RER NG enters commercial service on the RER D Line

The fourth generation of Alstom’s RER rolling stock, the RER NG, enters into commercial service on the RER D Line of the Île-de-France Mobilités network. One year after its gradual deployment on the RER E Line, RER NG is welcoming its first passengers and has been gradually deployed on the RER D Line since 16 December 2024. Since 15 December 2024, RER NG has also provided a full service on the entire RER E Line.

“The deployment of RER NG on the RER D Line marks a major milestone for transport in the Île-de-France region and for Alstom. RER NG embodies the commitment of Alstom’s teams to ever more sustainable mobility at the service of passengers,” said Henri Poupart-Lafarge, CEO of Alstom. “We are delighted to be able to offer Île-de-France citizen a modern, comfortable and high-performance train that will transform the quality of their travels over the long term. Our teams remain strongly mobilised alongside SNCF Voyageurs and Île-de-France Mobilités to guarantee a service that meets the expectations of local passengers”.

Fully financed by Île-de-France Mobilités, the “New Generation” RER is a double-decker rolling stock designed for the RER D and E Lines, both operated by Transilien SNCF Voyageurs on behalf of Île-de-France Mobilités, in order to improve passenger comfort and regularity on these lines.

This train has been designed, both in terms of architecture and interior design, to optimise capacity and passenger flow. Thanks to its entirely open architecture (“boa” architecture) and wide doors, it allows passengers to enter and leave the train with ease. It offers distinct travel areas designed to meet the needs of all types of journeys made by the people of Ile-de-France and adapted to their travel times: spacious vestibules for standing passengers on short journeys, upper-deck lounges with more seats for longer journeys and lower-deck rooms that are mixed (standing and seated), designed for journeys of less than 20 minutes.

The new trains offers more comfort, with air-conditioning, LED lighting adapted to the different times of the journey (day/night/station stops), USB sockets and numerous screens giving passengers rapid access to various transport information. Particular attention has also been paid to the ergonomics of the seats.

Based on Alstom’s urban and suburban rolling stock solutions, RER NG has been designed to guarantee the highest levels of availability, reliability and safety. RER NG has eight motor bogies, providing higher acceleration and deceleration performance than previous generations of rolling stock, which is an undeniable advantage for operations.

RER NG is the result of close collaboration between Alstom, SNCF Voyageurs and Île-de-France Mobilités teams throughout the project.

The train was designed and is assembled at Alstom’s Valenciennes-Petite Forêt and Crespin sites, with the participation of various French component manufacturing sites (Ornans, Tarbes, Le Creusot, Petit-Quevilly, Villeurbanne) and the Saint-Ouen site for the design.
