Alstom has confirmed an order for 96 additional RER New Generation (RER NG) trains to be delivered to SNCF Voyageurs for operation on the RER D line.
The order, worth approximately 1.7 billion EUR and financed entirely by Île-de-France Mobilités, follows a vote by the authority’s board in April 2025.

This latest procurement brings the total number of RER NG trainsets ordered to 262, under a framework agreement signed in 2017. Alstom is supplying two variants of the train: 130-metre long, 7-car trainsets for the RER D line, and 112-metre long versions for the RER E.
RER NG trains have been in service on the RER E line since November 2023 and on RER D since December 2024. This new tranche of vehicles will allow Île-de-France to both expand and modernise its commuter rail offering, supporting higher capacity and an improved passenger experience on one of the region’s most heavily used lines.
Frédéric Wiscart, President of Alstom France said:Alstom is delighted with this announcement, which confirms the confidence of Île-de-France Mobilités and SNCF Voyageurs in this new and innovative rolling stock, designed and assembled at our Valenciennes and Crespin sites, in the North of France.
The double-decker RER NG features a fully open boa architecture, combining single- and double-deck cars with wide doors to speed up boarding and alighting. Each train includes level-access areas for wheelchair users and multiple distinct passenger zones.
Comfort features include:
- Air conditioning
- Dynamic LED lighting
- Over 310 USB charging ports
- 54 passenger information screens
- 54 security cameras
- Seats optimised for long-distance commuter travel
Technologically, the trainsets are equipped with Alstom’s latest traction systems, delivering better acceleration and braking, which is a key advantage on high-frequency urban lines.
Each 130-metre trainset for the RER D will have the capacity for 1,861 passengers, including 606 seated. More than 320 kilometres of cabling run through each train, underlining the complexity of the onboard systems.
The trains are being designed and assembled at Alstom’s sites in Valenciennes-Petite Forêt and Crespin in northern France, with components supplied by facilities in Ornans, Tarbes, Le Creusot, Petit-Quevilly, Villeurbanne, and Saint-Ouen. This widespread domestic supply chain supports jobs and expertise across multiple regions.
