## Summary

Network Rail Infrastructure Limited is initiating a procurement process titled "SR41046 - Infrastructure Monitoring – Overhead Line Equipment on In-Service Vehicles (Dynamic OLE Data)", falling under the telecommunications-infrastructure maintenance services category. The project involves designing, building, and managing technologies to handle Overhead Line Equipment data efficiently, ensuring swift identification of potential issues to avert train disruptions. This procurement is planned to begin with a break clause opportunity at three years within a four-year framework. The procurement method used is a competitive flexible procedure, with a total estimated contract value of £22.452 million. Located in the UK, this initiative is currently at the planning stage, following the publication of a planned procurement notice on 13 April 2026, with further notices anticipated by 5 May 2026.

This tender presents significant opportunities for businesses specialising in telecommunications infrastructure maintenance, particularly those equipped to manage dynamic data processing and analysis systems for in-service vehicles. With the framework favouring a diverse supply chain, SMEs have the potential to compete effectively. The opportunity to contribute to frequent and real-time monitoring solutions for Network Rail could stimulate growth for businesses already engaged in transportation technology, big data analysis, and digital communication, helping them expand their market presence in the utilities sector.

## Notice

The procurement scope includes designing, building, operating, and maintaining specialised technologies for capturing, processing, analysing, storing, and transmitting Overhead Line equipment data, and translating it into immediately actionable information. Separate from the core fleet requirements, OLE monitoring has been identified as an area where it is most effective to gather data from in-service passenger trains, with successful trials having been undertaken. The primary benefit of this approach is the frequency of data collection, which can provide alerts for emerging defects, allowing a quick response to prevent de-wirements and the associated significant train service disruption. The term of the framework shall be 4 years (with a break clause at 3rd anniversary or thereafter) with no extensions. Contract term is four years with a break option after year three; forecast value is PS22.452m. Performance will be managed through a focused SLA/KPI set.
