The 10.5-km Gaimukh–Cadbury Junction section of Mumbai Metro Line 4 and Metro 4A has received certification from the Research Design and Standards Organisation (RDSO), bringing the project a step closer to commercial operations.
The certification follows over six months of trial runs and technical assessments conducted by the Mumbai Metropolitan Region Development Authority (MMRDA). With the RDSO approval in place, the authority will now seek the final safety clearance from the Commissioner of Metro Rail Safety (CMRS), a mandatory requirement before passenger services can begin.
The Gaimukh–Cadbury Junction corridor is part of the larger Metro Line 4 project connecting Wadala to Kasarvadavali via Thane. Once operational, the route is expected to ease traffic congestion and significantly improve public transport connectivity between Mumbai and Thane.
MMRDA officials said an application for CMRS inspection will be submitted shortly. Passenger services on the stretch are expected to commence after the safety regulator completes its inspection and grants approval.
The development marks a significant milestone for one of the Mumbai Metropolitan Region's key metro projects, which has faced delays in recent years but is now moving closer to opening its first operational section.
