Abstract

Apparatus for testing the insulation of a direct current track circuit in a railway line provided with a plurality of direct current track circuits adjacent to each other, such circuit comprising a pair of tracks (R) made up of parallel metal sections (B) between which it is possible to apply an electric voltage, each direct current track circuit being separated from the adjacent one through electrically insulating joints (G).
