The Exhibit of the Union Switch and Signal Company both being obtained from the same source—generally a storage battery—the directcurrent being converted into alternating current at the proper time and in the propercircuit by a very simple method adding practically nothing to the cost or complication ofthe apparatus. The use of currents of different character for operation and indicationis an absolute safeguard against the misleading manifestations which might otherwiseresult from faulty insulation, and the switches and signals are protected against impropermovement, which might result from stray currents through faulty or broken-downinsulation, by means of a magnet cut-out in connection with each switch and signal,which opens the circuit when a wire leading to it becomes crossed with a live cut-out acts independently, without affecting any other switch or signal in thesystem, a decided improvement over anything heretofore used or known for thispurpose.
