Rock Springs, WY area, looks pretty remote. 50+ cars involved, 20+ cars on fire, massive flames! https://wyo4news.com/news/train-fir...9kk4CzXw7rE3KhUN0JO20d1uO2k8FfMTvwiZKzs2kODsg
100 foot flames! You could feel that from a mile away I bet! Sure hope no one was harmed, cause that's a dangerous combo of flammables!!
Ignoring the YT commercial, you can get to the actual footage. But what the "reporter" is saying is hogwash, as usual.
Heat generates 'sun kinks' as the rail tries to expand from the heat. Cold generates pull-a-parts and stretch breaks as the rail shrinks. A flat wheel often acts like 'cold chisel' and create stress points that can fracture the rail as it is being stretched by the stresses of the cold.
