As exhaust rises into the illumination of a light tower, Rio Grande EMD SD40T-2 No. 5371 rests next to the venerable sand tower at Helper, Utah, on the night of October 23, 2007.

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!)
