The first set of four coaches for the Colaba-Bandra-Seepz Metro-3 corridor arrived in the city on Tuesday. The cars will be used for trial runs on a 3-km tunnel stretch between the temporary facility of Sariput Nagar and Marol Naka station.

The Mumbai Metro Rail Corporation Limited, the project implementing body, expects to complete the car depot work and start commercial operations of Phase-I—between Seepz and BKC—in the first quarter of 2024. Christened as Aqua Line, the colour scheme of Metro-3 is inspired by the sea, an integral part of Mumbai.
