Interoperability and Standards
Interoperability is a European initiative aimed at improving the competitive position of the rail sector so that it can compete effectively with other transport modes, and in particular with road transport.
The Government expects interoperability to benefit the UK by
- Delivering economies of scale in the cost of components and equipment through the single market;
- Providing a consistent and simple pan-European approvals system for putting railway assets into service; and
- Reducing, to the extent that it will be possible for the UK, the barriers to the through operation of trains throughout Europe.
These webpages contain general information and generic advice about interoperability and its implementation in the UK, for the benefit of the rail industry and anyone with an interest in the development of rail transport in the UK. While we try to provide correct information here, we ask you to recognise that it is too condensed to be regarded as the legal authority on interoperability.
Listed below are the pages in the Interoperability site including an outline of their contents:

Common technical standards
Technical Specifications for Interoperability (TSIs), which apply to all European Member States, are being prepared progressively by the European Railway Agency. These are supplemented as necessary by UK-specific Notified National Technical Rules (NNTRs).
Subsystem authorisation process
Very brief outline of the obligations on the Contracting Entity, the requirement for authorisation and the process for obtaining it.
Registers and databases
Collection and management of information will be key to the achievement of interoperability. Outline of the key requirements on owners, keepers and operators of authorised infrastructure and rolling stock.

UK implementation and progress
How, and how quickly, is interoperability being rolled out in the UK (including links to UK implementation plans).
The basic principles of interoperability
The Regulations implement the two principal elements of the rail interoperability process, as defined in the Directives.

Future developments
The next 2 - 3 years are likely to see the transposition of a new Interoperability Directive - replacing the existing 3 Directives - into UK law, which will extend the scope of interoperability beyond the TEN, and introduce various features aimed at making the system more responsive to the needs of the rail industry.
