Mumbai Metro, India
Mumbai is the second-fastest growing city in India. Its population is estimated to reach nearly 28 million by 2030, making it the fourth most populous metropolitan area in the world. Due to Mumbai’s rapid growth, road and rail infrastructure development has not been able to keep pace with the increasing demand over the last decades. As a result, the Mumbai Metropolitan Region Development Authority (MMRDA) unveiled a master plan in 2004 to provide mass rapid transit services. The system is designed to reduce traffic congestion in the city and supplement the existing network.
Mumbai Metro Line 4
Mumbai Metro Line 4 is a new metro line connecting Wadala to Kasarvadavali. The line consists of a 35.26 km elevated double track viaduct (U-girders) and includes a total of 30 stations.
In 2019, the line was extended by two stations to Gaimukh as Line 4A via an additional 2.66 km viaduct. The project was awarded to a consortium made up of DB Engineering & Consulting, Hill International and Louis Berger as an extension of the existing general consultancy contract.
The project includes civil infrastructure features such as elevated viaducts, stations, and depots with attached workshops, and rail systems such as tracks, signaling, telecommunications, power supply, automated fare collection and overhead contact line systems.
The metro line will provide a fast, convenient, reliable and safe mode of transport from Wadala – Ghatkopar – Mulund – Thane – Kasarvadavali to Gaimukh using the latest CBTC GoA4 technology.
Completion of the Mumbai Metro Line 4 project is crucial for increasing the capacity of the transport network and accommodating the city’s steadily growing population. Once fully operational, the line will carry 1.22 million passengers every day.
Mumbai Metro Lines 10 and 12
Mumbai Metro Line 10 is planned to be an elevated metro rail line in the length of 9.21 km extending from Gaimukh to Shivaji Chowk (Mira Road), with 4 elevated stations.
Mumbai Metro Line 12 will also be an elevated metro line with a total length of 20.76 km, reaching from Kalyan to Taloja and including 17 elevated stations. The depot is planned to be placed near the Pisarve Depot station, on a 20 ha plot of land.
The projects will provide rail systems such as tracks, signaling, telecommunications, power supply, automated fare collection and overhead contact line systems as well as civil infrastructure such as elevated viaducts, stations and depots with attached workshops.
Both lines are planned to be provided with a standard gauge of 1435 mm and 3200 mm wide rolling stock and to operate at maximum safe speed of 90 km/h.
The metro lines will provide a much faster and safer mode of transport from Gaimukh to Shivaji Chowk (Mira Road) and Kalyan to Taloja, also using the CBTC GoA4 technology.
