As much of a major inconvenience it is having trains block our ways, it's an integral part of our economy. When you really think about it, they have deadlines they have to reach and they need to work at the times necessary to meet these deadlines. It also depends on Koch Fertilizer and when they can fill the cars and ship them to the yard. Take into account the shift hours at Koch, then factor in the shift hours at CN, and that's just how it works. Those guys have to do the job when they get the chance, and what they are hauling most of the time is how you get to work and how you put food on your table. Yes it's annoying sometimes and seems unnecessary, but they don't do it just for fun.
And just for thought, some of those workers may work late and they probably have errands to run or groceries to grab but most stores aren't open late for them. If they came on here complaining, I'm sure it would cause a huge stir.
