Fantastic 3D model of the disused facilities. I visited a lot of disused railway lines back in UK (England) when I was there for University, by following satellite pictures and old maps. It was extremely fun, feels so good to imagine there were busy traffics going through the lines. Respect from China, subbed and please keep going. As a Chinese native speaker I barely understand your subtitles lol, that's why I clicked your video
I don't even know what language this is nevermind being able to read it, but the visual presentation alone is so well done I completely understand we're tracking the ghost of a railway line born in 1931 and torn out in 1964. Excellent, excellent job. Kudos.
