SAN BERNARDINO, Calif. (AP) - At least 13 tanker cars went off the rails in San Bernardino Tuesday, and some leaked an unknown substance, but authorities said there were no injuries and no threat to residents and businesses.
The freight train derailment prompted precautionary evacuations of several nearby buildings and a homeless camp along a riverbed near the 7200 block of Cajon Boulevard.
A gas- and alcohol-based liquid leaked from three tanker cars, but officials did not immediately identify the substance. An initial check by a hazardous-materials team said there was "no threat to the community," the San Bernardino Police Department said in a tweet.
Crews were working to secure the leaking tanker cars, according to officials with the San Bernardino County Fire District.
Surface streets were closed, but Interstate 215 just north of the accident site was open.
Investigators will try to determine what caused the derailment at the foot of the southern side of Cajon Pass, which carries rail and highway traffic over mountains about 60 miles east of Los Angeles.
More information will be posted as this story develops.
