if FDI is allowed over Passenger sector or say IR as a whole then foreign companies will only invest to enhance their profitability & thus will have a severe impact on fare structure.For eg,we've Konkan Rly which was established long back but not by the Govt but some external agencies...As a result till date,the distance over KR are 40-50% inflated so passengers are paying 40-50% enhanced fare than what they should be paying for.Had it been solely Indian Rlys,the inflated part would cease to apply as soon as the cost of construction is over(for eg,Saraighat Setu in Assam).but as a private firm,whoever has participated in construction has acted such as a way of investment tool & not to serve the people of the country in general.
