If a car was completely destroyed, then they were going way to fast around that bend. The fastest they go on the straight section along there is barely faster than the fast traffic on I-95 (I’ve been on those trains many times). Somebody screwed up.
Alright, just saw a picture of the engine and it did not look like it severely impacted something, no blood so not even a person.
Something caused the engineer to deaccelerate and the train to derail (also causing the catenarys to cross causing a large explosion of sparks). The next car jackknifed and the following car hit somthing, maybe a bridge support.
If the engineer was alert enough to brake like that then I have a hard time seeing it as his/her fault. Also it just left PHL and was coming into Trenton so I have a hard time believing he wasn’t alert.
A problem with the track is very hard to see from the engine so it would have been something obvious for the engineer to brake.
A train derailer is bright yellow.
