Line 4 nearly operational

I know I've been critical in the past about Beijing's subway having too many "unnecessary" stations, but Line 4 may have just the opposite problem -- too many all-too-necessary stations, making for crowded trains. Anyway, it's long overdue, as anyone who's tried going to Peking University and Tsinghua, or the zoo market (or the zoo itself) or the park Yuanmingyuan or Nanluoguxiang knows quite well. And now that it's so tantalizingly close to opening, I'm all too willing to overlook the fact that it makes an unnecessary stop at Lingjing Hutong (apologies to the subway company, as I've learned that the renovations in my old neighborhood were probably unrelated to subway construction).

Now go watch this video about Line 4.
