AUTOMATIC RAILROAD TRACK INSPECTION
A technical survey of the automated stationary and mobile track test train systems to date is presented. The use and availability of sensors is also reviewed. A method of in-situ excitation in conjunction with a radio interrogation coupled to existing railway communication system is discussed. The automatic inspection system proposed here is limited to the track bed and the rails. The rails are tested for any fissures and flaws and not for the cross-over error and misalignment although these are invariably also caused by the settling of the track bed. The major features of this system are the real-time segment interrogation system and track sensors. The problem of selective random-spacing deployment to cover maximum optimum segment is also discussed. The need for the railroad industry to expand their efforts in the area of development of automatic track and track bed inspection is shown to be highly desirable as well as economical from an operational stand point.
