- Montana Rail Link is investigating a train derailment directly across the Clark Fork River from Quinn’s Hot Springs Resort, southeast of Plains.
- At least one railcar carrying hazardous materials — butane, a form of liquefied petroleum gas — derailed around 9 a.m. Sunday, but MRL and local first responders confirmed that there was no release of hazardous materials. The only cargo known to have spilled was some powdered clay and multiple box cars of Coors Light and Blue Moon beer, in cans and bottles. There were no injuries in the derailment. No cars caught fire.
