Why Do Train Tracks Buckle in Extreme Heat?

What happens to railway tracks when temperatures become extreme? In this video, we explain the hidden engineering behind railway tracks and why extreme heat can cause steel rails to expand, develop huge compressive forces, and potentially buckle sideways. You'll discover how continuous welded rails work, why ballast and sleepers are important, how engineers control thermal stress, why trains may face speed restrictions during heatwaves, and how modern railways are adapting to rising temperatures. 🔥 Heat 🚆 Railway Engineering 🛠️ Track Technology 🌡️ Extreme Weather Subscribe to RailForge for more fascinating trains, railway technology, mega-projects and engineering stories. #Railway #TrainTracks #RailwayEngineering #Heatwave #TrainTechnology #RailForge
