STUDY OF THE PROBLEM OF ADHESION OF LOCOMOTIVES FROM THE POINT OF VIEW OF THEIR CONSTRUCTION AND OPERATION. THE DEVELOPMENT OF SPARK CLEANING FOR IMPROVING LOCOMOTIVE ADHESION
This report contains a description of the test carried out between Landres and Audun-le-Roman in France with the spark cleaning equipment developed by the Battelle Institute in conjunction with the SNCF and ORE. Slip risk curves were plotted for starting tests on an electric locomotive and at 5, 10, 15 and 20 km/hr. The results show that with the existing circuits the improvement in adhesion is negligible at 20 km/hr but appreciable on starting. They indicate that number of electrodes is insufficient to have much effect. that is to say the most polluted stretches of line are effectively cleaned when starting but at higher speed the number of electrodes is insufficient to have much effect. The second part of the report describes the circuits used and how they have been evolved. The effect of the sparking on the mechanical properties of the rail and on television reception will be the subject of further study.
