The PRR Position Light Signals at Lilly, PA overnight in October, 2017 as the light from an approaching eastbound pierces through the night air and the stars slowly fade.
Of note is the contraption to the left center of an old pulley system used by the PRR to allow water to the locomotives since Lilly was a water stop and full interlocking on the West Slope.
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!)
