The FBI will investigate a report that the Amtrak train involved in this week’s deadly derailment was hit by a projectile before crashing, according to news reports. Eight people were killed Tuesday after New York-bound Amtrak train 188 derailed north of Philadelphia’s 30th Street Station. According to a CNN report, a SEPTA train was struck by an object around the same time. A conductor told the NTSB she thought she overheard engineer Brandon Bostian tell the SEPTA train via radio the Amtrak train had also been struck.
