Emergency officials ordered an evacuation after a freight train derailed in suburban Chicago on Thursday.
The Canadian National Railway train derailed in the village of Matteson around 10.30am local time, WGN-TV reported. No injuries have been reported.
There were no reports of fires or injuries, although one car containing “residue liquified petroleum gas” leaked, the company said.
A fire official said the leak was small and firefighters were able to contain it. Officials ordered residents within a mile of the incident to evacuate.
A message on the village’s Facebook page warns people to plan to for a “long-term” evacuation and take medication and supplies with them when they leave.
“We are now telling our residents there is no danger to any of them at this time and they can return home,” Matteson Mayor Sheila Chalmers-Currin later said. “There is no danger. There is nothing toxic that will harm anyone here.”
