From CBS in Philadelphia:
SEPTA spokeswoman Jerri Williams says they don’t know what the projectile was. It broke the engineer’s window around 9:25 p.m. Tuesday near SEPTA’s North Philadelphia station. No injuries were reported.
Williams says the Trenton-bound commuter train was stopped and the incident was being investigated when the Amtrak derailment happened about 3½ miles away.
There is no indication, we are told in reports, that this projectile had anything to do with the Amtrak crash in Philadelphia.. But that may not be enough to quell the numerous questions that will arise as this situation develops..
Also, the ‘black boxes’ have been recovered and have been taken to Delaware for investigation, according to JON HURDLE and RICHARD PÉREZ-PEÑA of the NEW YORK TIMES..
