In mid-2017, Ineco, along with its other partners in the consortium it leads, submitted the final report of the feasibility study on the high-speed line between New Delhi and Calcutta to the authorities of the state-owned company High Speed Rail Corporation of India (HSRC), after two years of work.
The study includes: demand studies; preliminary analysis of alternative routes; calculation of travel times; selection of railway technology to be implemented (gauge, superstructure, electrification, security and communications facilities, etc.); necessary singular works; rehabilitation and resettlement of the populated areas concerned; environmental analysis; rolling stock and operation and maintenance.
It also conducted an economic-financial study to determine the viability of the new line, as well as the most appropriate financing method.
The project is part of the so-called Diamond Quadrilateral Programme, an ambitious high-speed rail development programme in India that the new government launched in the summer of 2015. It is a diamond formed by the cities of New Delhi, Calcutta, Bombay and Chennai, which are more than 1,000 kilometres apart.
