A spokeswoman for the Southeastern Pennsylvania Transportation Authority says there’s no indication that the incident is related to the derailment.

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.

Williams says Amtrak dispatches SEPTA’s Trenton line and was aware of the incident.

Seven people, including a Naval Academy midshipman, were killed and dozens more were injured in Tuesday night’s Amtrak derailment. The conductor of the crash was also injured but survived.

Meanwhile, the Red Cross says it is providing counseling and support for survivors.

“We will do everything we can to assist families who had loved ones on that train,” said Mayor Nutter at a press conference on Wednesday.

“This is the Amtrak family, we are very saddened by what has occurred,” added Anthony Coscia, of Amtrak.
