Autonomous trains are coming soon. SNCF plans to circulate fully automated prototypes by 2023, thanks to a partnership involving, among others, the Alstom and Bombardier railway builders. "This allows you to move more trains but also to save energy, which also gives you greater flexibility: you can decide at the last minute to add a train, for example, it's a real revolution in our transport. ", said Henri Poupart-Lafarge, boss of Alstom, Thursday evening in the eco-guest Emmanuel Duteil, on Europe 1.

"This poses a lot of questions about security." Henri Poupart-Lafarge explained the difficulties of developing autonomous trains, especially for safety reasons. "The future is for autonomy, it's very good news, we've been working on autonomous metros for a few years now, and we're moving to a new stage." The subway is in a limited and constrained universe. him on an open world, in which it can happen a lot of things.This raises a lot of questions at once of security and anticipation, which have no place to be in the metro ", has-it- he detailed.

But the boss of Alstom was reassured about the safety of these future trains. "Autonomous does not mean necessarily without a driver, there is obviously a surveillance of the way.If the wild boars must cross the voice, the train will recognize them," he says. "Industrially, the door will open for autonomous trains from 2025" predicted Pierre Izard, the deputy general manager in charge of railway technologies at SNCF.

The hydrogen train, "a world first". Henri Poupart-Lafarge also returned to the hydrogen trains, produced by Alstom and whose first model will be put into service this weekend in Germany.

"The hydrogen train is a world first The environment is at the heart of our concerns 50% of the lines today are not electrified There is a very strong challenge to find an alternative to diesel on these lines The cost of electrification is very high, so it does not pollute, and divide the costs by 4. The goal is not to pollute, but also to significantly reduce the degree of CO2 emission.
