The Diamond Quadrilateral is a project of the Indian railways to establish a high speed rail network in India. The Diamond Quadrilateral will connect the four mega cities in India, Delhi, Mumbai, Kolkata and Chennai, similar to the Golden Quadrilateral expressway system.

High-speed train on Mumbai-Ahmedabad section will be the first high-speed train corridor to be implemented in the country. On 9 June 2014, the President of India Pranab Mukherjee, officially mentioned that the Government led by Prime Minister Narendra Modi will launch a Diamond Quadrilateral project of high speed trains.[1]

History

Prior to the 2014 general election, the two major national parties (Bharatiya Janata Party and Indian National Congress) pledged to introduce high-speed rail. The INC pledged to connect all of India's million-plus cities by high-speed rail,[2] whereas BJP, which won the election, promised to build the "Diamond Quadrilateral" project, which would connect the cities of Chennai, Delhi, Kolkata, and Mumbai via high-speed rail.[3] This project was approved as a priority for the new government in the incoming president's speech.[4] Construction of one kilometer of high speed railway track will cost ₹100 crore (US$14 million) - ₹140 crore (US$20 million) which is 10-14 times higher than the cost of construction of standard railway.[5]

India's Union Council of Ministers passed the proposal of Japan to build India's first high-speed railway on 10 December 2015.[6] The planned rail will run approximately 500 km (310 mi) between Mumbai and the western city of Ahmedabad at a top speed of 320 km/h (200 mph).[7][8] Under this proposal, the construction began in 2017 and is expected to be completed in the year 2022.[9] The estimated cost of this project is ₹980 billion (US$14 billion) and is financed by a low-interest loan from Japan.[10] Operation is officially targeted to begin in 2023, but India has announced intentions to attempt to bring the line into operation one year earlier.[11] It will transport the passengers from Ahmedabad to Mumbai in just 3 hours and its ticket fare will be cheaper than air planes i.e. ₹2500-₹3000.

Current status

Contracts have been awarded to carry out the feasibility study of high speed rail corridors. The corridors being considered for feasibility study are as follows,

  1. Package 1: Delhi Mumbai - Feasibility Study Contract awarded to a Consortium of M/s The Third Railway Survey and Design Institute Group Corporation (CHINA) and Lahmeyer International (India) Pvt. Ltd, a
  2. Package 2: Mumbai Chennai - Feasibility Study Contract awarded to a Consortium of M/s SYSTRA (FRANCE) - RITES- Ernest &Young LLP
  3. Package 3: Delhi Kolkata - Feasibility Study Contract awarded to a Consortium of M/s INECO (SPAIN) - M/s TYPSA- M/s Intercontinental Consultants and Technocrats Private Limited. Expected cost of 1583 km Delhi - Kolkata corridor is around ₨ 84000 crores and is capable of reducing the travel time to just over 5 hrs from existing 17 hrs taken by Rajdhani.[12]

The Ministry of Railways stated that the final feasibility reports for three high speed rail lines — from Mumbai to Chennai, Delhi and Nagpur - would be completed by January 2017. Preliminary geo-technical studies, and other related studies, are expected to begin by 2018.[13]
