Rio Grande 2-8-2 K-37 No. 491 takes a spin on the turntable during the blue hour on the evening of November 17, 2014, at the Colorado Railroad Museum in Golden, Colorado. The big Mikado (for three-foot narrow gauge, that is!) was originally retired in the 1960s, and restored to operation earlier this year.
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!)
