To be clear, the 'luxury' flats which get put up around new stations, have their value significantly increased by the huge public investment in that new infrastructure. A small amount of that increased value is levied against the cost of the infrastructure and it's spun as property development subsidising new transport links. This is backward logic. What is really happening here is that huge amounts of public money are being used to subsidise these developments. The question you need to ask is, would this station be put here without the new development? If not, then it is the station serving the development, not the development serving the station. Existing communities and taxpayers are largely ignored when it comes to transport investment, whilst developers interests are central. The flats of course, are mostly marketed to overseas investors.
