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, since in IR both government and private players will run trains, so leaving Controlling in the hands of private players with destroy the balance between govt trains and different private companies and also will create chaos. Also, politics is also involved in IR so leaving Controlling in the hands of private players will have regional political influences also more.
I still believe, running private trains in India is...
more... never going to be a profitable. 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. Airlines are favoured by people because travel time is very less compared to trains, but this will not happen in trains. It is i believe a poor strategy by government. I think those private players who have opted out of this pkg has done a clever job.
In India you cannot maintain 160kmph end-to-end because of its geography, culture and habits which vary from one place to another and also population is higher here.
