Passenger equipment maintenance

An experience that makes a difference


You need to minimise the downtime of your urban or high-speed rolling stock and ensure optimum performance of trains and their equipment for passengers. Thanks to our experience in maintenance acquired on numerous railway rolling stock, our mastery of the different functions of the ECE (ECM railway) and a perfect understanding of the operators' constraints, we can guarantee our customers the best conditions of comfort, reliability and safety for their fleet.

A la carte service

As your operating constraints are specific, we intervene for one-off or recurring needs, for preventive or corrective maintenance operations. You thus benefit from tailor-made solutions that adapt to your requirements and your budget.

Continuous Improvement

In addition to our experience, ranging from urban to high-speed equipment, we rely on our engineering teams and the latest technological innovations to improve the safety, reliability and availability of your rolling stock.
