This report presents some illustrations on practical use of the car-vibration analyzing system developed for the maintenance of riding quality. This analyzing system was applied experimentally to the long-term endurance test of Shinkansen test of Shinkansen electric cars at the speed of 240 km/h. As a result, it was confirmed that this system was available for practical sue both in research work and maintenance. Further, the following matters were made clear. (1) Riding quality level L_T on the Tohoku Shinkansen at 240 km/h speeds is evaluated to be in the range of "Good". (2) The riding quality of each car of a train varies by the coupled position in the train. (3) The L_T of vertical vibration does not increase with the extension of running distance. (4) The L_T of lateral vibration increase 2〜3 dB in the running distance of 300000 km until truck overhauling.
