ADMINISTRADOR DE INFRAESTRUCTURAS FERROVIARIAS

Their core work

ADIF is Spain's national railway infrastructure manager, responsible for operating and maintaining the country's rail network including tracks, stations, and signalling systems. In H2020 projects, they serve as a real-world testbed and domain expert for railway innovation — from sensor-based monitoring and satellite-based signalling (ERTMS/Galileo) to hydrogen-powered trains and advanced traffic management platforms. Their participation brings operational railway expertise and access to live infrastructure that laboratory-only partners cannot provide.

What they specialise in

How they've shifted over time

In 2015-2018, ADIF focused on foundational railway infrastructure technology: fibre optic sensing, physical test environment virtualisation, and core rail system architecture (IN2RAIL, FINESSE, VITE). From 2019 onward, their focus shifted decisively toward digitalisation, decarbonisation, and intelligent operations — traffic management platforms (OPTIMA), hydrogen propulsion (FCH2RAIL), and high-accuracy digital mapping (RAILGAP). The trajectory shows a national infrastructure operator moving from hardware-level monitoring toward software-driven, green railway systems.

ADIF is moving toward green rail propulsion and digital traffic management, making them a strong partner for future projects on sustainable and intelligent railway operations.

How they like to work

ADIF exclusively participates as a partner rather than a coordinator, reflecting its role as an infrastructure provider and end-user rather than a research leader. With 186 unique consortium partners across 19 countries, they operate in large, diverse consortia typical of Shift2Rail and major transport innovation actions. This pattern signals an organization that contributes operational expertise and real-world validation environments rather than driving the research agenda — ideal for projects needing a major railway operator as a demonstration partner.

ADIF has built a broad European network of 186 partners across 19 countries, largely through large-scale transport and Shift2Rail consortia. Their network spans railway operators, signalling companies, research institutes, and sensor technology firms across Western and Southern Europe.

What sets them apart

As Spain's national rail infrastructure manager, ADIF offers something most research partners cannot: access to a live, large-scale railway network for testing and demonstration. Their participation across sensing, signalling, hydrogen propulsion, and traffic management means they can validate innovations across the full railway technology stack. For any consortium needing a major European rail operator as an end-user or demonstration site, ADIF is a proven and well-connected choice.

Highlights from their portfolio

• FCH2RAIL
  Represents ADIF's move into hydrogen rail propulsion — a fuel cell hybrid powerpack project signalling their commitment to rail decarbonisation.
• IN2RAIL
  Their largest single EC contribution (EUR 400,000) and a flagship Shift2Rail project for intelligent rail infrastructure innovation.
• OPTIMA
  A traffic management demonstrator combining integration layers, data models, and operator workstations — showcasing ADIF's role in digital rail operations.
