Missouri, Illinois, Kansas, Nebraska, Wyoming, Colorado and more will experience slower railroad trains until the heat subsides.
"Once the temperature stabilizes," Davis said, "then we can begin looking at increasing the speeds again back to where they were."

The combination of heat and a lack of rain has caused further devastation in the drought-ravaged south-central United States. With soaring temperatures outside, humans are not the only ones seeking more temperate climates indoors.
Ants and cockroaches, likewise parched, might seek water in people's homes.
"You've got a constant supply of water from households and a decreasing supply of water from the environment so the result is more movement indoors to get more water," said Joseph Kunkel, a University of Massachusetts biology professor who researched cockroaches for 25 years.
In southwest Florida, ants are invading local homes and offices, according to local affiliate WZVN.
Cape Coral homeowner Aida Cardona told WZVN that she is under attack, with hundreds of ants invading her home.
Kunkel said that the ants are typically dormant during the winter and more active in the summer months, when they travel in single files into homes in search of a steady food and water supply found in kitchen pantries.
Likewise, he said cockroaches, "independent operators" who "don't care about anyone but themselves," will travel indoors during summer months to escape the scorching heat and search for, "water, food, and a mate, in that order."
