Brother,
Japan started its first bullet train in 1965.
After 50 years we are still struggling.
Look this Bullet train Project as Investment By Japan. We have to repay loan in 50 years that too 0.1% Interest rate.
If...
more... we don't take this bullet train project, we are not going to get about 90000 crore rupees investment.
You are correct that we should pay more attention to existing track.
But In India we are leaving in 5 different ages. From Super computer era to Stone age. Because we have too much diversity.
As We cannot stop our ISRO satellite program saying that many people has no food to eat, we shall not object bullet train project also.
We have to start simultaneous development in every direction and in every field.
Even 99% cannot afford bullet train than 1% can afford. that means almost 1.25 crore people can afford. That is huge number.
So welcome Bullet train Project. We are already behind in this sector. Almost more than 50 years behind.
