A train has derailed off of a bridge and into the Yellowstone River. This train was carrying hazardous materials, 3 of the train cars carrying hot asphalt, 4 carrying molten sulfur. According to Montana Rail link, two other train cars were carrying sodium hydrosulfite, a corrosive substance, although it did not enter the water. The sodium hydrosulphite was transported, and was moved off-site.

The derailment occurred at approximately 6:45 a.m. on a Saturday. Nobody was injured, but it is still unknown if the derailment caused the bridge to collapse or if the bridge collapsing caused the derailment.

Although Montana Rail Link Public Information Officer Andy Garland says, “Both of these substances harden and solidify quickly when interacting with water and modeling suggests that significant downstream movement of material is unlikely, MRL officer Couch says, “All of our water comes through the river for our wells and our irrigation and everything.” Because of this incident, state officials are warning the public to avoid parts of the river due to potential contaminants. Later, asphalt globs were found downstream, likely coming from the derailment. Even though there is no immediate threat to Yellowstone County, many people are still worried about the vulnerability of the chief water supply.
