There is no trickery here. The "797" stopped in Highfield to work the MMID interchange giving the sun time to set and the fog and snow to get heavier. At 5:50PM the train finally departed Highfield bound for Hanover allowing me to get a night, silhouette, pan shot at 1/10th of a second.
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!)
