96 additional RER NGs for the RER D line

On 23 June 2025, Alstom announced that it will supply SNCF Voyageurs with 96 additional RER NG EMUs for the RER D line in order to complete and renew the fleet on the latter. This order, formalised by SNCF Voyageurs, follows the vote on the financing agreement by Île-de-France Mobilités Board of Directors on 10 April 2025.

Financed at 100 % by Île-de-France Mobilités, this order worth around 1.7 billion EUR is part of the framework agreement signed in 2017 between SNCF Voyageurs and Alstom. To date, 166 RER NGs have already been ordered. This new order brings the total number of units to 262 (130 trainsets, each 112 m long, for RER E and 132 trainsets, each 130 m long, for RER D). 

The New Generation RER (called “RER NG”) is a double-decker rolling stock designed for the RER D and RER E lines, operated by Transilien SNCF Voyageurs on behalf of Île-de-France Mobilités, in order to improve passenger comfort and regularity on these lines. RER NG has been running on the RER E line since November 2023 and on the RER D line since December 2024. 

Key figures for RER NG for the RER D line:

A maximum speed of 140 km/h
130 m long for a 7-car trainset
1,861 places, including 606 seats
More than 320 km of cables
More than 310 USB ports 
54 information screens
54 surveillance cameras

The Alstom sites at Valenciennes-Petite Forêt and Crespin, in Hauts-de-France, are responsible for designing and assembling the trainsets, with the participation of various French sites manufacturing components (Ornans, Tarbes, Le Creusot, Petit-Quevilly, Villeurbanne) and the Saint-Ouen site for design.
