The work is advancing swiftly on the Aqua Line (Line 3) of the Mumbai Metro. In a recent development, the Research Design and Standards Organisation (RDSO) has wrapped up the testing phase for the rolling stock designed for the Metro 3 line, which runs underground between Aarey and Seepz via BKC. Currently, trials are underway in Phase 1, which extends from Aarey to Bandra-Kurla Complex (BKC).
On 24 June 2024, an update on the official X account of the Mumbai Metro 3 project announced the completion of oscillation trials for the Metro rakes. The Research Design and Standards Organisation (RDSO) will now submit the trial report to the Railway Board and the Commissioner of Metro Rail Safety.Â
Meanwhile, other electrical system tests and integrated testing of the rolling stock with signalling are ongoing. Once these tests are completed, the Commissioner of Metro Rail Safety (CMRS) will be called for the final inspection before commencing the public operations in Phase 1.
Commencing on June 8, the trials were executed at a maximum speed of 95 km/h using both empty and loaded rakes. These oscillation trials are essential as they assess how well the train performs dynamically and maintains stability at different speeds.
A thorough assessment of the dynamic stability of rolling stock, especially at high speeds and on curves, is crucial to minimise the risk of derailments. Additionally, testing includes a detailed analysis of how the rolling stock interacts with the track, specifically evaluating the forces applied on the rails. Through these tests, RDSO ensures compliance with safety standards to prevent accidents and ensure passenger safety.
Mumbai Metro Line 3
Mumbai Metro’s Aqua Line (Line-3), spans 33.5 kilometres and serves as a crucial north-south corridor, designed to streamline connectivity throughout Mumbai. It will link six commercial suburbs, 30 office areas, 12 educational institutions, 11 major hospitals, and 10 transport hubs, including both of Mumbai’s airports. Once operational, this corridor is expected to alleviate congestion on roads. The operations for Phase I of the Mumbai Metro Line 3 are anticipated to commence by the end of 2024.
