  "definition": "A circular visual indicator in a British train cab, part of the Automatic Warning System, that shows a black disc normally and a yellow and black radial pattern after the driver acknowledges a warning of a restrictive signal ahead. The pattern remains displayed until the train passes over the next AWS track magnet. A clear signal produces a bell and leaves the disc black, while a restrictive one sounds a horn.",
