Two U.S. trains slipped off their routes on Thursday, two days after a deadly Amtrak accident near Philadelphia, according to reports.
Parts of a freight train derailed in Pittsburgh on Thursday morning, leaving some cars overturned or detached from their wheels, according to local station WPXI. No injuries were immediately reported.
A minor derailment also took place in South Carolina with no injuries reported, according to Georgia outlet WRDW. The engine compartment of another Amtrak train caught fire in Milwaukee on Thursday afternoon, though no passengers were hurt.
The incidents come as the Philadelphia accident—which left eight people dead and more than 200 injured—places scrutiny on the state of America's infrastructure and railroads.
