Mumbai: MMRDA begins Dynamic trial run on Phase 1 of Metro Line 2A&7

The Mumbai Metropolitan Region Development Authority(MMRDA) on Saturday initiated Dynamic trial run on 20kilometre stretch between Dhanukarwadi and Aarey on both Metro Line 2A and 7. Meaning, the actual way of running a metro train which is performed while carrying passengers on board.

In Dynamic trail run, the metro train will be operated in synchronization with signals, platform screen doors, telecom among other crucial systems to ensure smooth operations. With integration of traction control and management system (TCMS) this trial run will be undertaken for two months, according to the MMRDA.

SVR Srinivas MMRDA commissioner said, "I am making sure that we put both the metro lines to public service as earliest as possible. To meet the expected deadline I am carrying out regular review meetings, doing site visits and also in contact with experts outside the country via video conferencing. The dynamic testing is a significant milestone in that direction only."

Interestingly, during this period of testing the prototype train will run at various speed. Various sub-systems and equipment will be tested under dynamic condition. Only after that, the train will be offered to RDSO (research, design and standards organisation) for mandatory performance and safety testing which will take another two months of time. Once that is achieved, the train will be sent for inspection and certification to commissioner of railway safety (CRS), MMRDA further explained.

On May 31st, Chief Minister Uddhav Thackeray had conducted static testing of trial run on the said 20km stretch between Dhanukarwadi and Aarey. The MMRDA after successfully completing all required steps intends to begin commercial operations on this stretch in in Phase-1 by October 2021. Before that, it will receive the delivery of 10 metro trains (two trains ever month) from the Bharat Earth Mover Ltd (BEML), Bangalore based Indian company.

The MMRDA meanwhile stated that despite Covid-19 induced lockdown restrictions worldwide it managed to overcome all challenges. The shipment of crucial components of the prototype train to be procured from Japan, Italy, Germany and South Korea had been affected. Besides, due to flight disruptions the availability of experts from international countries like Denmark, Finland, Spain, France and South Korea was not possible. However, it managed to handle the situation. The synchronization of propulsion and brake system was done through video conferencing across three different time zones--India, Europe and Japan.

The MMRDA after starting the phase 1 for public, aims to commence trial run on the entire metro line 2A and 7 in Phase 2 by end of December this year.
