MMRDA begins pre-trial run activities of first metro trainset in Charkop depot

Mumbai, India (Urban Transport News): Before commencing trial runs of metro train on much-awaited Mumbai Metro's Line 2A (Dahisar - DN Nagar) and Line 7 (Andheri East - Dahisar East), the Mumbai Metropolitan Region Development Authority (MMRDA) conducted a dynamic test of the first train set on 25th February 2021.

The first train set was received at Charkop depot on 28th January 2021 from BEML Limited. This is the first six-car train supplied under the MRS1 contract for the supply of 96 trains awarded to BEML. Since then BEML engineers have conducted various activities. They successfully split the train into two units of 3 cars each which are being prepared for energization and limited movement using only hard-wired commands.

The train was energized first time on 9th February 2021 after testing train high voltage traction power systems including pantograph, propulsion equipment and brake systems. The first self-powered movement was conducted between February 16-17, 2021.

Now, with integrated six-car train formation dynamic low-speed testing over the 520 metres test track in Charkop depot was conducted. RA Rajiv, Metropolitan Commissioner, MMRDA has flagged off the first train set for the dynamic testing run activities.

After completion of the above, functionality of the various subsystems like Vehicle Control Circuit (VCC), TCMS Control & Interfaces with the different subsystem, Shore Supply Units, High Voltage, Propulsion fine-tuning with Brake System, Auxilary Power Supply, Brakes & Pneumatics, Doors System, Air Conditioning, Lightening, Passenger Announcement & Passenger Information System (PA-PIS) etc. shall be undertaken to verify each subsystem individually with integrated train testing with the depot.

According to MMRDA officials, the above activities may take one month and once the connectivity to the mainline is achieved, trial runs on the mainline will also start. MMRDA is expecting the arrival of the second train set in March and they may commence the combined integrated testing of the train with the signalling systems.

MMRDA expects to complete the trial runs in the next 4-5 months, after which it be ready to start the commercial run on Mumbai Metro's Line 2A and Line 7 in the service of Mumbaikers.
