What Ertms Users Group does

EEIG ERTMS Users Group (EUG) is a European Economic Interest Grouping formed in 1995 and headquartered in Brussels, Belgium. Its mission is to coordinate the harmonized and interoperable deployment of ERTMS (European Rail Traffic Management System) across European railways by combining the technical knowledge and deployment experience of its members. EUG is not a commercial entity: it is member-owned and funded, operating through a lean 7-person secretariat with no external investors or commercial revenue model.

EUG's 13 members comprise essentially all major European railway infrastructure managers, including DB AG (Germany), SNCF Réseau (France), Network Rail (UK), RFI (Italy), ADIF (Spain), PRORAIL (Netherlands), INFRABEL (Belgium), SBB (Switzerland), Bane NOR (Norway), Banedanmark (Denmark), Trafikverket (Sweden), Správa železnic (Czech Republic), and the Finnish Transport Infrastructure Agency. Its portfolio spans core ETCS (European Train Control System) specifications, Automatic Train Operation (ATO) covering GoA1–GoA4, Hybrid Train Detection (HTD), the Target Architecture for CCS, ERTMS Security Guidelines, and Train Localisation Working Group deliverables on GNSS-augmented positioning.

EUG's go-to-market is standards coordination rather than product sales. It participates in the EU-Rail Joint Undertaking System Pillar alongside EULYNX, OCORA, and ERA, contributes to Technical Specifications for Interoperability (TSI) maintenance, and publishes technical specifications and guidelines made available through its website and to railway stakeholders. The organization does not commercialize products or operate a pricing model; its outputs are reference architectures, requirements documents, and security guidelines that shape European rail signalling procurement.

Core offering

ERTMS Users Group develops, maintains, and harmonises technical specifications, engineering guidelines, and test specifications for the European Rail Traffic Management System (ERTMS), encompassing ETCS, GSM-R/FRMCS, Hybrid Train Detection, Automatic Train Operation, the Target Architecture for CCS, train localisation, and cyber security. It acts as a non-commercial technical secretariat coordinating its 13 member railway infrastructure managers to support interoperable ERTMS deployment across Europe.

Product overview

The EEIG ERTMS Users Group is a European economic interest grouping formed in 1995 that develops and promotes ERTMS (European Rail Traffic Management System), a unified railway control and communication system. ERTMS consists of three main components: ETCS (European Train Control System) for automatic train protection, GSM-R/FRMCS radio-based communication, and ETML (European Traffic Management Layer) for train location information. The group's activities focus on ETCS and related radio communication specifications. Their portfolio includes core ETCS specifications, Hybrid Train Detection (HTD) for capacity optimization, Automatic Train Operation (ATO) across all automation grades, Target Architecture for CCS, Security Guidelines, and Localisation Working Group deliverables. These products work together to enable safe, reliable, and interoperable railway operations across Europe.

Partnerships

Ten partnerships are on record, tiered core and supporting.

• EULYNXcoreStrategic or Co-development Partner · 1 January 2018Joint initiative starting 2018 for Reference CCS Architecture (RCA). EULYNX focuses on Trackside Assets Control & Supervision while EUG contributes CCS specifications. Together with OCORA (Open CCS Onboard Reference Architecture), these initiatives feed into the EU-Rail System Pillar.
• OCORA (Open CCS Onboard Reference Architecture)coreStrategic or Co-development Partner · 1 January 2018OCORA develops Open CCS Onboard Reference Architecture, parallel to EULYNX's trackside focus. Both initiatives joined the EU-Rail System Pillar in 2018 to develop future CCS specifications.

Scale indicators2 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• International Union of Railways (UIC): Global rail industry association that coordinates international rail standards and shares input with EUG on train localisation; broader geographic remit but directly comparable as a railway standardization body.
• OCORA (Open CCS Onboard Reference Architecture): Initiative developing open onboard CCS reference architecture; parallel to EUG/EULYNX's trackside work and co-participant in the EU-Rail System Pillar, sharing the same members and coordination model.
• EULYNX: European consortium of infrastructure managers developing standardized interfaces for trackside CCS assets; joint partner with EUG on the Reference CCS Architecture (RCA) and a direct parallel in mandate and structure.

Broad incumbents

• Hitachi Rail: Major supplier of ETCS and ERTMS-compatible signaling systems globally; operates in the same technology space as EUG but as a commercial implementer rather than a standards coordinator.
• Alstom: Major rail signaling and rolling stock vendor implementing ERTMS/ETCS specifications developed under EUG coordination; comparable as a stakeholder in the same ecosystem but commercially focused where EUG is standards-focused.
• Siemens Mobility: Global rail signaling and infrastructure vendor whose Trainguard ETCS products implement EUG specifications; comparable as a large incumbent in the same technology domain but commercially oriented.

Others

• European Union Agency for Railways (ERA): EU regulatory agency responsible for railway interoperability and author of TSIs; works closely with EUG as a regulatory counterpart rather than a direct competitor, issuing the standards EUG helps develop.
• European Rail Infrastructure Managers (EIM): Association representing European rail infrastructure managers; EUG participates as technical advisor to EIM, serving the same constituency from a different angle (advocacy vs technical coordination).
• Europe's Rail Joint Undertaking (EU-Rail JU): Public-private partnership funding and coordinating European rail research and innovation; the System Pillar that EUG coordinates sits within EU-Rail JU, making it a structural counterparty rather than competitor.
• Community of European Railway and Infrastructure Companies (CER): Brussels-based rail industry association representing operators and infrastructure companies; EUG acts as technical advisor to CER, an adjacent policy-level counterpart.
