Train trials will begin on a 10.5-km stretch that contains a total of ten stations on the Wadala-Thane Green Lines 4 and 4A in August.

While the Green Line 4 - from Wadala to Kasarvadavli - is a 32.32-km elevated corridor in the eastern suburbs with 30 stations, Line 4A is its 2.7-km extension from Kasarvadavli to Gaimukh, which comprises two stations and is nearly complete.

The trials, which include the alignments of Line 4 and 4A, will be undertaken from Cadbury Junction to Gaimukh, and apart from these stations include those of Majiwada, Kapurbawadi, Manpada, Tikuji-Ni-Wadi, Dongripada, Vijay Garden, Kasarvadavli and Gownipada.

Work on Mumbai Metro projects has been proceeding at a steady pace over the past few years, and the project is now in the delivery phase. On April 16, 2025, trial runs began on the 5.5-km Diamond Garden-Mandale stretch of Mumbai Metro Line 2B; on May 9, the underground Aqua Line 3 was extended between BKC and Worli; and on May 14, the train trial run of Phase 1 of Red Line 9 commenced, marking Metro connectivity between Mumbai and Thane districts. While the entire Red Line 9 has eight stations, including Dahisar, Pandurang Wadi, Miragaon, Kashigaon, Sai Baba Nagar, Meditiya Nagar, Shahid Bhagat Singh Garden and Subhash Chandra Bose Stadium, in the first phase, the first four stations till Kashigaon will be functional.

Pitline

Since the car shed of this line is not ready, the Metro team has worked out a "pit line" beyond the terminal station where trains can be parked and maintained. This will be a temporary arrangement till the depot at Mogharpada for this line is ready. A pit line is a railway track with a depression or pit along its length, allowing for access to the underside of trains for cleaning, inspection, and maintenance.

Back on track

"Since Dr Sanjay Mukherjee took charge as Metropolitan Commissioner, MMRDA has taken focused steps to eliminate hurdles that had stalled several Metro projects across the Mumbai Metropolitan Region. Many of these delays were due to land-related and implementation challenges. Under his leadership, MMRDA has systematically resolved these issues to bring projects back on track. The approach is clear: ensure that completed stretches are made operational without waiting for the entire corridor to be ready," an official said.
