High-level atmospheric pressure fluctuation is observed in a narrow gauge JR Ltd. Exp. EMU, when the train rushes into a long signal track tunnel. The authors previously reported at the past joint symposium conferences on the behavior of the pressure fluctuation, which was measured and recorded in the event recorder installed on the JR Ltd Exp. In the course of the investigations, the authors found there were many differences between the fluctuations measured on the up-train and the ones measured on down-train, even if the date were recorded at the same position. To investigate the detail of the differences, a couple of atmospheric pressure sensor were attached on the train, one sensor was put in the head-end car, and another sensor was put in the rear-end. These sensors can accurately record the pressure fluctuation with very short sampling time. The datum measured at the head-end is radioed to the event recorder, installed in the rear-end car. Thus, both of atmospheric pressures in the head-end and rear-end were simultaneously measured. The results are written in the paper.
