They run on the 21.61 km Line-1 of Sarthana (Dream City), and each has three cut and cover stations that have some Box Pushing as well as the New Austrian Tunnelling Method (NATM) for station connectivity.

GMRC had made the invitation for both packages in July 2020, which had an estimation of Rs 929.46 and Rs 942.16 crore, respectively. They had also expected the contractor that won the bid to complete all of the civil work within 40 months after the contracts had been awarded and drawn up.
