Abstract
The present invention refers to a method for detecting a break in a railway track, system for detecting a break in a railway track (1) and device for detecting a break in a railway track (500), in which a first track (101) and a second track (102) are connected defining measuring sections (302, 303) and electrical detection networks (M1, M2), in which a device for detecting a break in a railway track (500) is coupled to said tracks (101, 102) and arranged to measure at least one electrical parameter of at least one electrical detection network (M1, M2) and selectively promote an output (502) that indicates a state of at least one track (101, 102).
