[Machine Translation] There's more! Light Rail Tracks! Murayama-Yamaguchi Reservoir (large-scale civil engineering works), Tokyo Prince's military track, mines, lumber mills, pleasure railroads, and agar factories... This is a continuation of "Ultimate Narrow Gauge Railroads: A Collection of Records of Narrow Gauge Railroads", which revives light railways that have been quietly active in various places. The book is full of never-before-published materials, such as the rolling stock records of Takata Kikou, which ceased manufacturing rolling stock, and the bodies of decommissioned cars lying in quiet rest. Here are "Railroads" you never knew existed.
