[VIDEO] So far Chicago has experienced one major cold snap this year. And I learned over the last few years that to keep Chicago's rail lines in operation that fire is used to keep the switches from freezing up in the winter time. You read this almost three year old article about this process from The Atlantic.
We see a track worker in Chicago starting this process in the wee hours of the morning. This was captured today on the Railstream YouTube channel. I think this scene took place on the tracks going through Chicago's west side.
