This article, co-authored by Russell Hargrave, Technical Advisor at RS Clare & Co Ltd, explores how advances in intelligent wheel-rail conditioning are transforming the way rail networks manage friction, wear and noise.

While traditional systems have relied on either trackside or onboard applicators, often working in isolation, new technologies are enabling smarter, more integrated approaches. Onboard systems in particular have evolved significantly, with more accurate application techniques and programmable controls using GPS, RFID and PIS data.

However, the article argues that these systems are not truly “intelligent,” as they rely on pre-set triggers. The next step is real-time monitoring of noise and vibration, supported by cloud connectivity, AI and machine learning. This would allow for condition-based application, network-wide optimisation and vehicles that share data to improve system performance.

It highlights how this shift could lead to a fully integrated friction management network, improving safety, reducing maintenance, and delivering long-term cost and environmental benefits.
