  Circuit for telegraphing with currents induced into the telegraph line by a neighboring power line.
 EMI1.1
 should first be explained with reference to FIG. 1 of the drawing, and the elimination of which is the purpose of the present invention.



     Assume that the line labeled a in Fig. 1 ssi the contact wire of an electrical alternating current railway and b a nearby teiegraph line with two Morse code devices c and d and the two telegraph keys e and f.



  The windings of the magnet systems of the Morse code c and d are then once immediately
