Ueno Zoo
The Ueno Zoo Monorail is a long suspended monorail operated by the Tokyo Metropolitan Bureau of Transportation (Toei). It is similar to the Wuppertal Schwebebahn, but has rubber tires rather than steel wheels. The line began operating on December 17, 1958. After 60 years of operation service was suspended on 31 October 2019, with the operator citing the high costs of replacing the aging trains.
