The northern states of the United States were covered with Arctic cold and the air temperature had dropped to -48 degrees Celsius. Because of this, the Chicago railroaders began to pull on the rails to ensure the uninterrupted movement of the trains.
In cold weather, the metal is compressed and, in some cities, the rails have already begun to collapse. To restore the movement of trains, they must be heated to a certain temperature. As a result, the railroads use the simplest way – it is enough to fix the rails

Workers do not do not define the rails at the foot of the letter. The flames come from gas heaters that follow the rails and keep them warm. Workers also use a tubular heating system and blowers to heat the cold air

Trains can roll along rails, which allows to burn without any risk, because the diesel fuel in the trains burns only pressure and heat, not open fire.
In the United States, because of heavy frosts, they burn the rails: video
In the northern states of the United States, this system is used by almost all railway companies when the temperature of the air falls below 0 degrees. 19659005] This method also allows you to clear the rails of snow and ice.
How do abnormal frosts affect life in the United States? Five states declared the state of emergency. More than twenty people have already died from overcooling. In the state, schools, state institutions, museums and zoos are closed. Heating elements have been opened in the streets of American cities.
