Crosswind safety

Consulting service dedicated to crosswind risk analysis

We assess the crosswind risk on railway lines (high-speed line, conventional line, or elevated train) and define tailor-made wind protection solutions accordingly.

We characterize extreme winds along the track with a 50-meter resolution at train height using our CFD (Computational Fluid Dynamics) simulation software. The crosswind risk computation includes a statistical analysis of extreme events, the aerodynamic characteristics of the rolling stock, the local geometric data of the infrastructure (embankment height, cant, curve radii, etc.) and the risk criteria specific to the network operation.

The protective measures ensure the traffic safety and respond to the risks and operational constraints of each project (windbreak, DVL system (Lateral Wind Detector), weather forecasting tools for interrupting traffic).
