A method and device capable of reliable and accurate train prediction determinations that account for, and overcome the problems associated with, changing ballast conditions. The method and device will detect the presence of a train in an approach area based on a rail characteristic measured in relation to a first measurement frequency transmitted along the rails. If there is a condition such as a ballast condition that may affect the rail characteristic, the method and device will detect the distance and speed of the train based on a rail characteristic measured in relation to a second measurement frequency transmitted along the rails. Otherwise, the distance and speed of the train will be determined based on the rail characteristic measured in relation to the first measurement frequency.
