COLAS RAIL AND TSO CATENAIRES continue the industrialisation of catenary regeneration with the 1,500 V high output renewal train

The 1,500 V high output catenary renewal train developed for SNCF Réseau by COLAS RAIL, TSO CATÉNAIRES and the manufacturers Geismar and Novium, has been proving its effectiveness since January 2022 on a new project carried out between Fleury-les-Aubrais and Beaugency.

Put into production in June 2021, the 1,500 V high output catenary renewal train is unique worldwide. It is based on two very innovative specific factory trains and on industrial iso picketing, a concept unpublished until then in the renovation of catenaries.

The progress report on the work in progress in Loiret, on the railway line linking Fleury-les- Aubrais station to Beaugency station, is very positive. It confirms that this high output
renewal train makes it possible to regenerate 1,500 V electrified lines on a large scale thanks to significant productivity gains compared to conventional renovation (the intervention time is divided by 4).

The 1500 V high output catenary renewal train also enhances the safety and quality of work, which is further characterised by great attention to social and environmental responsibility. With this second high output renewal train, as with the 25,000 V high output renewal train which has been in operation since 2019, COLAS RAIL and TSO CATÉNAIRES, united as an
integrated consortium, continue to successfully implement the 2019-2026 catenary renovation programme launched for SNCF Réseau, including achieving 100% of performance goals set by their client. In 2022, 1,500 catenary supports and their fittings should be renovated using the 1,500 V high output renewal train.

On the Fleury-les-Aubrais/Beaugency site, COLAS RAIL, TSO CATÉNAIRES and SNCF Réseau are also asserting their partnership dynamic. This partnership, which has been based from the outset on close collaboration, extreme standards and a continuous improvement approach, contributes to the emergence of new levers of progress to meet the future needs of catenary renovation.

Key figures to remember:

• 1 unique high output renewal train worldwide
• 1500 catenary supports and fittings to be regenerated in 2022
• A renovation 4 times faster than with conventional renovation tools and methods
