Cutting delays through data-driven maintenance

As one of the busiest and most operationally critical rail corridors in the United Kingdom, the Paddington route experienced increasing infrastructure-related issues that were impacting reliability, performance, and operational costs. As part of Project Brunel, Network Rail sought a digital solution to improve fault response times, enhance data availability, and reduce service disruption without altering the existing safety-critical axle counting system. 

To meet these objectives, Network Rail partnered with Frauscher UK & IE team to deploy Frauscher Insights Diagnostics, a secure, cloud-based monitoring solution that extends the diagnostic capabilities of the Frauscher Advanced Counter FAdC®. The solution was trialled from August 2023 at London Paddington station before being rolled out across twelve locations along the 13-mile section between Paddington and West Drayton, covering more than 750 wheel sensors installed across multiple relocatable equipment buildings. 

Frauscher Insights Diagnostics provides real-time fault notifications, detailed error descriptions, recommended corrective actions, and precise asset location data through a single intuitive interface. Instant alerts ensure maintenance teams are informed without delay, while health and pre-fault monitoring identifies emerging issues before they escalate into failures. Throughout the trial period, user feedback was incorporated into platform enhancements, and close collaboration with Network Rail’s cybersecurity teams enabled nationwide approval and full product acceptance in December 2024. 

By enabling faster fault analysis, improved asset awareness, and proactive maintenance, Frauscher Insights Diagnostics has significantly reduced downtime and delay minutes on the Paddington route by up to 80% for major fault events. The solution has also improved collaboration across more than 60 users and supported a shift from reactive fault response to data-driven maintenance, delivering measurable reliability improvements on one of the UK’s most demanding mainline routes.
