Approval of rolling stock: controlled deadlines
A turnkey offer to manage the end of life of rolling stock, combining technical expertise, compliance with environmental standards and valorization of components. From on-site delivery to waste traceability, our teams take care of each stage of the process, ensuring the sustainable management of recyclable and dangerous materials.

Approval of Rolling Stock
The validation and certification of rolling stock is often an essential regulatory step for any railway (re) commissioning project. Faced with ever more complex European and national regulations, operators and manufacturers must demonstrate the conformity, safety and interoperability of their equipment.
The authorization process
Our teams perfectly master the authorization process and support you until you obtain the CE certificate for your rolling stock. In particular, this involves:
- Active regulatory monitoring to identify applicable texts and standards (STI, NRD, standards, laws, etc.)
- A precise analysis of the significance of the changes and their impact on the rail system
- Conducting MSC Risk Analyses and Defining a Coherent Admission Strategy
- The constitution of complete technical files: conformity matrices, design proofs, test plans, etc.
- The coordination of independent evaluators and the management of exchanges with the competent authorities (ERA, ANS, STRMTG)
