Besides the Mumbai-Ahmedabad bullet train, other such projects are also underway for which an initial budgetary allowance of INR 100 crores has been proposed for development of infrastructure. The proposed routes for bullet trains will include Delhi-Agra, Delhi-Chandigarh, Mysore-Bangalore-Chennai, Mumbai-Goa and Hyderabad-Secunderabad.
Prime Minister Narendra Modi plans a Diamond Quadrilateral connecting the four metros with high speed bullet trains which will have a speed of between 160 to 200 kmph. The Maharashtra government is keen that the bullet train line passes through Belapur so as to include Navi Mumbai in its realm, though railway officials are of the opinion that this detour should be avoided.
The same situation exists in Ahmedabad as to where the terminal should be with railways opining that it should be a little away from Ahmedabad station. The line was also originally expected to start from Pune which was later dropped as laying of high speed network across mountainous terrain on the route would have involved extensive expenditure.
As of now, it is estimated that the overall cost would be about Rs 60,000 crores for the project. The train will travel at a speed of up to 350 kmph. Once operational, instead of the existing 9 hours, the distance between Ahmedabad and Mumbai will be covered in 3-4 hours.
