Mumbai Metro: Green Signal For Oscillation Trials On Line-2A And Line-7, Commercial Run Scheduled To Begin In January 2023

The Research, Design and Standards Organisation (RDSO) has approved oscillation tests for the Phase-2A and Phase-7 metro lines in Mumbai.

This move has enabled the Mumbai Metropolitan Region Development Authority (MMRDA) to invite the Commissioner of Metro Rail Safety (CMRS) to inspect lines that are scheduled to begin in January 2023.

Before approving the commencement of passenger service, the CMRS inspector examines signalling electrical systems and civil works.

The Mumbai Metro Line-2A connects Dahisar to DN Nagar, while Line-7 connects Dahisar East to Andheri East. Both lines have a total length of 35 kilometres, with only a 20-kilometre stretch between Aarey and Dhanukarwadi. 

Metropolitan Commissioner S V R Srinivas said, “We have received the provisional certificate for oscillation trials from RDSO and will soon begin the process for various International safety certifications after which CMRS will be invited for inspection of the lines," reports Times Of India.

RDSO is the sole research and development organisation under the Ministry of Railways. It functions as the technical adviser to Railway Board Zonal Railways and production units.

MMRDA intends to use 28 rakes to conduct service on lines 7 and 2A.

Upon completion, Metro lines 2A and 7 are expected to carry 11.37 lakh passengers per day by 2031, according to the MMRDA.

The Prime Minister laid the foundation stone for both projects in October 2015, costing Rs 12,618 crore.

Mumbai Metro Line 2A (Dahisar-DN Nagar)

Metro Line-2A from Dahisar to DN Nagar is an 18.6 km long, elevated corridor with 17 stations.

It will connect to Metro Line-1 (Ghatkopar to Versova), the existing Metro Lines 2B (DN Nagar to Mandale) and 7 (Andheri East to Dahisar East), and Metro Line 6 (Swami Samarth Nagar to Vikhroli).

The maintenance depot was built on 16.40 hectares of land in Charkop/Malwani for train stabling.

This project will help to alleviate traffic congestion on one of Mumbai's busiest routes (New Link Road) from Dahisar (E) to DN Nagar.

It will allow for seamless and efficient interchange with the suburban rail system and the MRT system at Dahisar and DN Nagar. This project will connect the Western, Central, and Northern Suburban Mumbai areas.

Mumbai Metro Line 7 (Andheri East-Dahisar East)

Metro Line-7 runs 16.5 kilometres from Andheri (E) to Dahisar (E) and has 13 stations.

The project will connect the existing Western Express Highway, Metro Line-1 (Ghatkopar to Versova), Metro Line 2A (Dahisar to DN Nagar), and Metro Line 6 (Dahisar to DN Nagar) (Swami Samarth Nagar to Vikhroli).

It will allow for seamless and efficient interchange with the suburban rail system and the MRT system at Andheri, JVLR and Dahisar.

Metro Line-7 will connect Central Mumbai to the northern suburbs of Mumbai. It will provide rail access to the Mumbai international airport, the SEEPZ, the National Park, and other commercial and geographic landmarks.

Depending on road conditions, it should reduce current travel time by 50 per cent to 75 per cent.
