Thank you for the education Jim.These are the heaters. The fires that you see are fueled by propane to heat these switches and tracks, the ties are concrete. From experience the Burlington Northern Santa Fe rail lines that owns the tracks has found using propane/natural gas is the best source of heat and is economical to use, in the Chicago metropolitan area. They have installed small orifice tubes that the fuel flows out of, these are buried just under the grave along side of the switches and tracks, they are then ignited to burn, similar to a gas grill or a gas fire place orifice tube.
These have been in placed and are used when the temps drop below a certain set point in ambient temps. It is just as a I said in my pervious post that the millennials and non-local news people were amazed at the burning of this fuel to heat the tracks. They simple state that the tracks were on fire, never giving the full story. Since they are not from Chicago IL they have never experience this.
Electrical cost are higher then natural gas/propane in our area. As an example I have a 2,000 sq ft home using natural gas to heat (house kept at 68F), cook, run my fireplace, heat our water and dry the clothes. The gas bill is $62 a month. Electricity is used only to run the lights (LED'S), TV/radio and provide power for my DC fan motor on the furnace+ some parasitic uses such as cell phone chargers and so, forth. This usually cost me $96 a month.
