Dhaka Mero Rail's electro-mechanical system.

Dhaka, Jan 09 – The commercial operation of newly opened metro rail continues on Uttara-Agargaon part of the Dhaka Metro Line-6 based on the latest electrical & mechanical (E&M) system commissioned successfully by the Railway Business, Transportation Infrastructure Business of L&T Construction.

The Integrated E&M Systems works including Overall System Integration was successfully executed by Indian multinational conglomerate company, Larsen & Toubro that is widely known as L&T.

The commercial operation of the Phase-1 (11.4 km) of the Dhaka Metro Line 6 commenced upon achievement of this milestone. This stretch was flagged off by Prime Minister Sheikh Hasina on December 28.

The 20-km MRTS (Mass Rapid Transit System) Line-6, funded by the Japanese International Cooperation Agency (JICA) is the first Metro Rail system in Bangladesh that would connect Uttara to Motijheel in Dhaka City. It passes through the busy areas of Pallabi and Mirpur. Line 6 has 16 stations and a Maintenance Depot.

The ‘Integrated E&M Systems works involves ballastless track work in the viaduct, ballasted track in the depot, 1500V DC Traction Sub Stations (TSS), DC Overhead Catenary System (OCS), Energy Storage Systems (ESS), Communication Based Train Controls (CBTC) Signaling System, Telecommunication systems and radio communication based on LTE, Automatic Fare Collection system (AFC), Platform Screen Doors, Lifts, Escalators, and overall System Integration.

The project also includes EHV cabling, GIS based Receiving Sub Stations (RSS), 33 kV cable ring mains, Auxiliary Sub Stations (ASS) & SCADA systems.

The MRT project also features several state-of-the-art technologies including the Automatic Train Operation (ATO) mode, LTE-based radio communication and an Energy Storage System to utilize regenerative braking, said L&T CEO and Managing Director SN Subrahmanyan about the achievement.

Several advanced systems were installed in the metro project, including long-term evaluation (LTE) system.

Considering the safety of passengers, the Communication Based Train Controls (CBTC) Signaling System is there to enable the metro operations with a 3-mintue headway between two trains, while there is automated train protection system to avoid any train collision.

The multinational construction company also successfully executed metro projects and metro systems in India, Saudi Arabia, Qatar and Mauritius. - UNB
