A method and system for determining rail defects. The method and system receive route performance measurements from a vehicle system traveling along a route and normalize the route performance measurements based on one or more characteristics of the vehicle system. The method and a system also determine a defect for a segment of the route based at least in part on the normalized route performance measurements with respect to a threshold bandwidth corresponding to the segment. The method and system also examine velocity differences in a vehicle speed of a vehicle and the angular speed of the axles and/or wheels of the vehicle system traveling along a route to determine if the route is damaged and/or to identify the location of the potentially damaged section of the route. The differences may represent wheel creeps of the vehicle system.

A system is provided for sensing misalignment of a railroad signaling system. The railroad signaling system includes at least one railroad signal coupled to at least one elongated member adjacent to a railroad. The system includes at least one transmitter positioned within at least one elongated member, and at least one receiver positioned from each of said at least one transmitter within at least one adjacent elongated member to the at least one elongated member. More particularly, the system includes at least one electronic device coupled to each of a transmitter and each of at least one receiver, to sense detection of each transmitter by at least one receiver of at least one receiver indicative of misalignment of the railroad signaling system.
