When you put in a transit line, the surrounding land values go up -- it's as old as the railroads. The governing body needs to capture the increase in those land values. This is how transit is funded in many Asian countries -- the transit project goes from being a cost boondoggle to a profit center that pays for itself, either by taxing the uplift in land values, or the governing body owning that land and leasing it out to e.g. shops.
