BNSF is busy installing CTC on their double track section of the Aurora Sub between Graf near LaCrosse, and CP 1462 near Savanna. Alot of this section of the railroad is still TWC/ABS territory, which limits what BNSF can do with train traffic. With the installation of CTC these classic CBQ era signals are going to be replaced. A story being told all over railroads in 2015.
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"!)
