Personnel maintaining or repairing the railway tracks or signaling device around tracks may experience the sensory disorder when they do routine works for many hours and they may not recognize the approaching train, leading to train accidents. In order to prevent such train accidents that may occur because railway track workers are unable to recognize the approaching train, a safety-equipment is developed to make the approaching train send radio signals. We developed the new alarm equipment for protection of trackside maintenance workers using bone conduction speaker.
