This application relates to a method for calibrating a track circuit as provided. The track circuit includes a transmit processing unit, a receive processing unit, a plurality 5 of rails coupled in series to form a track section having a first end and a second end. The transmit processing unit is coupled to the track section adjacent the first end. The receive processing unit is coupled to the track section adjacent the second end. The method includes operating the transmit processing u nit so that a first voltage is applied to the track section, operating the receive processing unit to detect a first current 10 signal, and if a parameter of the first current signal is not within a predetermined range, then communicating with the transmit processing unit so that the transmit processing unit automatically applied a second voltage to the tract section, the second voltage having a different magnitude than the first voltage. 938703>
