Greeley, Colorado has that 'land that time forgot' vibe as telegraph poles and old grain businesses line the tracks that go through town. UP 1820 (SD40N) heads into town and will continue through to the yard in LaSalle, Colorado.
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.
