Indeed, that changes things a bit, plus it was 8 cars. Weren’t there something like 16 or more connected to the train that crashed?
Regardless, after a point it doesn’t appear to change overall acceleration that much since it reportedly took about a minute to go from 80 to 106 in the case of this train crash incident.
I’ll bet with almost 100 % certainty that the analasyes from the N.T.S.B. will show that the windshield will show that what hit that windshield is staring them right in the face.
Metal from the catenary lines poles, the the rail road ballest rocks, and traces of copper from those copper electric cables hitting that windshield.
Isn’t there also a cat walk just about 50 yards from the engine ?
They will find traces of metal on that engine from that cat walk from the engine hitting it.
Notice that the N.T.S.B. is stepping away from the story and theory that some kind of projectile hit that train ?
