  1. They do not run them until the wheels fall off. The wheel bearings have temperature sensors on them and when they go bad, they get hot and the engineer is supposed to stop the train and call maintenance to change the bearing. And they do get routine maintenance. The mechanic repacks the wheel bearing with new grease, inspects the beating while he has it out, and changes the grease seal on a regular basis.

  4.  @belllpatrick  You are the joke because you think you are smarter than the experts. You are not nearly as smart as you think you are.

  5.  @chooch1995  hhmmm. 🤔 It was not "who decides" that caused the wreck -- it was a wrong decision that caused it.
