Pathfinder and FQ13, I run the heavy stuff, coal, grain, rock and etc. And yeh the 12 hours can be rough on the system. Like you've experienced with that BNSF crew, they HOG-OUT short of their destination and had to wait for the relief crew. So by the time they actually got to a tie-up point or in the hotel, they were on duty for well over 12 hours. I have had a few cases where we were hog-out and they had no availible crews or vans and had to stay on the train for another 8 to 10 hours until they had someone to come get us...The pay is great, but you run out of food,can't get comfortable in the cabs, alot of things that can make it miserable. And yes the headlights will burn the Sh*t out of you!!!
