This is a simple composition, characteristic of the early 20th century Precisionist school. There’s little in the frame that isn’t essential. The pylons, wires, and tracks all converge at a vanishing point at the edge of the frame, suggesting, but not showing, a more expansive network of wires, tracks, and, for better or worse, human dominance over nature.
Telegraph poles with multiple “code lines” were once a common feature along American railroads. They are distinguishable from ordinary power or telephone lines by their multitude of cables, often occupying several crossarms. The wires typically include a power bus plus separate leads for the signals along the route, with various more efficient encodings used as technology improved.
They’ve been mostly supplanted by more modern SCADA systems that don’t require so many individual wires.
