As post #2 indicates, that was a separate train maybe 20 minutes and some distance from the train Bostian was negligent in operating.
Yep he read the reports of the other train getting hit so thought he could use that as a way out!
Commuter trains share the same roadbed. there are 4 lanes two for amtrak two for the local trenton line. the inbound trenton train hits north philly station at 8:45 pm about 20-30 minutes before the outbound amtrak passed the same station leaving 30th street at 9:09. if i were the engineer going to new york i would be on radio with the inbound trenton engineer.
