The metro network system serving a populated metropolis usually has a few hours for nighttime stoppage (see Fig. 15), during which all necessary inspection and maintenance tasks shall be done. Our team were allowed to enter the site within 1:30 am to 3:30 am (see Fig. 16), and actually 1.5 hours was needed to accomplish the fieldwork mission there. In total, we spent less than 5 hours and came up with the final results. Parts of the results were selected below for the study. Interested parties may contact us for more details.
