For years, I've joked with fellow coworker and RailPictures contribuitor Elijah Cross about getting a very long telephoto lens and shooting the intermediate pair of semaphore signals between Levy and Wagon Mound. Well, this is that shot, pulled far out, to about 310mm on a Sigma 150-600. Something a little bit different than the normal semaphore shot usually seen here.
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.
