A tractor-trailer attempting to turn around at a dead end was struck by an oncoming train in Bell Township, Westmoreland County, Tuesday morning.
Officials said the truck was carrying chemicals that spilled inside of the trailer.
Channel 11's Brittny McGraw reported that the crash derailed some train cars and damaged the tracks. Officials from Norfolk Southern said they're working to make the repairs and did not give a timetable of when they should be complete.
Westmoreland County Emergency Management spokesman Dan Stevens said the driver's GPS was outdated and sent him in the wrong direction.
"The rear of the trailer got onto the railroad tracks and it looks like an eastbound train struck the rear of his trailer," Stevens said. "Sometimes GPS units do not have the most current maps. This used to be a road that would take you into Avonmore. That road has been closed for quite a few years."
Emergency workers said the driver was being treated for a head injury. There is no word on his condition.
