CC Engineers Begins Preliminary Design for MMRDA Lines 2 & 7

CC Engineers was recently awarded a contract through BEML Limited, a state-owned Indian enterprise, for the creation of maintenance simulators for the Mumbai Metropolitan Region Development Authority (MMRDA).

The MMRDA, chaired by the Minister for Urban Development in Maharashtra, is responsible for the creation and development of all infrastructure development in the Mumbai metro region. As one of the most densely populated metropolitan areas in the world, the MMRDA is developing the Mumbai metro with the goal of significantly reducing city traffic and helping Mumbai’s overburdened local train network. The entire project is estimated to be completed by 2025.

As a part of this pioneering project, CC Engineers is designing a set of maintenance simulators for 12 subsystems of the trains on lines 2 and 7 of the Mumbai metro. Line 2 of the Mumbai Metro, otherwise known as the “Yellow Line,” will be divided into two sections: The first section (2A) will be 18.589km long and run from Dahisar West to D.N. Nagar, while the second section (2B) will be 23.643km and run from D.N. Nagar to Mankhurd. The line is estimated to cost over $2bn and will contain 39 stations. Line 7 of the metro, known as the “Red Line,” will be 16.475km long and run from Dahisar East to Andheri East, with an additional extension to Terminal 2 of Chhatrapati Shivaji Maharaj International Airport. It will contain both a partially elevated section and an underground section and is expected to cost over $600m. Both lines transverse busy parts of the greater Mumbai metropolitan area, and the additional connection of the system to Mumbai’s airport, the second busiest airport in the country, and among those with the greatest passenger traffic in the world, makes Line 7 an especially important segment of the new metro.

The subsystems for which CC is creating simulators includes the train doors, HVAC, TCMS, brake and pneumatics, couplers, gangways, and the converter inverter and auxiliary converter inverter. As maintenance simulators, these simulators are an essential component in training new drivers to diagnose problems and give a correct and timely solution. Using state-of-the-art technology, they combine virtual and mixed reality to help drivers learn and explore essential train functions in a safe environment. The mixed media and advanced technology provide a high level of immersion for the drivers, and teach new drivers to take corrective action based on the standard TSD (troubleshooting directory).
