O2D programme: a new lease of life for high-speed trains

This programme heralds a new era for the TGV fleet. Faced with the opening up to competition and the ecological transition, it extends the service life of 104 trainsets by up to 10 years, combining industrial performance, sobriety and passenger comfort.

Designed for passengers and the planet, it is at the heart of SNCF Voyageurs' environmental strategy. Based on the circular economy, it relies on the reuse of parts from retired trains, reducing new purchases, waste and the carbon footprint.

It is a collective project, driven by a multi-site, multi-trade synergy bringing together engineering, the supply chain (supply management), purchasing (setting up contracts and managing suppliers), production, industrial Technicentres and maintenance Technicentre (preparing for production and industrialisation).

The renovated trains consume less energy, improve accessibility and enhance the overall performance of the TGV fleet, for the benefit of passengers.

With O2D, SNCF Voyageurs is including the management of its rolling stock in a fully operational circular economy logic. The written-off trainsets become real "parts banks", reducing costs, waste and the carbon footprint of the rail industry, with over 84,000 tonnes of CO₂ already avoided. Piloted at Ambronay and set to be rolled out at other sites such as Grémonville, this sustainable approach prefigures a new industrial standard for other types of rolling stock projects.

With this programme to extend the life of TGVs, the rail industry is speeding up its technological transformation. The gradual integration of the TGV M version of theERTMS (European Rail Traffic Management System) by 2030 will improve the fluidity and safety of traffic across Europe, while increasing line capacity.
