Abstract:

A workable detection system is designed to record sabotage activity on a one-mile section of railroad and discriminate against noise in the rail and pedestrian traffic. Elimination of false alarms and conservation of power in an RF data link at important considerations. The four features of discrimination logic are frequency filtering, amplitude threshold, pulse repetition rate, and aural monitoring. Preliminary conclusions and recommendations in First Interim Technical Report are reviewed and substantiated with specific data and appropriate changes in details. Field experiments were conducted on railroads with 5- and 6-in. rails. Electromechanical instrumentation capable of detecting seismic and acoustic waves was utilized. A third method of detection was the subject of a classified report submitted separately with First Interim Technical Report.
