The 32.32 km (20.08 mi) line is planned to be fully elevated, and is expected to consist of 32 stations from Wadala (Mumbai) to Kasarvadavali (Ghodbunder road, Thane) via Chembur, Bhandup Mulund and Teen Hath Naka, a popular traffic crossing in Thane. It is estimated to cost ₹14,549 crore. Its construction was expected to begin by June 2018.
It is expected to be completed in 2025 and provide interconnectivity among the existing Eastern Express Highway at Chembur, Central Railway, Mono Rail, the ongoing Metro Line 2B (D N Nagar to Mandale) at Chembur, and the proposed Metro Line 5 (Thane to Kalyan) at Kapurbawdi, Metro Line 6 (Swami Samarth Nagar to Vikhroli) in Kanjurmarg and Metro Line 11 (Wadala to CSMT) in Wadala. It will provide rail based access to the commercial, government bodies and geographical landmarks in Mumbai. Dedicated depots are planned in Owale land in up to an extent of 20 ha. and in Godrej Land in up to 15.50 ha. area. It will reduce the current travel time by between 50% and 75% depending on road conditions. Alstom awarded to provide rolling stock for this line, but the contract has been cancelled in March 2022 due to delays and uncertainties of the project.
