Abstract
A method is for determining a status of a track section of a railroad. Each end of the track section is connected to a respective detector. One of the two detectors transmits a current along the rails of the track section towards the other detector and receives a current transmitted along the rails of the track section from the other detector. The track section is further equipped with a computer in communication with the two detectors. The computer calculates an instant value of the status of the track section as a function of an instant vector based on a measure of an intensity of the current transmitted by a first of the detectors as measured by the first detector (Txl1), a measure of an intensity of the current received by the first detector as measured by the first detector (Rxl1) and a measure of an intensity of the current transmitted by the second detector as measured by the second detector (Txl2).
