Railway

Drive testing, verification, and EN 50128 certification of railway software and systems to ensure reliable and secure rail operations.

With over two decades of industry expertise, our company provides comprehensive verification and validation services tailored to the rigorous demands of the rail sector. We specialize in ensuring full compliance with essential CENELEC standards, bringing a deep understanding of safety-critical processes to every project. Our extensive track record spans more than 20 years, during which we have successfully handled a diverse range of systems across all safety integrity and criticality levels. From complex On-Board Units to mission-critical trackside infrastructure, we deliver meticulous verification at every stage, including both software and full-system levels. By combining long-standing experience with a precise methodical approach, we help our partners navigate regulatory complexities and guarantee the highest standards of operational safety and reliability for modern rail networks.

Competences
CENELEC Compliance & Safety Management

CENELEC Compliance & Safety Management

We ensure uncompromising adherence to EN 50126, EN 50128, and EN 50129 standards. Our expertise covers the entire safety lifecycle, from initial risk assessment to the final Safety Case, ensuring that every system meets the highest regulatory requirements for functional safety and certification.

Full-Stack Verification & Validation

Full-Stack Verification & Validation

Our team provides comprehensive V&V services across the entire V-model. By integrating rigorous testing at both software and system levels, we guarantee that complex rail applications perform exactly as specified, identifying potential issues early to ensure a seamless transition to operation.

On-Board & Trackside Solutions

On-Board & Trackside Solutions

We possess deep technical knowledge of both mobile and stationary rail infrastructure. From sophisticated On-Board Units (OBU) to critical trackside systems, we verify the vital communication interfaces and control logic that keep trains and infrastructure synchronized and safe at all times.

Multi-Level Criticality Expertise

Multi-Level Criticality Expertise

With extensive experience across all Safety Integrity Levels (SIL), we handle projects of every complexity. Whether managing SIL 4 mission-critical systems or lower-criticality monitoring tools, we apply the precise level of rigor required to balance safety, efficiency, and cost-effectiveness.

Requirement Engineering & Traceability

Requirement Engineering & Traceability

Precision begins with the first specification. We establish robust requirement management processes that ensure full traceability throughout the project lifecycle. This systematic approach provides the necessary documentation and clarity required for successful audits and regulatory approvals.

Legacy Systems & Modernization

Legacy Systems & Modernization

Leveraging over 20 years of industry experience, we specialize in the validation of legacy systems and complex retrofitting projects. We help operators modernize their existing fleets and infrastructure by bridging the gap between historical technology and modern safety requirements.
