Because of security reasons and also to maintain the whole railway setup, Controlling needs to be kept in the hands of Indian Railways, because private players ftom India as well as Global are involved in this package, so u cannot leave Controlling in the hands of private players.

Also, politics is also involved in IR so leaving Controlling in the hands of private players will have regional political influences also more.

A country where a huge population is middle class and below middle class, how can a costly private train travel with travel time just few hours lesser than Govt runned trains can be profitable.
