Would follow the rules even if something bad was going to happen?

I got this in an email from one of my co-workers:

“The Good news: It was a normal day in Sharon Springs, KS when a Union Pacific crew boarded a loaded coal train for the long trek to Salina.

The Bad news: Just a few miles into the trip a wheel bearing became overheated and melted, letting a metal support drop down and grind on the rail, creating white hot molten metal droppings spewing down to the rail.

The Good news: A very alert crew noticed smoke about halfway back in the train and immediately stopped the train in compliance with the rules.

The Bad news: The train stopped with the hot wheel over a wooden bridge with creosote ties and trusses (In defense of the crew, according to Sixgun Jr., the crew tried to 'splain to higher-ups but were instructed not to move the damn train!).”
