METHODS AND SYSTEM OF AUTOMATING TRACK CIRCUIT CALIBRATION
First Claim
1. A method for calibrating a track circuit, the track circuit including a transmit processing unit, a receive processing unit, and a plurality of rails coupled in series to form a track section having a first end and a second end, the transmit processing unit coupled to the track section adjacent the first end, the receive processing unit coupled to the track section adjacent the second end, said method comprising:
- operating the transmit processing unit so that a first voltage is applied to the track section; and
operating the receive processing unit to detect a first current, and if a parameter of the first current is not within a predetermined range, then communicating with the transmit processing unit so that the transmit processing unit applies a second voltage to the track section, the second voltage having a different magnitude than the first voltage.

Abstract
A method for calibrating a track circuit is provided. The track circuit includes a transmit processing unit, a receive processing unit, and a plurality 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 unit so that a first voltage is applied to the track section, operating the receive processing unit to detect a first current signal, and if a parameter of the first current signal is not within a predetermined acceptable range, then communicating with the transmit processing unit so that the transmit processing unit applies a second voltage to the track section, the second voltage having a different magnitude than the first voltage.
