A variety of power has been used over the years in Oregon's Blue Mountains. Heavy grain trains, such as this GS-BRSE, used to be split in two and assigned 2 SD40-2s on either end. Today's operations see full grain trains with 3 4,000 horsepower units on the point and 4 more 3/4 of the way back. This train is now draped over the top of Kamela summit with the DPUs still working the back half of the train over the top.
