I've heard it shrug. My brother tried working for the railroads. He quit within a month. It's lonely, it's dangerous, and you don't want to know how reckless the trains are being run in the US (around the midwest). There are train overpasses in my area which are cracked and falling apart (I can send you pictures).

The number of derailings, the amount of hazardous material (chlorine is a blip), and the skill drain has brought the rail industry to a crisis point. We're just waiting for its Hindenburg moment.
