Project Overview.
Tomaers Consultancy provided tunnel ventilation and fire life safety engineering for HS2, the United Kingdom's transformative high-speed rail link connecting London, Birmingham, and the North. The project required advanced aerodynamic and thermodynamic modelling of tunnel ventilation systems, emergency evacuation analysis, and fire scenario simulations for some of Europe's longest bored tunnels. Our engineers developed performance-based fire strategies that satisfy both UK and European rail safety standards.
