SYSTRA MVA Consulting prepared and submitted the project’s feasibility report to K-Rail in May 2019 and its Detailed Project Report with alignment in March 2020.

On April 16 2020, K-Rail’s Board of Directors approved the line’s Detailed Project Report (DPR), with the addition of one new station at Kochi’s Cochin International Airport, and submitted it to the Kerala government for its approval.
