The Metro 12 corridor, which connects Kalyan to Taloja for greater connectivity, has just seen the release of contracts from the Mumbai Metropolitan Region Development Authority (MMRDA). Eknath Shinde, the Chief Minister of Maharashtra, released funds for the project in the amount of Rs. 15210 million and said that construction would soon get underway. The Kalyan-Dombivli-Taloja line is the upcoming addition of Mumbai Metro's Orange Line (Thane-Bhiwandi-Kalyan). This new corridor, which will be 20.75 kilometres long and include 17 stops, would offer a quick and easy way to go to and from the planned Navi Mumbai International Airport. On the 20 kilometers-long line, which will have a total of 17 stations, MMRDA has put out bids for nine stations. The first phase of the contract has a price tag of Rs 7800 million. Depending on demand, MMRDA plans to operate three- or six-coach trains in this region. Citizens of Kalyan-Dombivli, Ambernath, Ulhasnagar, Badlapur Thane, Navi Mumbai, and Panvel will benefit greatly from the line's integration with Mumbai Metro line 5 once it becomes operational. The corridor travels through agricultural and barren land with relatively few people, according to the Detailed Project Report (DPR). According to the DPR, the primary objective of this corridor is to encourage people to relocate from crowded parts of the city to this area and speed up development efforts. By providing an alternative means of commuting, the project also aims to alleviate Mumbai's congestion. Three-car coaches will initially operate services on this route, followed by six-car trains. There will be a total of 15 rakes on the route. By 2031, MMRDA anticipates daily ridership of more than 2.6 lakh and a first-year passenger count of approximately 1.25 lakh.
