description A rail break or vehicle detection system includes a plurality of voltage sources, each coupled to one of the plurality of zones. A plurality of resistors are provided, each coupled in series with one of the plurality of voltage sources. A plurality of current sensors are provided, each coupled to one of the plurality of resistors and adapted to measure a first set of values and second set of values indicative of current flowing through the resistor. At least one control unit is adapted to receive input from the plurality of current sensors and to compare a difference between the second set of values and the first set of values to a predetermined threshold limit to detect presence of a rail vehicle on the block. The control unit is further adapted to switch a polarity of each voltage source.
