Key insight

Weather stations controlling automatic point heating saved 3.2 GWh and approximately €500,000 in the coldest week of winter 2022–23 alone — demonstrating that real-time monitoring pays back rapidly in avoided emergency maintenance costs.

Transferability to UK: HighDirectly applicable to UK rail.

Belgium's national rail operator Infrabel implemented a suite of climate adaptation measures addressing both high and low temperature extremes: tension release devices prevent tracks buckling in summer heat and fracturing in winter cold; automated weather stations trigger point heating to prevent switch rails freezing; storm basins and embankment assessments address flooding risk.

  • Rail infrastructure faces significant challenges due to climate-related hazards, including rising temperatures and heavy rainfall. These events accelerate the deterioration and premature ageing of rail systems, leading to increased maintenance requirements, renewal works, and crisis management - all of which impose considerable financial burdens.
  • High temperatures can cause track deformation, such as bending and buckling, and disrupt electrical systems, including signalling and electric traction.
  • Critical infrastructure elements like tracks, bridges, earthworks, and hydraulic structures are particularly susceptible to damage from heavy rainfall.
  • To address these challenges, Infrabel, the owner and maintainer of the Belgian railway network, has implemented a range of climate adaptation measures designed to mitigate damage and enhance the resilience of their rail infrastructure.

Transferability to UK: High

Directly applicable to UK rail. Tension release devices and automated point heating are standard but under-deployed technologies. The weather station network feeding automatic controls is directly replicable on Network Rail's managed infrastructure.
