Systems and methods that can be used in a Positive Train Control system to continuously monitor train integrity and end of train location using radio frequency (RF) ranging techniques to determine the line of sight distance between the head end and the end of the train. The systems and methods allow PTC controlled trains to maintain positive length of train awareness and to determine if a portion of the train separates unintentionally. The systems and methods can be implemented on existing RF infrastructure used on trains, without impacting existing messaging traffic, adding bandwidth or power requirements. The systems and methods work on stretched trains running on tangent or straight track, as well as on foreshortened trains running on curved track.
