Many experiments have been made to clear the true state of adhesion coefficient μ which significantly affects the performance of rolling stock. However, such experiments have been made mainly in laboratory rooms, and the experiments made on main lines have been simply a medley of data only at the spot of wheel slipping. The author employed a "Slipping adhesion test truck" built on a new idea of realizing the measurement of μ continually while running, and observed the true state of μ along the mainlines. From the results thus obtained, the author derived the statistically processed μ, and analyzed the relation between μ and the rate of wheel slipping. In addition, the author referred to the various factors that reduced the value of μ.
