A novel device has been invented by Mr L. C. Keen, of Waiuta, West Coast (says an exchange). The invention takes the form of an automatic danger-signal-ling device for railway crossings. The device does not depend on electricity to do its work, therefore any danger of fusing of the wires or stoppage of electrical power is out of the question. The signal, it is claimed, works automatically by means of the engine attached, to the train when it is within a quarter of a mile of the device. Instantly two signals are set working at right angles and also diagonally to the crossing. At the same time the device shows lights, rings bells, and waves a danger flag. When the engine passes over crossing it comes in connection with another portion of the device, returning it to normal. One apparatus, it is said, will work 20 lines wide at the same time, regardless of the line or the direction the trains are travelling.
