The procurement process involves early market engagement to refine the project's specifications and does not bind TfL or suppliers to any commitments at this phase. The engagement includes preliminary notices, interactive supplier sessions, and a supplier day, with interested parties invited to submit their responses by 1 August 2025. The procurement is categorized under services with a special regime for utilities and covers industry-specific software packages related to railway transport services. The contract period is set to start in March 2026, concluding in March 2029, with procurement carrying out in the UK region, specifically at TfL’s headquarters in London. This tender presents significant growth opportunities for businesses specializing in custom software development, railway transport support services, and those offering programming services of packaged software products. Companies with advanced technological capabilities in weather data processing and railway system integration are well-positioned to compete, particularly small and medium enterprises (SMEs). Through innovation, suppliers can contribute to developing a custom adhesion prediction tool, addressing rail adhesion challenges and enhancing passenger transport efficiency in urban environments. By participating, businesses can influence the specification of the project and potentially secure long-term partnerships with TfL. ## Notice This notice is issued by TfL to notify the market of our intention to carry out market engagement and a potential future tender which may commence in March 2026. The total contract value is unknown at this time we are embark on this market engagement process. This process does not commit TfL or potential suppliers to any spend. The specification has yet to be developed, however the findings from this market engagement process will inform the final specification. Scope: To transport the high number of passengers required in a modern city constrained by legacy tunnels and platform lengths needs more frequent trains which in turn requires higher acceleration and brake rates. However, to prevent wheel spin under acceleration or wheel slide under braking requires a minimum level of adhesion (friction) at the wheel rail interface. Adhesion Controllers Condition Assessment Tool (ACCAT) has been employed over the last 20+ years on the Central line and approaching 6 years on the Sub Surface Railway. Using the underlying logic, the ACCAT processes weather data provided by a 3rd party and several other inputs to predict the available rail adhesion and outputs recommendations in the following three categories: 1. The operation of railhead treatment trains, thus improving the level of adhesion available to trains. 2. Brake rate reduction, thus reducing the adhesion required to stop the train. It also recommends when an imposed brake rate reduction can be removed 3. Severe weather warnings TfL is interested in the innovation software development solutions offered by the market for the development of a custom adhesion prediction tool. ### Planning Information This exercise does not form part of any formal procurement process. All responses will be carefully considered but will not bind TfL to any approach to the procurement, nor will responses be treated as conveying any promise or commitment on the part of the respondent.
