Fox just said an eyewitness heard an explosion and saw flame at the moment it happened.
Sound like an IED to me.
Looked like that front car was blown, it did not just roll over.
Could have been the overhead catenary arcing when the train went over. it’s possible the “explosion” was just the train derailing, as some people will call any loud noise a explosion.
“Fox just said an eyewitness heard an explosion and saw flame at the moment it happened.”
I’ve seen 20-30 feet of arcing come off those catenaries. 25 hertz loud enough to knock the phlegm out of you.
