Rolling Stock – Freight Wagons Technical Specification for Interoperability - National Technical Specification Notice Mirror Group
04/05/2022
The Rolling Stock – Freight Wagons Technical Specification for Interoperability/National Technical Specification Notice Mirror Group (WAG TSI/NTSN MG) is a subgroup of the Rolling Stock Standards Committee (RST SC). It shares, coordinates and collectively agrees GB views on matters relevant to changes to National Technical Specification Notices (NTSNs) and Technical Specifications for Interoperability (TSIs).
"The WAG TSI/NTSN MG was established when RST SC decided to delegate responsibility for monitoring the WAG TSI and considering the resultant changes required in the WAG NTSN. Rail freight has been identified as a key enabler to support Great Britain’s decarbonisation goals, and the WAG NTSN is the foundation on which standards for freight wagons rest. It’s therefore of vital importance that this both incorporates best practice and provides the flexibility that the rail freight industry needs to be able to continue to serve its customers efficiently and effectively, and the role of this group is to ensure this is the case."
Scope
The functions and responsibilities of NOI 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 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 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 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 WAG TSI/NTSN MG consults with other TSI/NTSN mirror groups, predominantly the LOC/PAS TSI/NTSN MG and NOI TSI/NTSN MG, and other industry groups on related interface matters to ensure consistency between subsystems.
