What are we doing? We're trying to move people from A to B and back again without hurting anyone. We're trying to provide the advertised service no matter what, without jeopardizing anyone's safety, no matter what. If it comes down to a "choice" between those two, then we've pretty much failed at the getgo.
Jeopardy is not risk. We accept risk. We manage risk. However, we can only manage risk with an ongoing strategy of reducing risk. There is no other way to manage risk.
So if a railroad professional takes the position that "everything is safe enough, the engineer/conductor/dispatcher/whatever should just do his/her job according to the rules or not come in to work," a big, critical, vital point has been missed.
Human beings don't have to try to do things deliberately to hurt people to actually hurt people. Human beings kill others while trying to do the right thing. That's one point.
We can prevent a lot of that. That's the other point.
