<b>Abstract: </b><br> The concept of customer satisfaction requires a good service to the customers, whatever for pre-traveling, on-traveling and pascatraveling In case of `on-traveling process', the safety factor and the confortable of traveling are very important factors for determine the riding quality (running quality) of the vehicles (coaches or wagons).<p> Safetyness and confortable level of the rail vehicle can be determined by measure the running quality. There are several metodes have known for measuring the running quality. In this tesis, we use a metode named Janeway metode, that processed by a simple and familier software (AutoCad, Excel and A atLab). The acceleration data (analog) proper to the rail vehicle (in this case, we use the wagon/KKBW) taken from out put of the accelerometer, in time domain transformed to discrete data and then we transform it to frequency domain with FFT process. The first, we have to do sampling process with the analog data (with AutoCad program), we make the array of this descrete data with Excel, and then we do FFT process (with MatLab program) for transform it to frequency domain./p> With The Janeway metode we can see the vibration acceleration pattern (amplitode variation) in frequency domain for each difference speed. We also can see the impulse of the acceleration, how big is this and at what frequencies it happened.<p> The output of this process shows us, such in what class and category is that coach or wagon. At the end it should he a good input or feed back for maintenance, operation and redesign the vehicle for the future.
