Chicago Is So Cold That Railroad Tracks Have To Be Lit On Fire

When it gets to be several degrees below freezing, the metal of the train tracks can contract to the point that it will pull up the bolts holding it in place, or even stress fracture. Crews will soak long pieces of rope in kerosene and burn it to warm up the tracks, expanding them back into place for repairs. Once the track is warmed, it’ll be re-bolted, or welding repairs can be affected on the broken tracks. This is vital to continued operation during cold temperatures.
