A railroad signalling device is sharply focused under a featureless grey sky, a pole rises up from the bottom center with something that looks like a ladder along it that seems to be too thin for that purpose. The signal has two blades, we seem to be seeing the black back side of one that is behind and nearly horizontal, the one in front is angled slightly down and looks reddish-purple with a white stripe painted near it's end, the blades have colored red and blue lenses attached to their opposite sides near the center.
