The Mumbai Metropolitan Region Development Authority (MMRDA) has completed overhead line electrification work on the 20 kilometre trial run section between Charkop depot and Aarey station on metro line 2A (Dahisar to DN Nagar) and 7 (Dahisar East to Andheri East) today. With this, the trial run on the said stretch will begin from May 31st onwards. The MMRDA through its official Twitter handle shared the details.
The 'made in India' metro rake manufactured by Bharat Earth Movers Ltd (BEML) will be used to carry out the trial runs.
For the electrification of the overhead line Catenary Maintenance Vehicle (CMV) delivered by the Bharat Earth Movers Ltd (BEML) was useful. This vehicle is meant for periodic inspection, patrolling and maintenance of overhead equipment. When both lines will be completely operational, this CMV will be used to attend to sites where equipment has broken down (if any), and will assist with erecting and restoring damaged catenary and contact wires. The CMV comes with a lifting platform and crane with an interchange basket.
The Mumbai Metro Line 2A and 7 will operate on 25kV 50Hz AC Supply. It is an important milestone for the commencement of the proposed metro trial run. Reportedly, the Chief Electrical Inspector to government of India (CEIG) has approved OHE electrification on the trial stretch, which was a major breakthrough especially at the time of pandemic.
