Who shapes FRMCS?

FRMCS is shaped by the interplay of railway organisations, standardisation bodies, authorities and industry. This directory shows their tasks and contributions — from operational requirements through technical specifications to regulatory requirements.

Editorial status: All entries are under review. The short descriptions rely on the linked official source in each case; the original source is always authoritative. A publication by a body is not automatically legally binding.
