References to EU legislation and institutions
From 1 January 2021 the EU Technical Specifications for Interoperability (TSIs) have ceased to apply in the UK. These have been replaced by National Technical Specification Notices (NTSNs) pursuant to regulation 3B of the Railways (Interoperability) Regulations 2011. The technical content of TSIs have been substantially reproduced in the NTSNs except where GB specific alternatives are identified as specific cases in the relevant NTSNs. Therefore references to TSIs correspond to equivalent references in NTSNs.
There may be some older documents in the Standards Catalogue that will still reference TSIs until they are updated. References to TSIs should be read as NTSN.
Additionally, any references to EU Directives, Regulations and Decisions that are no longer applicable in the UK should be read in conjunction with relevant UK regulations and associated guidance. The same applies to references to the European Commission (EC) or European Union Agency for Rail (ERA) as they do not play any role in discharging any functions or obligations under domestic regulations. Any technical documents and specifications published by relevant EU institutions remain valid references for use if also referenced by relevant UK regulations and associated documents.
All references to TSIs, EU Directives, Regulations and Decisions are subject to change when standards are next updated.
