| Regulation | Council Decision (EU) 2026/1303, of 4 June 2026 |
|---|---|
| Publication | 10 June 2026 |
| Entry into force | Not specified |
| Affected parties | Railway companies, rolling stock manufacturers and railway certification authorities |
| Category | European Regulation |
| Organization | OTIF — Intergovernmental Organization for International Railway Transport |
| Reference session | 18th session of the OTIF Technical Experts Committee (TEC) |
Railway companies operating on international routes and rolling stock manufacturers face a significant technical update: the European Union has adopted, through Council Decision (EU) 2026/1303, its official position at the 18th session of the Technical Experts Committee (TEC) of OTIF, the body that governs international railway transport.
The practical result is revisions to uniform technical prescriptions that directly affect the homologation and certification of railway material. Those who fail to adapt their processes to the new standards may face obstacles to operating on international routes.
What does this regulation establish?
The Council Decision defines the position that the EU will defend at the 18th session of the OTIF TEC. The topics on the table are five specific technical blocks:
| Block | Content |
|---|---|
| TEC internal regulations | Review of the internal regulations of the OTIF Technical Experts Committee itself |
| UTP — Freight wagons | Review of uniform technical prescriptions applicable to the subsystem "rolling stock — freight wagons" |
| UTP — Locomotives and passenger stock | Review of uniform technical prescriptions applicable to the subsystem "rolling stock — locomotives and passenger rolling stock" |
| Uniform certificate format | Adoption of a uniform format for railway technical certificates |
| TAF — Telematics for freight | Review of the uniform technical prescription applicable to the subsystem "telematics applications for freight transport" |
The uniform technical prescriptions (UTP) are the international technical standards that railway subsystems (freight wagons, locomotives, passenger stock, telematics) must meet to operate on international routes under the COTIF convention. Their review means that current homologation certificates may become outdated with respect to new technical criteria.
The adoption of a uniform certificate format seeks to simplify and harmonize technical documentation among the different OTIF member countries, reducing administrative friction in the mutual recognition of homologations.
Economic and operational impact
This regulation does not establish direct economic sanctions or specific amounts in its text. However, its operational impact is significant on several fronts:
- Recertification of rolling stock: Freight wagons and locomotives operating on international routes will have to verify their compliance with the revised UTP. Depending on the scope of changes approved at the TEC session, an update or renewal of technical certificates may be required.
- Documentary adaptation: The adoption of a uniform certificate format requires updating existing technical documentation to align with the new standard.
- Telematics systems (TAF): Companies using telematics applications for freight transport management will have to review whether their systems comply with the revised uniform technical prescriptions for TAF.
- Homologation processes: Manufacturers of new rolling stock will have to incorporate the new requirements from the design stage, which may affect development timelines and costs.
Who does it affect?
- Railway companies operating international freight or passenger transport services under the COTIF/OTIF convention
- Rolling stock manufacturers: freight wagons, locomotives and passenger stock intended for international routes
- Railway certification authorities and notified bodies that issue or validate technical conformity certificates
- Railway logistics operators managing wagon fleets on European and Eurasian international corridors
- Technical and regulatory compliance departments of railway groups with cross-border activities
Practical example
A Spanish railway company operating freight wagons on the railway corridor to Germany or Poland under the OTIF regime must review whether its wagons comply with the revised UTP for the subsystem "rolling stock — freight wagons". If the new standards approved at the 18th TEC session introduce additional technical requirements (for example, in brakes, coupling or safety systems), the company will have to submit those wagons to a conformity verification process before the corresponding certification body and update its technical certificates to the new uniform format adopted. Similarly, if it uses telematics applications for tracking its wagons (TAF), it must verify that its system complies with the revised uniform technical prescription in that area.
What should companies do now?
- Identify affected rolling stock: Review which freight wagons, locomotives and passenger stock the company operates on international routes under the OTIF convention.
- Follow the results of the 18th TEC session: Monitor the resolutions adopted at the OTIF Technical Experts Committee session to understand the exact scope of changes to the UTP.
- Audit current technical certificates: Verify whether current homologation certificates for rolling stock will remain valid under the new uniform technical prescriptions.
- Review TAF systems: Verify that telematics applications for freight transport comply with the revised uniform technical prescription.
- Update documentation to the new uniform certificate format: Prepare the documentary transition to the standard format adopted by OTIF.
- Coordinate with the certification body: Contact the competent railway certification authority to plan the conformity verification processes that may be necessary.
Frequently asked questions
What are OTIF uniform technical prescriptions (UTP) and why do they change?
UTP are the international technical standards that railway subsystems (freight wagons, locomotives, passenger stock, telematics) must meet to operate on international routes under the COTIF convention. They are reviewed periodically at the OTIF Technical Experts Committee to adapt them to the technological and operational evolution of the sector. The 18th TEC session addresses the review of UTP for freight wagons, locomotives and passenger stock, as well as TAF telematics standards.
What is the uniform certificate format that OTIF adopts?
It is a standardized model of railway technical certificate that all OTIF member countries must use to certify the conformity of rolling stock with uniform technical prescriptions. Its adoption seeks to harmonize technical documentation and facilitate mutual recognition of homologations between countries, reducing administrative barriers in international railway transport.
When does this regulation enter into force and when must companies adapt?
Council Decision (EU) 2026/1303 was published on 10 June 2026 and does not specify a specific entry into force date. Adaptation timelines will depend on the resolutions adopted at the 18th OTIF TEC session. It is recommended to closely follow OTIF and European Union Agency for Railways (ERA) publications to learn about applicable transition periods.
Does this regulation affect only freight transport or also passenger transport?
It affects both. The review of UTP includes both the subsystem "rolling stock — freight wagons" and the subsystem "rolling stock — locomotives and passenger rolling stock". Additionally, TAF telematics prescriptions are reviewed, which are specific to freight transport.
What is OTIF and what is its relationship with EU railway regulations?
OTIF (Intergovernmental Organization for International Railway Transport) is the international body that manages the COTIF convention, the legal framework for international railway transport. The EU is a member of OTIF and, through Council decisions such as 2026/1303, sets the official position that its representatives defend in OTIF technical committees, ensuring consistency between European railway regulations and international standards.
