After a wave of projects in the Hauts-de-France region, SNCF Réseau is announcing the work planned for May in the Île-De-France region. In 2023, around 2 billion euro worth of work will be carried out on the Ile-de-France network, including 800 million dedicated to regeneration operations. Here are the interruptions to be expected on the Eastern and Atlantic axes in the Ile-de-France region.

SNCF Réseau is taking advantage of the drop in public transport ridership during the weekends in May to carry out operations that require traffic to be interrupted throughout France. In total, 101 switches and 163 kilometres of track will be renewed throughout the year.

On the East Axis

Signalling

During the weekend of 13 to 14 May, SNCF Réseau will test the entire future signalling system that will eventually manage the 3,000 trains on the East/West axis in the Paris region. In addition, SNCF Réseau will test the telecommunications, signalling and passenger information connections with the single East/West command centre at Pantin. This marks the first stage of the EOLE project, comprising 640 points, 700 signal lights, 6 test trains and 300 train paths. A second stage is planned for June, involving the technical deployment and initial testing of the 8 kilometres of new infrastructure between Haussmann Saint-Lazare and Nanterre.

Stations and Trains

During the weekend of 6 May, SNCF Réseau will continue to carry out preparatory work on the structures associated with the future Bry-Villiers-Champigny interconnection station. This future station will link lines E and P to the future line 15 of the Grand Paris Express.

There will also be work on the Eastern network which will affect some TGVs and TERs on the weekends of 13 and 14 May. After the tests are carried out on the East/West Ile-de-France axis, TER trains will be welcomed at Austerlitz station and TGVs at Paris Nord station.

Between Gare de l’Est and Noisy-le-Sec, SNCF Réseau will replace 13 kilometres of rails using BOA factory train technology on lines E and P on the weekends of 27 to 29 May. This train can renew 320 metres of rail per hour, i.e. 2 to 3 times faster than the conventional method.

RER C

Two projects for the RER C will move forward in May. Firstly, the rail bypass of southern Paris will take place on the weekends of 1 and 18 May. RER B and C trains, as well as TGVs, cross each other every day between Massy and Antony, causing conflicts between the various trains. The aim of the work is to eliminate this “shearing” in order to increase the number of TGVs while guaranteeing the regularity of line C.

Secondly, the regeneration of the southern part of line C will take place on the weekends of 6, 20 and 27 May. It includes a catenary regeneration operation between Athis-Mons and Choisy-le-Roi and the replacement of the track and ballast over a distance of 1 kilometre at the Ardoines station.

On the Atlantic Axis

SNCF Réseau is planning to carry out modernisation work on the Atlantic Axis high-speed line during the weekends of 18 and 27 May. The communes of Massy, Palaiseau, Antony and Verrières-le-Buisson will be affected by the renewal of 8 switches and 7,000 metres of track. This work will lead to adjustments on the Atlantic axis. TGVs heading for the Centre and New Aquitaine regions will leave from and arrive at Austerlitz station (and not Paris Montparnasse), with a journey time extended by 30 minutes. In addition, TGVs from and to the West (Brittany and Pays de la Loire) will arrive at Montparnasse station with a journey time of approximately 1 hour to 1.5 hours.

RER D

To prepare for the arrival of the new generation RER (RER NG), catenary reinforcement work will be carried out between Grigny and Evry-Courcouronnes, Ris Orangis and Corbeil-Essonnes on the RER D over the weekend of 8 May.

Line J

On line J, track work will be carried out between Epône-Mézières and Mantes-la-Jolie on the weekends of 1 and 6 May. This preparatory work for the lightning operation that will take place this summer includes the installation of computerised signal boxes and track replacements between Epône and the Limay rail bridge. They concern the computerised signal box (PAI 44) at Epône, which will be brought into service in 2025, and the connection of the 3rd track between Epône and Mantes-La-Jolie.
