LIVINGSTON, Ky. (NewsNation) — Residents of Livingston were allowed to return to their homes Thursday after a train derailment and fire forced the community to evacuate.

“CSX and local emergency responders in Rockcastle county, Ky. have extinguished the fire that resulted from yesterday’s train derailment just north of Livingston, Ky. Specialized equipment has been deployed to conduct air monitoring in the area and local authorities have determined it safe for residents to return to their homes,” a statement from rail company CSX read in part.

At least 16 cars derailed, and two of them carrying sulfur caught fire.

It’s believed that sulfur dioxide was released into the air, which can cause respiratory problems. One crew member was treated for minor injuries.

Kentucky Gov. Andy Beshear declared a state of emergency and the train company CSX is covering the cost of hotel rooms and food for evacuated residents.

“We will work together with local authorities to secure the area and safety is our top priority as we develop a recovery plan,” CSX said in a statement Wednesday.

Beshear posted to social media that he’ll share more information as it becomes available.

“At this time, one home has been evacuated and teams are working to evacuate one more. Please stay clear of this area,” Beshear said.

Officials with the Rockcastle County Sheriff’s Office said the area is “extremely remote” and authorities were still assessing the situation.
