This legislative order establishes the legal status of specific international railway tariff agreements within the framework of the European Communities Act 1972. The document is issued by the government of Great Britain to formally define these international agreements as 'Treaties' under UK law, thereby ensuring their domestic legal recognition and enforceability. It serves as a technical instrument to align national regulatory structures with international obligations regarding cross-border rail transport.

Legal professionals and parliamentary researchers utilize this document as a primary source for verifying the legislative history of UK-EU treaty integration. It is recognized as a standard administrative instrument rather than an analytical text, serving strictly as a record of legal status for regulatory compliance.
