RER NG
The RER NG (French: RER Nouvelle Génération, lit. 'RER New Generation'), also known as the X'Trapolis Cityduplex and classified as Class Z 58000 and Class Z 58500, is a double-deck, dual-voltage electric multiple unit trainset operating on line D and line E of the Réseau Express Régional (RER), a hybrid suburban commuter and rapid transit system serving Paris and its Île-de-France suburbs. The trainsets entered service in November 2023 on line E, and in December 2024 on line D.
The trainsets are manufactured by a consortium of French company Alstom and Canadian company Bombardier Transportation. The RER NG is part of Alstom's X'Trapolis Duplex platform and is a development of previous double-deck trainsets built by the consortium, including the Z 2N, MI 2N, and MI 09 series.
Final assembly takes place at Alstom's factory in Valenciennes and the former Bombardier plant in Crespin, while the car bodies are manufactured at Alstom's plant in Česká Lípa, Czech Republic.
As Île-de-France Mobilités and SNCF prepared to extend the RER E line west across Paris, the agencies issued an invitation to tender for new trainsets for the line and overall fleet replacement. Several manufacturers responded including a consortium of Alstom and Bombardier, CAF, and Siemens.
Ultimately, the €3.75 billion contract was awarded to Alstom and Bombardier on 6 January 2017. The consortium had previously built several generations of double-deck trainsets, including the Z 2N, MI 2N, and MI 09 series. Similar to those earlier contracts, Alstom would build the two end cars, which contain the cabs, while Bombardier manufactured the intermediate cars. The contract will supply 255 trainsets, 130 for the RER E and 125 for fleet replacement, which are planned to be assigned to the RER D, replacing older trainsets.
In October 2018, Île-de-France Mobilités purchased an additional 64 trainsets for fleet replacement, increasing the total contract to 371 trainsets.
In spring 2020, the first trainset started testing in the Czech Republic.
On April 26, 2023, Alstom announced the exercise of a first option for the supply of 60 additional trainsets, bringing orders to 131 trainsets.
