TSI Certification for Trans-European Rail Systems

What TSI certification covers

The TSI certificate confirms that equipment and systems used on Trans-European rail networks meet the Technical Specifications for Interoperability (TSI). The scheme regulates rail transport and brings a consistent set of technical requirements into force across participating European countries.

For manufacturers of rail equipment, TSI certification confirms conformity to the interoperability requirements and supports free movement of products and systems across European networks.

How TSI certification is obtained

The process runs in three stages, coordinated by Sistem Patent Kalite:

• Application: the file is prepared and submitted through Sistem Patent Kalite. We review the product or system dossier and confirm the applicable TSI requirements.
• Product or system evaluation: the product or system is assessed against the relevant TSI specifications, and any required testing and inspection are carried out.
• Certification and approval: once conformity is demonstrated, the TSI certificate is issued, and the product or system is cleared for free movement within the European rail network.

Which products and systems fall under TSI

TSI covers rail equipment and systems, including locomotives, wagons, rails, signalling, passenger transport systems, and related rail infrastructure. Our consultants review your product or system and confirm which TSI specifications apply.

TSI certification fees

Fees depend on product or system type, complexity, and the testing profile required under the applicable TSI. Contact Sistem Patent Kalite for a written quote for your specific case.
