Why doomsday? Already India has over population. It's kind of good in some way. Actually problem with IR is that its building too many unnecessary railway lines and horrible management. Recently FEDL of ADI - Delhi via JP route is a great example, where they are restricting speed and running trains with Diesel inspite of electrification. They are also doing FEDL for lines where barely 4-5 express trains run daily. Naturally to compensate, it will add more ACs, increase fares. etc
