Hyperloop train might be coming to India

The biggest problem is that there must be only one train on one tube.
It means if it takes 25 mins from Mumbai to Pune, the maximum frequency of the hyperloop train is one per 50 mins.
So, under this system, we cannot increase train frequency unless adding tracks along the whole section.
So, the system will end up with attraction in playground, without breakthrough.
