Abstract
The present disclosure is directed to a dragger. The dragger may have a plurality of sensors configured to be located adjacent a railroad track. Each of the plurality of sensors may be oriented at an angle relative to a horizontal plane. The dragger may also have a controller in communication with the plurality of sensors. The controller may be configured to receive signals from the plurality of sensors, determine a parameter based on at least one of the received signals, and detect a fault condition when the parameter exceeds a threshold.
