So now we hear that the Amtrak Northeast Regional Train 188 that derailed in Philadelphia was traveling at 106 MPH in a 50 MPH zone and that it might have been hit by some sort of projectile.
For the sake of discussion, let's assume it was hit in the windshield by a bullet or a rock. How would that affect the speed of the train? Whether or not it was hit, it was still going twice the speed it was supposed to go.
I smell something that is over-ripe.
