As Union Pacific GE AC4400CW-CTE No. 6072 sits on a nearby track, UP AC4400CW No. 6940 gets some work done in the “Wheelhouse” at North Yard in Denver, Colorado, on the long night of December 22, 2012. As can be ascertained by the monicker, the building is used to do locomotive wheel work and is fully-equipped with a wheel lathe.
A continuously growing album of photos that IMHO reveal the awesome and seldom-seen beauty of the railroad world from the dimming of day to dawn's early light! From dusk to dawn, trains roll on! (I'm still finding gems of sunset-to-sunrise surprises!)
