text: The crashworthiness of the flask was demonstrated publicly when a British Rail Class 46 locomotive was forcibly driven into a derailed flask (containing water and steel rods in place of radioactive material) at 100 miles per hour (160 km/h); the flask sustaining minimal superficial damage without compromising its integrity, while both the flatbed wagon carrying it and the locomotive were more-or-less destroyed.[citation needed] Additionally, flasks were heated to temperatures of over 800 °C (1,470 °F) to prove safety in a fire.[citation needed]
