It's just before sunrise as BNSF ES44C4 No. 7035 brings up the rear of this loaded ballast train from Cheyenne, Wyoming to Bijou, Colorado as the train negotiates the numerous hills near Gunbarrel just northeast of Boulder, Colorado on September 20, 2015. The "Flatirons" can be seen in the background.
Pictures taken with the strong contrast between Rail and Light in Dawn/Dusk/Sunrise or Sunset.

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!)
