Scope

The functions and responsibilities of LOC & PAS TSI/NTSN MG are to work with RSSB to make recommendations to RST SC with regards to:

  • proposals to change NTSNs and TSIs, including the implications of NTSN and TSI changes on national technical rules
  • comments on NTSNs and TSIs to be channelled to the GB sector representative to influence TSI development and RSSB as the organisation managing NTSN changes
  • whether to align or diverge NTSN requirements from TSI requirements, aligning with relevant strategies approved by the RST SC, wider sector strategies and government policy
  • the need to develop GB-specific cases in the NTSN and associated national technical rules, and make recommendations to the RST SC
  • NTSN changes drafted by RSSB and associated analysis developed by RSSB
  • interim or permanent solutions to address relevant NTSN challenges and issues and how to codify them in the NTSN issues log.

Where necessary and required, the LOC & PAS TSI/NTSN MG consults other TSI/NTSN mirror groups and other industry groups on related interface matters to ensure consistency between subsystems.

The group reports to the Rolling Stock Standards Committee.
