In January 2022, Industry Standards and Coordination Committee (ISCC) endorsed the establishment of a Data, Systems and Telematics Standards Committee (DST SC). This decision was subsequently approved at the RSSB Board meeting in March 2022.

The DST SC will be the first new Standards Committee to be set up for more than a decade. The Committee will have responsibility for managing the change control process for the Telematic Applications for Freight and Passenger Services (TAF & TAP) National Technical Specification Notices (NTSNs) and will oversee the development and maintenance of standards, guidance notes and other documents that support transport operators in sharing data more easily and exploiting it more effectively.

RSSB is in the process of establishing the Committee in accordance with the Standards Code and Standards Manual. The aim is for the first meeting to take place in early summer 2022.


The scope of the DST SC is defined in its draft remit. The Committee’s coverage includes:

  • Systems that assist in long-, short- and very-short-term planning of the railway, across timetabling, rolling stock and traincrew, as well as the reference databases that support these functions. This also includes the provision of live operational information, such as train running, location, and allocation information.
  • Data that support the processes and systems above and would usefully be shared between organisations through open, standardised interfaces. This may include the creation of standardised data models.
  • The technical requirements set out in the TAF & TAP NTSNs for the exchange of data, information, and messages between organisations and systems.


DST SC members will be sought from these industry stakeholders:

  • passenger train operators
  • rolling stock owners and leasing companies
  • freight and other non-passenger train operators
  • infrastructure managers and owners
  • infrastructure contractors
  • suppliers and rolling stock manufacturers
  • RSSB
  • Department for Transport (observer)
  • Office of Rail and Road (observer).
