There is only a 'rumor' based on third party info about the crater. It has not been 'reported' anywhere else.
What has been reported is that the engine had a cracked windshield, but otherwise very little damage.
AND, a SEPTA train had something crash through it's windshield mere minutes before this crash.
See post 252
Yes, I should have emphasized “unconfirmed” report of a crater.
Let’s see where the data leads.
Having ridden SEPTA trains for decades in and around Philadelphia, I can say that it's not that unusual for local kids to toss rocks at passing trains. It always sounds very loud, but is relatively harmless except for putting lots of dents in the sides of the rail cars.
