SAFETY DEVICES FOR TRACK LAID ON CONCRETE OR STEEL SLEEPERS. SUMMARY OF THE STUDIES OF THE COMMITTEE

The present Final Report contains a short survey of the contents of Interim Reports 1-7: RP 1: The electrical resistance of track circuits on tracks with wooden, concrete and steel sleepers as well as ways and means of improving the insulation, June 1957, RP 2: Study of the electrical characteristics of a track circuit, June 1957, RP 3: Methods of computing track circuit, June 1957, RP 4: Questionnaire on the insulating properties of track laid on wooden sleepers, March 1959, RP 5: Axle counters, March 1959, RP 6: Electrical properties of a track laid on wooden sleepers and practical determination of its essential characteristic data, April 1963, RP 7: The electrical insulation of rails on concrete sleepers, October 1963. The second chapter deals with the further development of the technique of insulating means and that of axle counters to the present state. Chapter 3 contains the conclusions obtained from all the studies, more especially those concerning the lower limit of the insulation resistance and the reliability of the axle counters. Finally, a survey is given of those problems recommended for additional research.
