offered to come back for more interviews should they need it as the investigation continues. he says the last thing he remember was ringing his bell as will they went through the philadelphia station, north philadelphia station. he says he didn t have any illness or any fatigue. he s been doing this route for a while now five days a week back and forth between new york and d.c. he just doesn t remember the crash. minutes before the crash, an assistant conductor on his train recalls hearing over her radio conversation between bostian and an engineer on a nearby accept take oig, that engineer told bostian he had just been hit by a projectile and bostian responded i was hit, too. another acela train also reported to nbc news that he was hit with a projectile. here is robert sumwalt with the ntsb yesterday. he recalls ringing the train bell as he went through the north philadelphia station, that s not a thunderstormnormal station
windshield pattern? well, they will use again, this is the fbi doing this investigation of that particular part of the wind shield as i understand it. they will use their technology and whatever other means they have whether it was a rock or a bullet or some other type of projectile. they will figure it out that s what they re good at, these crime investigations. we don t know that it s a crime but it very well could possibly be a crime. how concerned are you when you hear the news that there was that local commuter train that reported having a wind shield problem, the septa train spokesperson saying trains through area has had projectiles thrown at them in the past also acela express southbound in that general area had something else reported proceed jek toil thrown
i may have said horn. he s priored to sound his ed torequired to sound his bell as he goed past a station stop. and he did that. he recalled doing that. but he has no recollection of anything past that. joining me now from philadelphia s amtrak station, adam reese. what more do you know that you can tell us about the ntsb s interview with the engineer brandon bostian? reporter: they tell us he s been very cooperative offering up more support. all he remembers as you heard ringing his bell as he passed through the north philadelphia train station. he wasn t fatigued he wasn t ill. this was a regular route for him from new york to d.c. and bag.ck. did he it five days a week. he just doesn t remember the accident. just before the crash, an assistant conductor heard over her radio a conversation between bostian and an engineer on a septa train a local metro train on a parallel track. he tells bostian i was just hit
okay. you know this stretch of track really well. i understand there was a 50 miles per hour speed limit. could a train that train 188 given the number of cars, speed at which it was traveling could it have safely made it around the bends, was that even a possibility? what the 50-mile-an-hour speed was what we call a permanent restriction meaning that the radius and the various other features of the track, there is a formula that the track engineers use. and they factor in a safety factor. so 106 miles an hour was that impossible? did it never have a chance of surviving? well, that s not my area of expertise. but i would say it s 106 miles an hour is probably not possible. can i ask you about the ntsb reports investigating that something may have hit the wind
that had train from going so fast into that turn. so it s not happening and that s the great up fortunate part about what is going on in congress right now. but sir may i ask you positive rain control, that was something that was mandated after the 2008 chatsworth crash. you can tell us how the mapndate came about and how it has not yet been implemented? amtrak was on schedule to complete the positive train control by the end of this year. and i think they would have done it. unfortunately, this is a very, very expensive process and we have tens of thousands of miles of train track around the nation. some of it in these very, very heavily used coryridorscorridors. you mentioned the chatsworth incident out seedside of l.a. about so that these are critical
