It’s So Cold in Chicago They’re Setting Tracks on Fire to Keep Trains Moving
Extreme cold has been ravaging large swaths of North America, and in Chicago temperatures have dipped as low as -25°F (-31.67°C). When temps reach extremes like these they tend to create unique issues that require unorthodox solutions.
For example, the extreme cold can cause metal on train tracks to contract; pulling up bolts or causing stress fractures, both of which can shut down entire lines and create chaos for systems that transport a lot of people in and around the city.
To combat this, crews will literally set fire to the tracks to keep them warm keep and keep the trains moving; particularly at track switching points where the mechanisms can freeze. Elsewhere crews will soak long pieces of rope in kerosene and burn it next to the tracks to keep them warm.
Check out the videos below for examples of this technique being used earlier this week.
