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 growing album of photos that IMHO reveal the awesome and seldom seen beauty of railroads in the dimming of day to dawn's early light! From dusk to dawn, lights are on! (I still find new "Lights In The Night"!)
