TÜV Rheinland holds NoBo, DeBo, and AsBo qualifications across multiple European countries. Projects that require more than one type of assessment – which is common – can be managed within a single engagement. This reduces coordination effort, eliminates handover risk between providers, and keeps your authorization process on a single timeline.

As a designated third party, TÜV Rheinland operates independently from manufacturers, operators, and project owners. Our conformity assessments are impartial and independent by regulatory definition – and by professional practice. This independence and professional expertise are what provides trust in our certificates, reports, and conformity documents. TÜV Rheinland third-party conformity assessment bodies are members of NB-Rail and fully supports third-party concept and commits to a Single European Railway Area conceived and built to a set of European requirements without any technical barriers.

Regulatory gaps identified late in a project are costly. TÜV Rheinland accompanies projects from the concept phase – helping teams identify which conformity assessments apply and avoid compliance issues before they affect timelines or budgets. Early involvement supports smoother authorization, not just assessment at the end.

With rail specialists across Europe and beyond, TÜV Rheinland combines international project experience with in-depth knowledge of international and national regulatory framework. Whether your project targets a single country or spans multiple networks, we bring the right regulatory expertise to each market – without the need for multiple local providers.

Clear deliverables, defined milestones, and direct access to your conformity assessment team give you budget certainty and stakeholder confidence throughout the process. Our teams respond quickly to technical questions and keep documentation structured and accessible – so authorization dossiers are ready when authorities require them.
