The Good News: It was a normal day in Sharon Springs, Kansas, when a Union Pacific crew boarded a loaded coal train to head on the long trek back to Salina.

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

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

The Bad news: The train just happened to stop with the hot wheel on top of a wooden bridge built with creosote ties and trusses.
