"Safe" for the passengers then, but is nobody else truly around that could get hurt by the derailment?

Also, how many tied to the tracks are literally murderers who if not themselves killed in this manner, will go on to kill many more again?

Or did these people - cult members? - have themselves tied to the tracks willingly, wanting that easy death rather than slavery of the continued drudgery of existence?

I... might be overthinking this.:-P
