You think a small town in China could possibly ever say no to Beijing? Would a tiny community in an American city in the 40s or 50s be able to stand up to an interstate highway project? Absolutely not, but these small towns along the rail route have been screwing over this project for years to score cheap votes from an ignorant electorate. That's the political climate we live in now, same reason why SB50 has been tabled until 2020, NIMBYs (who unfortunately vote very reliably) plugging their ears and ignoring solutions to the inevitable. It has to work eventually, airports are a huge source of pollution and resulting health problems.
