High-speed trains to connect top four metro cities in India.
The Indian Railways is busy drawing up a detailed blueprint for the “Golden Quadrilateral” project, which will reduce travel time thanks to high-speed trains that will run at 160 km/h.
The mammoth project entails creating a 10,000-km network of semi-high speed routes linking New Delhi, Mumbai, Chennai and Kolkata.

The project has been cleared by the Niti Aayog and is awaiting Cabinet sanction. An estimated ₹ 36,000 crore will be required for this project, and the board is likely to finalise a detailed cost estimate by 31st December 2017.
A senior Railway Board official told the Asian Age, “We are still finalising the blueprint and efforts are on to officially launch the project by August 2022 to coincide with the celebrations around India’s 75th year of Independence. However, everything depends on how we manage to meet every deadline set for the project.”

The blueprint for the interconnecting line between the four metros — Delhi-Mumbai, Delhi-Howrah, Delhi-Chennai, Chennai-Howrah, Chennai-Mumbai and Howrah-Mumbai — were drawn up on Tuesday.
Currently, the Indian Railways carry over 20 million passengers a day. Regular trains travel at a speed of 88-90 km/h, and these high-speed trains will help distribute passengers and save precious time.
