The joint project targets the front parts of locomotives, specifically the cowcatchers which are prone to external damage such as impact. These parts are currently responsible for frequent maintenance interventions and replacement resources.

By introducing CompPair’s innovative regenerative composite technology, the partnership aims to demonstrate a significant reduction in maintenance operations and extend the service life of affected parts. This solution enables in-situ repairs, allowing damaged composite components to be healed in minutes, thus reducing downtime and improving cost-efficiency.

“Our goal is to showcase how advanced materials can make a tangible economic and ecological difference in the daily operations of the rail industry,” said Amaël Cohades, CEO of CompPair. “We’re proud to contribute to SBB driving innovation for more durable and sustainable transport.”

The project builds on a shared ambition between SBB and CompPair to lead the way in sustainable innovation within the rail sector. As part of this collaboration, CompPair’s HealTech™ technology will be integrated into the refit programme of the ICN train fleet beginning in 2025, through existing SBB suppliers. This strategic move ensures seamless adoption within the current maintenance ecosystem, while introducing a significant step forward in reducing operational costs and environmental impact.

The ICN cowcatchers to benefit from CompPair's solution

The cowcatcher of the ICN trains – exposed to frequent impacts and traditionally requiring regular replacement – has been selected as the first component to benefit from CompPair’s solution. By replacing standard composite parts with repairable ones, maintenance teams will be able to heal damage directly on the part, reducing downtime and avoiding costly replacements. This not only improves operational efficiency but also supports SBB’s long-term sustainability goals.

“With this collaboration, we are taking a concrete step toward reducing material waste and maintenance costs while increasing the service life of key components,” said Pascal Vock, Head of Research and Innovation at SBB. “CompPair’s solution offers an exciting opportunity to combine operational efficiency with responsible resource management.”

By enabling longer lifetimes for train components and significantly reducing the frequency and cost of repairs, SBB is positioning itself at the forefront of a more durable and environmentally responsible rail industry. This partnership marks a key milestone in proving the business case for next-generation repairable composites, with future opportunities for broader implementation across the entire fleet.

Increasing adoption of HealTech composites across industries

Commercially, CompPair is experiencing strong momentum, with increasing adoption of its HealTech™ composites across industries such as sports, mobility, and aerospace. The startup has secured key partnerships with SBB, the European Space Agency on multiple projects, and Airbus Defence and Space on satellite applications. Successful client pilots are now paving the way for large-scale industrial integration, positioning the company for significant market growth. This September, CompPair will further expand its reach by launching a new product in the luxury sector during New York Climate Week.
