RUNNING TEST FOR THE STUDY OF COMPOSITION BRAKE BLOCKS

The study of composition brake blocks has been advanced in JNR to obtain better brake efficiency for the operation of high speed train. As a part of its study a car running test at Sanyo line (the rail condition is straight and flat) was carried out using the composition brake blocks specially made for trial. Since a part of the brake equipment was provisional in this test, brake cylinder pressure rose slowly and idling time was 0.7 to 1.2 sec longer than usual. If it is possible to shorten the idling time by any brake equipment up to that of the emergency brake, the brake distance will be shortened within 600 m at the initial brake speed 120 km/h. In this case the variance of brake distance may be involved in it.
