The Blast Furnace at Newcastle. Automatic Train Control. Many inventions have been brought out for the purposeof giving the driver of a locomotive an automatic warningthat the signals are against him, and also for applying thebrakes at the same moment. A new form of train con-troller was recently tested with success on an importantBritish railway. The apparatus consists of an interceptorplaced between the rails and connected with the ordinarysignals, together with a set of gear on the locomotive whichoperates the whistle, puts on the brake, and if desired also closes the engine regulator. The interceptor takes the formof a curved metal plate hinged near one end and supportedat the other end by a weight in such a way that the highestpoint of the curve is about 5 inches above the rail the signals are clear the interceptor is depressed by thelocomotive passing over it, but if the signals are not clearthe interceptor remains at danger and gives
