BTW, my love for Chinese (mountain) railways started with an article in the March 1988 issue of National Geographic. I dug it out over the weekend because I remembered that the author also travelled on the Chengdu–Kunming line. I found the locations of two of the best photos on Google Maps, and it's quite impressive how the landscapes changed in 20-25 years (double-tracking & electrification, orderly level crossing & throngs of bikers gone, modern urban sprawl making its appearance, several new bridges nearby).
