MODERN RAILWAY SIGNAL.
The Great Western Railway of England has decided to equip its' chief main lines and 2000 of its locomotives with a new and wonderful system of signalling. The .engine itself will heed the warning signal and will, apply its own brakes.. In the vicinity of each signal a third rail is fixed between those upon which the wheels run. Hanging below the locomotive is a spring contact shoe which touches the rail as the train passes over. Should the signal be at danger, electrical impulses puss into the cab of the locomotive, for the shoe is lifted by the third rail and closes a switch. A bell rings in the cab, and the brakes are applied automatically.
