[FR] X’Trapolis Cityduplex: the new Paris RER trains from Bombardier and Alstom

At its board meeting, SNCF selected the Alstom-Bombardier consortium to renew the trains on lines D and E of the Île-de-France network.This contract for 255 trains (130 for the RER D and 125 for the RER E), worth an estimated 3.75 billion euros, is the largest contract ever financed by STIF.

For Valérie Pécresse, President of the Île-de-France Region and of STIF, “(..) More than 700 trains will be purchased or renovated to modernize the existing rolling stock, which is on average over 30 years old. (..) From 2021 onwards, they will discover a new generation of trains, safer and more reliable as well as more comfortable and regular. The order will also have a positive effect on the rest of the network: 15% of RER A traffic will be transferred to line E, which will be extended to Nanterre in 2022, then as far as Mantes-la-Jolie in 2024.”

Alstom, in partnership with Bombardier, will design and supply the new generation of two-tier equipment for lines D and E of the Île-de-France network, which is operated by SNCF Transilien.

Tier 1: 56 trains 112m long and 15 trains 130m long
This first part of the contract has a value of 1.55 billion euro, 100% funded by STIF. This amount includes all design studies, industrialisation, project management and homologation for a value of 450 million euros. These first 71 trains will enter circulation from 2021 onwards. The Alstom-Bombardier consortium’s share for this first part of the contract is worth 1.155 billion euros, to be booked in January 2017 (approximately 70% Alstom – 30% Bombardier).

The X’Trapolis Cityduplex: An open train with different zones
The new train design is baptised ‘X’Trapolis Cityduplex’. It is entirely open (without separations between the cars) and was specifically designed for the dense zones of traffic in Île-de-France. Thanks to its large doors, the train provides extremely fluid passenger exits and entrances as well as offering three distinct travel spaces. Passengers can thus choose their space according to their journey time: platform zones for travelling standing-up when the journey is very short, making it easy to move around, like in the metro; mixed-use zones (standing or sitting) located lower down for journeys under 20 minutes, and higher up, areas offering regional-style comfort with more seating for longer trips. In each of the end cars, platforms provide wheelchair users with direct and quick access to dedicated spaces. Air conditioning, lighting and seating have all been designed to provide a high level of comfort.

Each train can transport up to 1860 passengers (130m version). Numerous innovations will reduce energy consumption by 25% compared to previous generations of equipment. The train contains 8 motor bogies to provide superior performance compared to previous generations in terms of acceleration and deceleration with regenerative braking, an undeniable asset for exploitation.

8 Alstom factories, 1 Bombardier
To carry out this major project successfully, a total of around 2,000 people will work on the project under the Alstom-Bombardier consortium, including 550 experienced engineers, securing more than 8,000 jobs in the French rail sector. Eight Alstom sites in France will be responsible for designing and manufacturing the new equipment: Valenciennes for the project management, design, validation, tests, commissioning and warranty, end vehicle production and final train integration; Reichshoffen for the studies, Ornans for the engines, Le Creusot for the bogies, Villeurbanne for the on-board electronics, Tarbes for the traction systems, Petit-Quevilly for the transformers and Saint Ouen for the design. The Bombardier site in Crespin will be responsible for designing and manufacturing the intermediate cars.
