Network Rail is procuring services to monitor overhead line equipment from in-service passenger trains. The £25 million opportunity covers roof-mounted pantograph and OLE monitoring systems, forward-facing video and analytics, secure data provision, installation, operation and ongoing maintenance.
This is not a conventional framework. Network Rail intends to award multiple parallel contracts across two lots and then commission fleet deployments incrementally through in-contract requests for quotation. If your organisation is considering the participation stage, speak to Thornton & Lowe about your rail technology submission.
What are the two lots?
The procurement is divided into:
- Lot 1: Roof-Mounted Pantograph and OLE Monitoring, valued at an estimated £16 million excluding VAT.
- Lot 2: Forward-Facing Video OLE Monitoring, valued at an estimated £9 million excluding VAT.
Lot 1 covers instrumented pantographs, roof-mounted video or measurement equipment and related analytics. Lot 2 covers forward-facing video systems and the analytics needed to identify developing OLE defects.
The Network Rail tender notice lists several fleets and routes under consideration, including ScotRail, West Midlands, London Overground, Northern, GTR and East Midlands Railway services.
Who should consider participating?
The strongest candidates are likely to be suppliers or consortia that combine several capabilities:
- proven railway sensing or inspection technology;
- rolling-stock design, installation and integration;
- video analytics, machine vision or condition monitoring;
- secure data capture, transmission, storage and processing;
- software and user interfaces for actionable alerts;
- maintenance, calibration and lifecycle support;
- delivery within railway safety, assurance and cyber requirements.
Network Rail is open to different data-collection methods and encourages innovation, but the proposed solution must be demonstrably proven. Early-stage concepts without operational evidence are unlikely to meet the requirement.
Suppliers new to the buyer can use our guide to Network Rail frameworks and opportunities to understand the breadth of goods and services Network Rail procures, the routes available to SMEs and the value of planning for upcoming competitions.
How will suppliers be selected?
The procurement uses a competitive flexible procedure. At the participation stage, suppliers must complete a Procurement Specific Questionnaire covering financial standing, technical capability and relevant experience.
Network Rail expects to shortlist up to five suppliers per lot. A sixth may be included where its score is within 2% of the fifth-ranked supplier. Shortlisted organisations will then receive a single-stage invitation to tender, including an electronic auction, and up to three contracts may be awarded in each lot.
The tender-stage evaluation is weighted 60% to quality and 40% to cost. Quality themes include system performance, measurement capability, design and integration, data and cyber security, implementation, lifecycle support and social value.
What evidence will matter most?
Strong responses should show how the system moves from proven technology to dependable fleet deployment. Evidence should cover:
- accuracy, repeatability and validation of measurements or alerts;
- successful operation in comparable rail environments;
- fitment constraints, approvals and vehicle interfaces;
- data security, ownership, resilience and information management;
- maintenance, fault response and system availability;
- scalable deployment across different fleets and routes;
- clear responsibilities across consortium members and subcontractors;
- how outputs help Network Rail prevent failures and reduce disruption.
Technical claims should be supported by test results, trial outcomes and clearly defined performance measures. Network Rail needs evidence that the data can support timely operational decisions, not simply that the technology can collect information.
Prepare for both stages
The participation deadline is 10 August 2026 at noon. The invitation to tender is currently expected in late September, although that date may change.
Suppliers should use the first stage to establish a credible team and prove relevant experience, while preparing the commercial and technical detail needed for the tender and eAuction. Consortium agreements, data responsibilities and rolling-stock partners should be resolved early, because unclear delivery ownership could weaken both the qualification response and the later tender.
