The Commuter Train that was an Amtrak Train was derailed off the Train Tacks by a Projectile, Threat Matrix Ping Lucy!
its a case of two seperate trains..the one that we know was hit by the “unidentifed” projectile...and the other the one that crashed..
given that they dont know what sort...of projectile hit the one train...I doubt that we will ever know what relationship to the other train wreck there may be.
