Coal is 39% of U.S. railroad tonnage and 19% of their revenue. See: https://www.aar.org/BackgroundPapers/Railroads%20and%20Coal.pdf
If cold fusion succeeds US railroads will be in deep trouble. Cold fusion will have much wider effects than people realize. Coal use is already declining as shown on p. 2. It peaked at 1.13 billion tons in 2007. It has fallen to 917 million tons. This is mainly because of natural gas, but also wind and solar. 93% of coal is used to generate electricity. Coal production is also declining in China. - Jed
