Resilient rail  infrastructure 
for a changing climate

Wireless sensors, the key to protecting your railway assets from increasingly-frequent extreme weather events due to climate change

Extreme heat in central and southern Europe increased roughly tenfold between 1961and 1990 and between 2010 and 2024. Extreme heat events are now more frequent, longer, more intense, and more widespread than ever before. Rail infrastructure is particularly vulnerable to these extreme weather events. The ability to rapidly identify weather-related risks is crucial to keeping trains running safely and reliably amid more frequent and severe extreme weather events.

 Both extreme heat and extreme cold stress rails, overhead catenary lines, and, more broadly, metal trackside assets like substations and signaling equipment. As temperatures rise, rails can buckle due to heat—even in northern Europe. When the mercury drops, frost and ice on overhead catenary lines can cause catenaries to spark, interrupting the power supply. Pantographs can also be damaged or detached. In a changing climate, these thermal stresses are no longer seasonal nuisances—they are now structural maintenance challenges. Preventive maintenance—like proactively managing damage to rails and taking anti-icing measures—requires real-time insights and alerts.

In today’s changing climate, doing nothing is no longer an option—nor is relying on annual manual field inspections or weather alerts. Railway operators across the continent are already looking for reliable, scalable, easy-to-implement monitoring solutions to make data-driven decisions without making field technicians’ jobs more complicated. Moïz provides wireless, batteryless IoT sensors for railway asset monitoring, giving you the data you need to quickly identify all weather-related risks before they disrupt service or create safety hazards.
