Photos showing the railroad pole lines. The pole line used four basic electrical circuits - telegraph, telephone, signaling, and power. Modern technologies of fiber optics, microwave, radio, satellite, and computers have been replacing the pole lines.
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"!)
