Phase-1 of Thane-Wadala Metro Line-4 to open by December

The Phase-1 of the Thane-Wadala route between Gaimukh and Cadbury Junction stations will open in two stages, by December 2025 and April 2026. This is the first time that a Metro corridor will be opening without a car shed. 

Gaimukh station has pit lines for maintenance and stabling lines for parking trains. Two Metro trains from Yellow Line-2 have been transported up on the corridor for trials. The corridor’s own trains are being manufactured by a joint venture of Alstom and L&T.

The priority section inspected in Phase-1 spans 4.4 km and covers four stations — Gaimukh, Govaniwada, Kasarvadavali, and Vijay Garden, which opens in December 2025. The complete section of phase one till Cadbury Junction will open by April 2026.

“The inspection assessed whether all systems are ready in line with requirements of the Commissioner of Metro Rail Safety (CMRS). The viaduct, tracks, and overhead equipment (OHE) are fully completed. Data collection for load calculation and software configuration was undertaken, while the integration of all systems necessary for safe operations was also verified. An Independent Safety Assessor (ISA) certification process will follow, after which CMRS approval will be sought. Only upon securing all statutory clearances will this corridor be opened to passengers,” an official said.

“It is a truly historic moment for Thane today. For the first time, the city is getting its own metro, which is a matter of pride for every citizen. This marks the beginning of India’s longest elevated metro corridor – 58 km, which will connect Wadala to CSMT in the south and extend to Mira Road in the north,” said the official. 

“It will create new connectivity, new economic opportunities, and jobs across the MMR. I wholeheartedly congratulate MMRDA for their efforts in driving this project forward. With a 35 km length and 32 stations, once fully operational, more than 1.34 million passengers will benefit daily. It will save 50–75% travel time, decongest roads, and provide citizens with safe, eco-friendly, and comfortable transport,” the official added.

MMRDA Metropolitan Commissioner Dr Sanjay Mukherjee said, “For Thane, this project is not merely a commuting solution but a new era of social and economic progress. With the Mogharpada depot, four metro lines will be operated in an integrated manner, enhancing overall efficiency. After securing all statutory approvals, MMRDA will open this corridor soon for Thane and Mumbai. This metro line represents a historic transformation in Thane’s transport system.”
