Glowing Signal Gantry Over Rails in Drizzle

Red and yellow signal heads glow intensely against a backdrop of heavy, low-hanging clouds in midsummer Changsha. Rain falls as a fine, horizontal drizzle, turning the steel trusses of the signal gantry into dark, wet silhouettes. The structure spans wide railway tracks that converge sharply toward a distant vanishing point near the storm surge barrier. Water beads on the metal surfaces, catching the artificial light and creating sharp, scattered reflections. The scene is dominated by the practical geometry of the infrastructure, where the bright circular lenses cut through the gray evening gloom. One raindrop rests on the lower edge of a signal housing, hanging precariously before the steel. The wet rails gleam with a mirror-like sheen, reflecting the red glow of the signals.
