Osaka: Metro Station Instrument Shelters Set for Removal; Devices Measured Temperature, Humidity for 90 Years

OSAKA — Osaka Metro Co. will remove all the instrument shelters, which are installed at its station platforms to measure temperature and humidity, by early March. Their white triangular roofs have been familiar to passengers, but they have been used less and less in recent years, with their more than 90-year history soon coming to an end.
