Method for determining a status of a track section of a railroad, the track section (1) being insulated form adjacent track sections (2, 3) and comprising first and second ends (11, 12), the first end, respectively the second end, being connected to a first detection device (14), respectively to a second detection device (24), one detection device among the first and second detection devices transmitting a current along the rails (5, 6) of the track section towards the other detection device and receiving a current transmitted along the rails (5, 6) of the track section from the other detection device, the track section (1) being further equipped with a computing unit (19) in communication with the first and second detection devices, the computing unit calculating an instant value (S1) of the status of the track section as a function of an instant vector of measures that comprises: a measure of an intensity of the current transmitted by the first detection device as measured by the first detection device (Tx1l); a measure of an intensity of the current received by the first detection device as measured by the first detection device (Rx11); and a measure of an intensity of the current transmitted by the second detection device as measured by the second detection device (Tx12).
