## Summary

FIRST GREATER WESTERN LIMITED, a private utility company, has recently completed a direct procurement process for the supply and maintenance of the Class 387 Driver Advisory System (DAS). Based in Wiltshire, United Kingdom, the buying organisation awarded the contract to TTG TECHNOLOGY (EUROPE) LIMITED, the only supplier capable of providing the necessary technical software. This contract, classified under the IT services industry category, will run from 30th March 2026 to 31st December 2029, with potential extension options. The procurement method was a direct award tailored to avoid technical and operational incompatibilities, incurring a contract value of £1,148,351.22 excluding VAT.

This opportunity represents significant potential for businesses specialising in IT services, particularly those focused on consulting, software development, and support for transport systems. The procurement process highlights the need for specialist suppliers who can meet stringent industry standards and timelines. Businesses capable of offering innovative solutions in real-time data management and train safety optimisation can leverage this type of contract to strengthen their portfolio and expand their footprint in the rail technology sector. As the contract includes options for additional hardware, there is scope for businesses dealing with complex rail system integrations to explore future collaborations with public utility entities.

## Notice

C-DAS takes data from Traffic Management (TM) systems and automatically sends changes in real-time to the DAS system onboard the train. TM systems have visibility of all train movements through a given area and apply predictive logic to the underlying data to recommend changes that will result in optimising the combined performance of all the trains.

### Procurement Information

Modification of contracts during their term (extension) The modification provides for the supply of goods and services in addition to the goods and services already provided for in the contract and using a different supplier would result in the supply of goods and services that are different from, or incompatible with, those already provided for in the contract. This difference or incompatibility would result in: (i) disproportionate technical difficulties in operation or maintenance or other significant inconvenience, and (ii) the substantial duplication of costs for the authority. The intention to extend the current contract for the supply of pre-installed Driver Advisory System (DAS) Software, Support and Maintenance as required on the Class 387 fleet is a pre-cursor to being able to meet our National Rail Contract commitment to implementing Connected DAS (C-DAS). Without this agreement in place, we will be unable to deliver these commitments across both the Class 387 fleet and Class 802 fleets. TTG Technology (Europe) Limited are the only supplier who can provide the technical aspects of this requirement as the only supplier who provide this specialist software, in accordance with industry timelines, standards across the entire GWR fleet and wider rail safety standards.
