Trials for Line-2A and Line-7 of the Mumbai metro, which kicked off back in September this year, have finally concluded. With this, the Research, Design and Standards Organisation (RDSO) has approved the test results for the high-speed oscillations trials on both lines.

As part of this, the Mumbai Metropolitan Region Development Authority (MMRDA) has invited the Commissioner of Metro Rail Safety (CMRS) to examine the electrical signalling systems. Following the tests, MMRDA has also scheduled commercial metro operations on both lines from January 2023.

The high-speed oscillation trials include a cluster of high priority tests conducted by RDSO. Checks relating to maintenance of tracks, bridges, signaling, OHE and allied assets are carried out during these trials.

RDSO is India's sole R&D department under the Ministry of Railways which operates as the technical adviser to Railway Board Zonal Railways and production units.

Providing access to some of the most significant areas such as Mumbai Airports, Sanjay Gandhi National Park and SEEPZ, Line 7 of Mumbai Metro stretches across a length of 16.5 kilometres. The line also connects the Central Mumbai area to the suburban regions of town.

On the other hand Line 2A extends over an area of 18.6 kms and connects Dahisar to DN Nagar. Furthermore, it also connects many existing metro lines for a seamless exchange of trains on different lines.

MMRDA has projected that Metro lines 2A and 7 will carry 11.37 lakh passengers per day by 2031, and aim to provide ease of commute between various points of the metropolis.
