Radar-Derived Rainfall 

High-resolution rainfall data that keeps your network moving.

EWN’s Radar-Derived Rainfall (RDR) service transforms national radar coverage into precise, real-time rainfall intelligence for rail networks.

A challenge for remote rail corridors is knowing exactly when and where rain is falling across vast and often remote locations

By combining live radar data with recorded rainfall measurements, RDR fills the gaps left by traditional ground gauges, giving operators visibility across vast and remote corridors that would otherwise remain unmonitored.

With hyperlocal rainfall alerts mapped directly to your rail assets, operators gain the foresight to anticipate flooding, protect crews, and maintain safer, more reliable services during severe weather.

  • Network-wide coverage allows monitoring of rainfall across the entire Australian rail network, including remote corridors without physical gauges.

  • Advanced modelling integrates radar and gauge data to deliver accurate estimates where no sensors exist.

  • Receive hyperlocal, asset-level rainfall intelligence for track sections, bridges, and culverts.

  • Real-time SMS and alerting send automated notifications to empower operators to act swiftly, minimising risk to crews and infrastructure.

Accurate, real-time data for rainfall is essential for safe and reliable rail

Why RDR is Important For Rail

 

Heavy rainfall is one of the leading causes of flash flooding, washouts, and track damage across Australia’s rail corridors. Without dense ground monitoring, critical rainfall can go undetected until it’s too late.

By closing those gaps with radar-derived rainfall intelligence, operators gain complete visibility, real-time awareness, and the confidence to act early — reducing disruption, protecting assets, and keeping crews safe.
