RER E and D: the new “NG” trains undergoing testing

The two RER D and RER E lines will receive 255 new trains, which are starting their testing at stations alongside the start of service in October.

All types of transportation are progressing rapidly. Whether it’s the new metros in Paris, the tramway in Nantes or the future TGV M, no mode is overlooked, not even the classic RER. The Île-de-France regional express network will soon receive 255 new trains on lines RER D and E. They are called “NG” for New Generation.

The latest tests of the NG RER trains began last weekend, February 18 and 19, 2023. Slightly disrupting traffic at Gare de l’Est in Paris, the trains conducted platform tests to verify cameras, accessibility for persons with reduced mobility, door openings, and signaling. This will continue until October along the RER E route.

Then, train testing will commence in spring on the RER D line between Paris and Combes-la-Ville. They will carry out similar tests, as well as “integration trials and staff training,” indicates IDF Mobilités. Operating during the day with two open-to-public trains, the NG RER trains will run empty. These exercises are expected to conclude by early 2024 at the latest.

When will the new trains on RER E and D operate?

These new-generation trains will only arrive in October 2023 on RER E. This line will have 125 trains, each with 6 carriages. For RER D passengers, it will be necessary to wait until spring 2024, with 130 trains planned, each with 7 carriages. Île-de-France Mobilités promises better comfort, increased accessibility for all, climate-controlled heating/air conditioning, and 300 USB ports in the trains.
