The Standards and Regulation Group (SRG) steers UNIFE’s technical activities in the fields of the European regulatory framework namely: the Interoperability Directive, Safety Directive, and other directives applicable to the European railway system

The SRG is organised so that it provides both overall coordination and steering of the UNIFE’s technical activities concerning the European Technical Regulatory framework (including overseeing the UNIFE Topical and Mirror Groups) and also the interface with other internal UNIFE activities and external organisations.

The SRG interfaces mainly with the following UNIFE Committees:

  • UNIRAILINFRA (civil works and infrastructure interfaces), in particular Energy and Infrastructure subsystems;
  • UNISIG (Control-command interfaces with Rolling Stock and Infrastructure Sub-systems), in particular CCS on board and track-side subsystems;
  • UNIFE Sustainable Transport Committee (STC);
  • ERWA – UNIFE Railway Wheels and Wheelsets Committee
  • UNIFE Technical Plenary


This figure illustrates the SRG's internal structure and interfaces

The SRG also interfaces with the following external organisations/bodies:

  • European Institutions drafting and railway regulations including the European Commission and European Railway Agency
  • European Standardisation Bodies including CEN, and CENELEC via the Joint Programming Committee for Rail (JPCR)
  • Other Rail Sector Associations including CER, EIM, UIC, UIP, UITP, UIRR, EPPTOLA and ERFA via the Group of Representative Bodies and ERA Network of Representative Bodies

The Group of Representative Bodies (GRB)
UNIFE is a member of the Group of Representative Bodies, a grouping of railway associations in Europe with the role of supporting, in a transverse way, the rail sector’s input to the European Railway Agency (ERA) work programme and its effect on safety and interoperability. Furthermore it plays a role in developing the activities associated with research, innovation and standardisation and therefore has links with European standardisation and research bodies and processes.

GRB is formed from the associations that are named as “Representative Bodies”, comprising the companies making up the railway operating community and the supply and manufacturing industry. Together these companies are responsible for the design, construction, operation and maintenance of the railway system.

The SRG coordinates the UNIFE input to the GRB, common positions and activities made by the GRB can be found at
