paris Île-de-France region, in association with the French State and the Île-de-France region. The master plan aims to improve regularity, manage disturbances and enhance passenger comfort on RER B.

The renovation of the platform will cost €7.3m, of which 30% is financed by the French State and 70% by the Ile-de-France region..

Built in 1842, Denfert-Rochereau is Paris’ oldest train station. It is listed as a historical monument.


Platform 3, which was used until recently to park trains and did not handle any passengers, has existed in this configuration since 1937.

Between 1930 and 1987

Track 3 and platform 3 were both in use. The station’s current configuration was created during line electrification in 1937. The platform canopy dates from this period.

Before October 2013

Track 3 was used to park trains, and tracks 5 and 7 for parking construction engines. The platform canopy was still in place.

Track 3 will serve as a terminus station for trains when there are service disruptions north of the line. Tracks 5 and 7 will be eliminated and replaced by a landscaped setting. A passenger exit that is accessible solely during service disruptions will open onto rue Jean-Claude Arnould. The platform canopy will be renovated.
