After a repair to a washout on the Mon Line, an endless parade of coal loads and empties go up and down the NS Mon Line at a frequency I've never witnessed before. N21 heads north through the double track between GATE and ARK meeting counterpart N22 at Clarksville, PA.
An ongoing/growing album of photos that IMHO reveal the awesome, but seldom seen beauty of railroads because most of us don't go out after sundown or before sunrise. From dusk to dawn, lights are on! (And I continue to find new "Lights In The Night"!)
