CN has been updating the mainline around the Shelton Junction area to help increase train efficiency in the area. With that the signal system is getting updated too. These classic search light signals look like they are being replaced where work is going on. Here at Iron Jct a southbound T-bird is lined up as the blue hour hits after sunset.

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"!)
