Indian Railways has come up with a Vision 2020 document. It is at

In that it says:

The Vision 2020 also envisages the implementation of at least 4 high-speed rail projects to provide bullet train services at 250-350 kmph, one in each of the regions of the nation and planning for at least 8 more corridors connecting commercial, tourist and pilgrimage hubs. Six corridors have already been identified for technical studies on setting up of High Speed Rail Corridors. These are:
i. Delhi-Chandigarh-Amritsar;
ii. Pune-Mumbai-Ahmedabad;
iii. Hyderabad-Dornakal-Vijayawada-Chennai;
iv. Howrah-Haldia;
v. Chennai-Bangalore-Coimbatore-Ernakulam;
vi. Delhi-Agra-Lucknow-Varanasi-Patna

In the following map the above six corridors are shown in RED. In BLUE are the corridors that I think Orissa government should push for on the ground of connecting to the commercial, tourist and pilgrimage hub of Bhubaneswar-Puri. These two corridors are:

  • Kolkata-Bhubaneswar-Puri and
  • Bhubaneswar-Visakhapatnam-Vijaywada

In addition the following corridors (shown in GREEN) should also be made to connect the smaller corridors to make larger corridors.

  • Hyderabad-Pune
  • Ahmedabad-Jaipur-Delhi
  • Patna-Kolkata
  • Patna-Guwahati
