How And Why Did Conductors And Engineers Get Their Outfits?

 Polyester is a bad idea if you are around heat. I was on many fires in Kentucky while wearing the KDF uniform, with poly in the trousers and shirts. The bosses did not want anyone wearing blue jeans because that would not look professional. They eventually let us wear Carhartt pants, and they issued a small number of Nomex pants for fire fighting. I think the overalls are a great idea because you don't have to hitch up your pants all day long, and a trainman needs his watch within easy reach. Those upper pockets are handy.
