The 245-km corridor project will be the first semi-high speed venture of the Railways with French aid which would enable some trains to run at a maximum speed of 200 kmph.
"SNCF, France's state-owned rail company, started the study in January 2016 and submitted the final report today," Railway spokesperson Anil Saxena said.
The study was under the consideration of the railway board, he told PTI.
Sources said that in its over 1500-page report, the company stated that the upgrading of the route would cost more than Rs 10,000 crore. The figure, however, could not be confirmed officially.
The project is expected to be launched in January 2018 when French President Emmanuel Macron is likely to visit India, officials said.
The Railways plans to upgrade 4000 kilometres of networks across seven routes, which include Mumbai-Goa, Chennai- Hyderabad, Mysuru-Chennai and Delhi-Kanpur.
