The air is frozen and dawn is taking over the blue hour as Canadian Pacific 8137 (AC4400CW) leads a grain train towards the signal at Keenesburg, Colorado.
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!)
