Abstract
A broken rail detection system including: a power module having: a first electrical connection to the first rail to apply a direct current voltage; and a second electrical connection to the second rail to apply a direct current voltage; a diode shunt arrangement; a measurement device to sense or measure current; and a controller programmed or configured to: (i) cause at least one application of a direct current voltage of a first polarity on the railway track; (ii) determine the current resulting from the application step (i); (iii) cause at least one application of a direct current voltage of a second polarity on the railway track; (iv) determine the current resulting from the application step (iii); and (v) determine the presence or absence of a break based at least partially on the determined current.
