No, I'm a rail operator. I am basically there to pilot locomotives back and forth - i.e. be the eyes of the driver in instances where they can't see what's ahead/behind. I do shunting, brake inspections, and berthing into our rail yard. It's a good job, though the shift work is tough (ironically it's the day shifts I can't stand; I love the evening and night shifts).
And the sound isn't annoying enough to need headphones. It's just a "gods damn it leave me alone" kind of noise. Like how professional chefs hate cooking at home - aside from my kid's wooden train sets I want nothing to do with trains outside of work.
Anyway, I'm very anti my job at the moment because the managers reneged on a deal we made. I'm tempted to call in sick for my shift tomorrow just to make them scramble.
