Mumbai's fast-evolving metro network is gearing up for another major milestone. After the recent successful trial runs launched on Metro Lines 2B and 9, on partial stretch the Mumbai Metropolitan Region Development Authority (MMRDA) is now preparing to launch trial operations on a key stretch of Metro Lines 4 and 4A—paving the way for greater connectivity across the city's eastern corridor.
The buzz is building around a 10-kilometre stretch that spans 10 stations from Cadbury to Gaimukh Metro Lines 4, 4A alignment, with sources suggesting that trial runs could begin soon. These stations include Cadbury, Majiwada, Kapurbawadi, Manpada, Tikuji Ni Wadi, Dongripada, Vijay Garden, Kasarvadavli, Gownipada, and Gaimukh—each representing a vital link in a transit line that could drastically reduce travel time for thousands of commuters.

Metro Line 4, stretching 32.32 kilometers from Wadala to Kasarvadavali, is entirely elevated and includes 30 stations. Once completed, it will become a backbone of east Mumbai’s transit system. It’s designed to seamlessly connect with other critical transport arteries such as the Eastern Express Highway, the Central Railway, Mono Rail, and future Metro lines including 2B, 5, and 6. The aim is to slash commute times by 50% to 75%—a game-changer for those currently stuck in Mumbai’s gridlocked traffic.

Meanwhile, Metro Line 4A a 2.7-kilometre extension from Kasarvadavali to Gaimukh of Metro 4, with two stations adding further depth to the metro's reach into the Thane region.

By targeting to launch trials on Line 4 and 4A, the MMRDA is not just expanding infrastructure—it is redefining the way Mumbai moves. With every new stretch tested and readied, the dream of a faster, more connected city inches closer to reality, the source emphasised.
