An extraordinary board of directors of Ile-de-France Mobilités is summoned Tuesday to lift doubts about the future of the Nexteo project. In question: risks of additional costs around the semi-automation of lines B and D of the RER.

The dramatic coup intervened on Wednesday July 20. That day, Luc Lallemand, CEO of SNCF Network since March 1, 2020, meets the president (free!) Of the Ile-de-France region, Valérie Pécresse. The Belgian, follower of the outspokenness, does not go there by four paths: he wishes to warn him that he cannot, as it stand, launch the last act of the call for tenders of Nexteo, this Project at 1 billion euros intended to modernize lines B and D of the RER by 2030. There are strong technological risks around the semi-automation of these lines, and, by extension, the risks of additional costs. For him, it is urgent to assess them before asking manufacturers to give their last price.
The new goes badly in the region. Valérie Pécresse is improving everyday transport to make her second term a success. However, on these lines, which carry two, 1.6 million travelers, every new delay daily, is explosive. At the end of the summer, the elected official convened an extraordinary board of directors of Ile-de-France Mobilités (IDFM), the Organizing Transport Authority, for Tuesday September 13, and sum the CEO of SNCF network of come and explain it.
“The call for tenders has already been launched a year late, in 2020. The contract was to be signed at the end of this year, regrets Laurent Probst, the director general of IDFM. Finding yourself, in 2030, without semi -automation of the largest line in Europe. “François Durovray, President Les Républicains (LR) of Essonne – department served by the two lines – and administrator of IDFM, is more direct : “Either Luc Lallemand brings explanations, or he is no longer able to direct SNCF Network.”
Nexteo is a new trains for trains as ambitious as it is Essentiel, necessary to improve traffic conditions on lines B and D of the RER. Passengers in these north-south-south lines in the Paris region today live hell. They no longer have delays, incidents, repeated traffic interruptions. In short, what the passengers of line A of RER lived before ten years of work changed the game. In 2016, IDFM presented a program at 7 billion euros for these lines: new trains, an infrastructure (catenaries, referral stations), and this technology, Nexteo which makes it possible to circulate more trains.
Three major difficulties
This new fever of fever between IDFM and SNCF Network reveals three major difficulties. The first puzzle is technological. The inauguration with great fanfare, Monday, September 12, of three automatic shuttles on line 4 of the metro could suggest that the semi-automation of RER B and D is at hand. But this leap forward is much easier to make on a line circulating in a tunnel or on a dedicated network than for trains which circulate in the so -called “open” environment.
