DFC is the most path breaking advancement which has been excluded from the race.
Another major development which is underway and may turn out to be a path breaking is HST project Mumbai-Ahm. If handled and implemented properly, this project may change the way Indians travel in future.

connected to HSTs shall become backyards of Metros like Mumbai, Delhi etc. These cities shall take some load and help in decongestion of these Metros. In general, cities connected/ regions served by the HSTs shall witness fast development in economic activities, as has been experience in China.
But every thing depends on, how better this most note worthy and hi-profile project is implemented. High level of indigenisation /safety, innovative ways to restrict the cost of project and keep the fares low is key to its success.
This project is very important if India want to graduate from a developing nation into the category of developed nations, much like the way China is doing.
Success of this project shall open the doors to diamond quadrilateral of HST network with some spurs to connect important cites not falling in Golden quadrilateral.
