ARDANUY INGENIERIA SA

Their core work

Ardanuy Ingeniería is a Spanish railway engineering consultancy specializing in signalling, communication systems, and traffic management for rail transport. They contribute technical expertise in ERTMS/ETCS standards, formal methods for safety certification, and integration of communication platforms for railway operations. Their work spans from energy harvesting for trackside equipment to cybersecurity frameworks for the rail sector, positioning them as a versatile engineering partner within the Shift2Rail ecosystem.

What they specialise in

How they've shifted over time

Early projects (2016–2018) concentrated on core railway signalling infrastructure: ERTMS/ETCS standards, train integrity systems, trackside controllers, and radio communication — the fundamental building blocks of rail control. By 2019, the focus shifted toward higher-level system integration: traffic management platforms, operator workstations, application frameworks, and cybersecurity for railways. This progression suggests a move from component-level engineering toward system-of-systems integration and operational security.

Ardanuy is moving up the stack from signalling hardware toward integrated traffic management platforms and cybersecurity — making them increasingly relevant for digital rail transformation projects.

How they like to work

Ardanuy predominantly operates as a project participant (4 out of 5 projects), contributing specialist engineering expertise to larger consortia. They coordinated one project (4SECURAIL), their smallest by budget, suggesting they are comfortable leading focused, niche initiatives while joining bigger efforts as a technical contributor. With 26 unique partners across 10 countries, they maintain a broad European network rather than relying on a small circle of repeat collaborators.

Ardanuy has collaborated with 26 distinct partners across 10 European countries, reflecting strong integration into the Shift2Rail community and broader EU rail research ecosystem. Their network spans multiple rail-focused institutions and industrial partners across Europe.

What sets them apart

Ardanuy brings a rare combination of deep ERTMS/ETCS signalling expertise with growing capabilities in railway cybersecurity and traffic management integration — areas where engineering firms with hands-on rail experience are in short supply. As an SME, they offer more agility and specialist focus than large rail integrators, while their Shift2Rail track record demonstrates credibility within the European rail innovation programme. Their 4SECURAIL coordination shows they can lead on formal methods and CSIRT for railways, a niche few engineering firms occupy.

Highlights from their portfolio

• ASTRail
  Largest budget (EUR 339,562) — satellite-based signalling with formal methods, combining space technology with railway safety verification.
• 4SECURAIL
  Their only coordinated project, focused on cybersecurity (CSIRT) and formal methods for rail — signals a strategic push into railway security.
• OPTIMA
  Most recent and longest project (2019–2023), marking their shift toward integrated traffic management platforms and system-level demonstrators.
