DERIVATION OF INITIAL SPEEDS AND STOPPING DISTANCES FROM DECELERATION/TIME CURVES

Brake testing involves the measurement of deceleration. This can be obtained by direct means or by calculation knowing the initial speed, stopping distance, and stopping time. The method to be described involving the use of a recording decelerometer and stopwatch only gives a full assessment of the braking performance, and since no electrical or mechanical connection with the test vehicle is required has the obvious advantage of permitting tests on any brake at any time without previous preparation. Success of the method has been proved over a number of train tests where independent measurements of speed and distance have been available.
