Major rail technology company driving Europe's next-generation signalling, train automation, and digital railway architecture through the Shift2Rail programme.
Siemens Mobility is a major rail technology company that develops advanced signalling, train control, and automation systems for European railways. Within H2020, they focus on next-generation train communication (ETCS, CBTC), moving block signalling, automatic train operation (ATO), and cybersecurity for rail infrastructure. They also contribute to rolling stock innovation including SiC traction systems, HVAC, and smart maintenance technologies. Their work spans from core R&D on safety-critical rail systems to building demonstrators and prototypes for deployment-ready solutions.
Core contributor across the X2Rail series (X2Rail-1 through X2Rail-5), driving moving block, adaptable communication, and ATO development from concept to prototype.
Consistent thread from X2Rail-1 (ATO concept) through X2Rail-4 and TAURO (autonomous rail operation with environment perception and remote driving).
Contributed to LINX4RAIL and LINX4RAIL2 on system-of-systems architecture, conceptual data models, and digital twin governance, plus DIT4TraM on distributed intelligence.
Major funding in PINTA2 (EUR 1.4M) and PINTA3 (EUR 1.4M) for SiC traction development, high-speed train motors, and noise reduction; coordinated PIVOT2 (EUR 2.7M) on vehicle performance.
Cybersecurity features in X2Rail-3 and X2Rail-5; formal methods for safety-critical systems in X2Rail-2 and X2Rail-5.
Participated in IN2SMART, IN2SMART2, and IMPACT-2, covering intelligent asset management, decision support systems, and predictive maintenance.
In their early H2020 period (2016–2018), Siemens Mobility focused heavily on foundational signalling research — control systems, IP communication, ETCS/CBTC protocols, and initial moving block concepts through the X2Rail-1 and X2Rail-2 projects. From 2019 onward, their work shifted decisively toward system integration, standardisation, and deployment-readiness: digital twins, system-of-systems architecture, ontologies, and building physical demonstrators and prototypes. The trajectory shows a clear move from defining individual technologies to orchestrating them into interoperable, certifiable railway systems.
Siemens Mobility is moving toward full autonomous rail operation and interoperable digital railway architectures, making them a key partner for projects targeting deployment-ready, standards-compliant rail automation.
Siemens Mobility overwhelmingly operates as a participant (20 of 22 projects) rather than a coordinator, which reflects the role of a large industrial partner contributing deep technical capability to consortium-driven research. With 149 unique partners across 20 countries, they maintain an exceptionally broad network but are concentrated within the Shift2Rail ecosystem. Their consistent presence across sequential project phases (X2Rail 1–5, PINTA 2–3, IN2SMART 1–2) indicates they are a reliable long-term partner who stays committed through multi-year research agendas.
With 149 unique consortium partners across 20 countries, Siemens Mobility is deeply embedded in the European rail research ecosystem, particularly within the Shift2Rail Joint Undertaking. Their network spans most EU member states with strong ties to the major European rail industry and research actors.
As a global rail OEM, Siemens Mobility brings an unmatched combination of signalling, automation, and rolling stock expertise to H2020 consortia — few organizations can contribute across the full railway technology stack. Their sustained involvement across the complete X2Rail series means they carry deep institutional knowledge of Europe's next-generation signalling roadmap. For consortium builders, they offer both the engineering depth to deliver technical work packages and the industrial weight to ensure research results reach deployment.
