Railroads inspect their track often. The US has been roasting with a historic heatwave. Sun kinks can form between the time a hirail truck passes and the next train. Extreme heat can weaken ties, tieplates, rail, etc. That's why every rail line in the south had a heat restriction on it last week and most midwest lines..
Plus that area got hit with bad storms. Possibly an unknown subsidenced in the ballast; over time and trains running over it made the track finally fail (with the worst kind of train on it. Loaded ethanol). All things that have to be looked into.
