Rail asset health platform

The problem

Faults on rail assets were logged in an ageing in-house application. Fault reports were duplicated and inconsistent, and there was no single register of rolling stock and wayside assets.

What we did

• Owned the solution architecture with the client's rail subject matter experts, from problem definition and design through build, validation and handover.
• Built data pipelines that bring in alarm and fault data from the control systems, a standardised fault log, and a central asset register covering rolling stock and wayside assets.
• Delivered applications on top of the data for the workshops, including out-of-service dashboards, asset status management, live train control data and collaboration tools.
• Mentored the client's developers on the platform through pairing, code reviews and knowledge transfer.

The result

• Alarm data now reaches the platform within seconds, down from more than 10 minutes, after working with several teams across the business.
• One source of truth for asset health, with less manual data entry, more consistent data and faster fault recovery.
• A foundation built for reliability analytics and AI-assisted fault diagnosis, with AI features now in development.
