Claim 0:
1. A method for estimating one or more actual electrical parameters of a track circuit comprising a transmitter, a receiver, and a track section interposed between the transmitter and the receiver, the method comprising:
outputting by the transmitter, over the track section and towards the receiver, at least one signal comprising at least one data packet part;
decoding the at least one signal received at the receiver to determine the at least one data packet part received;
simulating one or more signals by varying an actual value input for one or more parameters of a set of electrical parameters of the track circuit, each simulated signal corresponding to an actual set of values input for the set of electrical parameters;
comparing each simulated signal generated with the at least one signal received at a receiver until finding at least a part of a simulated signal that matches a corresponding part of the signal received at the receiver; and
estimating as the actual electrical parameters of the track circuit the actual set of values of the electrical parameters corresponding to the simulated signal that matches the at least one signal received at a receiver.
