* To achieve full benefits of and to make privatisation feasible , a complete package needs to be given to private companies including laying of rail routes/stations, operating trains, marketing of trains, development of commercial spaces in and around stations, development of smart colonies/cities along the rail route.
* Again above is practically very difficult, the biggest hurdle being land acquisition.
