en.Wedoany.com Reported - Launched under the France 2030 investment plan with support from the French Environment and Energy Management Agency (Ademe), the French EcoTrain project aims to develop a new generation of lighter, electric, and autonomous rail structures. The project focuses on lightweight shuttle trains for low-density secondary and regional lines, seeking to provide decarbonized rail transport options for existing infrastructure constrained by economic operating costs.

The project brings together several French industrial and academic partners, including Socofer, Stratiforme Industries, Clearsy, Syntony GNSS, IMT Nord Europe, and IMT Mines Albi. Stratiforme is involved in all stages of developing composite carriage structures, covering engineering and design, material selection, manufacturing, and onboard system integration.

"The overall logic of the project is to lightweight structures, reduce operating costs, limit impacts on infrastructure, and use materials with minimal environmental impact," said Pierre Berdzinski, Engineering Project and R&D Manager at Stratiforme Industries. Reducing the mass of railway vehicles has become a key driver for lowering energy consumption, reducing lifecycle CO2 emissions, and limiting infrastructure maintenance costs.

The use of composites is a major innovation of the project. In the railway industry, composites are typically used for secondary applications such as decorative panels, trim, fairings, or interior fittings. EcoTrain integrates composites into the carriage structure, not merely replacing existing materials with new ones, but rethinking the overall vehicle architecture to optimize cost, weight, and lifecycle.
