• We have been conducted the meteor train observation (METRO) campaign in Japansince 1998, and fruitful observations were collected from many amateur observers during 1998-2001.The purpose of the METRO campaign is to detect many train images from multiple stations andto investigate their height distribution, three-dimensional forms, and detailed structures. We havecalled for the popular photographic observations of the persistent meteor trains with the optimumcondition. We obtained 5 examples in first three years. And in 2001, the Leonids meteor storm wasobserved over East Asia as was predicted by some researchers, so that the observers in Japan couldfortunately encounter lots of bright fireballs with meteor trains within a few hours, resulting inthe 242 sequence images for the 134 independent persistent trains. It was the first vast-amount-ofobservation of the persistent train over 100 detections in one night. There were confirmed the 36simultaneously observed meteor trains as well as the 98 examples detected from single site. In thispaper, we present the method of the METRO campaign and its evolution during the four years.
