The iconic Pennsylvania Railroad color position light signals have stood on the Pittsburg Line since the days of steam and have seen four railroads. Sadly, they are all being replaced in favor of modern positive train control cab signals. On a clear April night, PT 254 at Lilly stands guard over trains moving up and down the West Slope. Nobody knows for sure how much longer this signal will stand, as crews have been making progress and are currently just East of Altoona.
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"!)
