4)Railways didn't ever make profit then how can someone think of modernising it.
5)If china can connect tibet with mainland china so connecting all four dhams isn't such a big deal..
6)China recently connected Germany and Iran with main land china with rail network so laying tracks upto at least france isnt such a big deal..Because rail network is present in almost all the countries what one needs to do is to make all the tracks in each country of same guage..
