One of the iconic images we have of the old West is the train robbery. It is mostly a polite affair where the bad guys are either already inside the train and proceed up and down the aisle to collect the goodies from the passengers (cue the pretty lady who the bad guy allows to keep one sentimental piece of jewelry) or they block the train track so the conductor stops and the band of merry bad guys go gain, politely go confiscate goodies at gun point.
I am not saying that did not happen, but what I have seen in different papers the most is terroristic stuff like above.: Make the train derail, damned be the lives of those inside and they go pick the remains like hyenas.
Train traveling was a dangerous affair back then. Beside the robbers, you had the Tramps (Hobos) who would derail a train out of revenge for being kicked out and the just plain crazies that liked to see things break and blow.
“Fun” Fact: When a train derailed, the ones more likely to die were the engineer and the fireman and the cause of death would be crushed to death against the scorching hot boiler. Basically like bacon on a pan with the cast iron press on top.
