We have been hearing news about Bullet trains being introduced if XYZ comes to power or so & in the present scenario we have much things to do than constructing these .Instead of wasting crores of rupees in the construction of these bullet trains we can invest on trains which can achieve almost same speeds on the present track conditions in India like the Virgin train in the UK or the AMTRAK in US which can achieve great speeds without changing the infrastructure .It would need slight upgradtion but that would be definitely less as compared to construction of new line
