A train was found in Yellowstone River, Montana. It wasn’t some ordinary train crossing a bridge, though.

The train was found derailed on a collapsed bridge. Officials had no idea what happened—if the bridge collapsed because of the derailment or if it just collapsed on its own.

There were eight railcars, but each had something that caused problems. Especially because the bridge collapsed and the train was in the water.

Associated Press, an independent global news organization dedicated to factual reporting, reported the incident.

“The incident occurred at around 6 a.m. on Saturday in a rural area of Stillwater County.” A yellow substance was pictured leaking from the train cars, three which were carrying hot asphalt and four molten sulfur.

The molten sulfur and asphalt were released into the water, and the railroad said those materials tend to harden and solidify when they interact with water. Later, “globs” of asphalt were found downstream, possibly sourced to the derailment.

Water testing began Saturday and will continue as crews work to remove the cars, a spokesperson for train operator Montana Rail Link, Andy Garland, said in a statement Sunday. He noted that Montana Rail Link was working with the Montana Department of Environmental Quality and the federal Environmental Protection Agency on the cleanup, removal, and restoration efforts.

“Montana Rail Link remains committed to addressing any potential impacts to the area as a result of this incident,” he said.

KC Williams, the director of Emergency Management, said drinking water was not affected in Montana.

The train incident has closed many parks to wildlife, not wanting the animals harmed.

The incident wasn’t a big risk and threat to Montana. Nobody was hurt or injured. Still, it left people concerned. The cause of this incident is still being investigated to this day.
