On 6 May, the RER E line extension between Saint-Lazare station and Nanterre opened in the western suburbs of Paris.
With this extension, the line now serves three new stations: Porte Maillot, La Défense-Grande Arche and Nanterre-la-Folie across an additional 8 kilometres of line.
The new stations feature high ceilings, natural light, widened platforms, and modern accessible equipment. They also offer numerous connections with the rest of the network, including the RER A, lines L, U, P, metro 1, and trams T2 and T3b.
This extension aims to improve transport services in the west of the Île-de-France region.
From 2026, the line will also span further west to Mantes-la-Jolie, which will be the final terminus.
The line will be served by new RER NG trains. Initially, 4 trains per hour will operate from 10am to 4pm between Nanterre La Folie and Magenta. Once additional rolling stock is delivered, a normal service is expected to be achieved by the end of 2024.
