Well, if you want the promotion then you have to play the game. I did it in 2005 for the UP and then again with Amtrak in 2007. Make the most of it and enjoy the benefits of working in the cab vs. on the ground lining switches in the cold/heat, walking to the back of your 8900' train, etc.
It used to be $686/week...no held away, no meals, ot only after 80 hours on duty. Usually a net check every two weeks was about $850. You tough it out...bad agreement though.
