The inauguration of this 17,000 m² maintenance workshop marks a key step before the line becomes operational. It will be crucial for servicing 40 of the 130 Eole trains. The presence of numerous project stakeholders, including Pierre BÉDIER, president of the Department of Yvelines, highlighted the event's significance.
The Department, investing €338 million, is a major player alongside the State, the Île-de-France Region, the Société du Grand Paris, and other authorities. This project aims to meet residents' travel needs and is expected to serve over 650,000 daily passengers between Mantes-la-Jolie, Paris, and Tournan-en-Brie.
Pierre BÉDIER described the Eole project as a "historic change" for the people of Yvelines, signaling a renewal for the Seine valley and boosting its attractiveness.
The Mantes-la-Jolie maintenance workshop, operational for a few weeks, will handle the garaging, maintenance, cleaning, and preparation of the trains. It will operate 24/7 and eventually employ 230 staff. The facility is eco-designed, incorporating photovoltaic panels and rainwater harvesting.
The RER E extension to Mantes-la-Jolie will include 10 stations in the Yvelines, a travel time of 40 minutes between Mantes-la-Jolie and La Défense, and will enhance interconnections with other Île-de-France transport lines.
