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 of India, viz. Delhi, Mumbai, Kolkata and Chennai, similar to the Golden Quadrilateral highway system.

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