In order to clarify the three-dimensional structures of the persistent meteor train, thesimultaneous observations of the Leonids trains were carried out in the meteor train observation(METRO) campaign in Japan during 1998-2001. As was predicted by some researchers, theLeonids meteor showers/storm were observed in these four years, and we could detect a lot ofpersistent meteor trains within a few of hours near the each maximum encounter. Through theMETRO campaign, the 36 groups of simultaneous observations were successfully detected includingseveral examples from multiple stations. In this paper, the couples of three-dimensional structuresof the persistent trains in the early stage are analyzed, and the existence of tube structure of thepersistent meteor train was experimentally proved by the high-resolution simultaneous observationsfrom multiple stations.
