Five Montana Rail Link EMD six-axle locomotives, used as a helper set on Bozeman Pass, head downgrade back to Livingston glinting the setting sun on October 10, 2005. Westbound trains get plenty of help by this set, with MRL No. 390 leading a SD45-2 and a trio of SD45s for a total of 100 cylinders producing 10,800 horsepower.
