Infrastructure Monitoring – Overhead Line Equipment on In-Service Vehicles (Dynamic OLE Data)

Service Scope

Network Rail (NR) is issuing a Tender Notice for acquiring services related to Monitoring of the Overhead Line Equipment (OLE) in Great Britain.

The procurement scope includes designing, building, operating, and maintaining specialised sensor technologies for capturing, processing, storing, and transmitting output data. 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 dewirements and the associated significant train service disruption.

New Technology and Innovation

Network Rail is agnostic to the method of data collection, and is keen to promote new technology and innovation. For this dynamic OLE project, the solutions provided to meets the requirements must be a demonstrably proven solution.
