The main objective of the Mumbai Metro is to provide services to people within a distance of between 1 and 2 kilometer’s, and to serve the areas which is not connected by the Suburban Rail network. The Mumbai-Metro is a transit system will connects the New Mumbai and their Metropolitan regions. It is designed to reduce the traffic in the city, and overcrowded Mumbai Suburban Railway Stations. It will built in three phases under 15-year period, while its overall competition is expected in year 2025. After completion, these system will comprise Eight high-capacity metro railway lines, with a total of almost 235 kilometers with 24% underground and the 76% elevated, along with 200 stations.
As on August 2018, Mumbai metro consisted 1 operational line (elevated metro from Versova to Ghatkopar) and the other 4 lines are under construction.
Line 1 of Mumbai Metro is operated by Metro One Operation Private Limited (MOOPL). A joint contract between Transdev joint venture (70%) and Reliance Infrastructure (30%). The other lines i.e 2, 4, 6, 7 are under construction, 5th line and their expansion will be built by MMRDA, the 3rd line is underground is also under construction will be built by Mumbai Metro Railway Corporation Limited (MMRCL). The total financial outlay for the metro system beyond the operational Line 1 is ₹821.72 billion (US$12.46 billion and €11.12 billion in 2018), which will be funded by mix of equity, bilateral, multilateral and syndicated debt.
In June 2006, Manmohan Singh (P.M) laid down the foundation stone for the 1st phase of the Mumbai Metro project, however the construction work began in February, 2008.A trial run was conducted in May 2013 which became successful, and the system’s 1st line entered into operation on 8 June 2014. Many metro projects were delayed because of opposition of political parties, late environmental clearances and land acquisition problems. They proposed 15 km line which would connects the Kalyan and Shil Phata with 13 stations by bringing metro projects to Kalyan East, Dombivli, Ambernath and Diva.
The Maharashtra Government through the MMRDA had a meeting in order to improve the transportation scenario in Mumbai which are efficient, economically suitable and environment friendly. In this context, a detailed study was carried out under Indo-German technical co-operation between the years 1997-2000.
The study recommended a mass transportation corridor from Andheri to Ghatkopar as potentially bankable and economically suitable. In May 2004, These study was updated by MMRDA. These proposals will helpful for reducing the vehicle traffic from roads and reducing time between various regions. However,DMRC had prepared the master plan for Mumbai metro, where they recommended for extending the Andheri-Ghatkopar section to Versova. The State Government annoounced the project as a “Public Vital Infrastructure Project” and Appointed the MMRDA as a Project Implementation Agency.
The master plan revealed by MMRDA in 2004 comprised a total of 146.5 kilometers of track, from which 32 kilometers were underground. The Mumbai Metro was proposed to be built in three phases with an estimated cost of ₹19,525 crore. In September 2009, Due to suggestion by MMRDA, the line between Hutatma Chowk – Ghatkopar was reduced to Hutatma Chowk and Carnac Bunder.
In 2011, the MMRDA proposed a plan for the expansion of Colaba-Bandra-seepz Metro Line. Meanwhile, the MMRDA had decided to expand the line by running it from Bandra to Chatrapati Shivaji International Airport. The 33.5-kilometer wider Colaba-Bandra-seepz line were to be built at a cost of ₹21,000 crore , for becoming the city’s first underground metro line with 27 metro stations.
On 27 Feb 2012, the Union Government gave approval for the plan and for 3rd Line. Cost for these project is being borrowed from Japanese International Cooperation Agency of about 50% and by the state government of about 16%, 14% from the central government. In July 2012, the MMRDA declared further plans to add more metro lines to its current plan. In 2013,The MMRDA announced to convert the Lokhandwala-seepz-Kanjurmarg monorail route into a metro line.
RIIL consulted with various international rolling stock builders to provide the train fleet for the Mumbai Metro. Many bidders were for the contract like Kawasaki, Alstom, Siemens ,Bombardier, but CSR Nanjing of China were chosen for supplying rolling stock at the cost of ₹6 billion(INR). In May 2008, CSR had completed the first 16 trains with four cars each. The first ten trains were announced to ready for operation on January 2013.
The coaches consists of fire retardant, air-conditioned and were designed to reduce noise and ample space for standing passengers. The coaches includes LCD screens, 3D route maps, first-aid kits, wheelchair facilities, fire-fighting equipment and intercom systems which permits to communicate with the metro train driver. Each coach had a black box which will be helpful in accident investigations. The trains were capable of carrying almost 1,000 passengers in a four-car unit.
In 2018, the MMRCL chosed Alstom company to supply 31 six car trains for 3rd Line. The trains were capable of driver-less operations which was built at Alstom’s factory, Sri City (Andhra Pradesh).
In 2018, MMRDA receives a tender to Bharat Earth Movers Limited (BEML) for supply of 63 sets of train i.e 378 coaches for 2nd Line and 7th Line at a total cost of ₹3,015 crores. Driver-less trains were manufactured at BEML’s factory, Bengaluru and were expected to get delivery between the year 2020 and 2022.
Almost 97% of metro corridors all over the world runs on direct current (DC),while the Mumbai Metro will runs on alternating current (AC) which is cost intensive. MMRDA’s joint project director Dilip Kawathkar had stated that the ‘AC’ power was chosen after a accurate study by the team of experts”. They found that the AC model was a better option than DC. Experts believed that the decision to use AC will reduced the project cost of underground lines by 15% .It is required for the rail to work on ‘AC’ current.
Signalling and communications
The Mumbai Metro had an Advanced Signalling System including an automatic train protection system (ATPS) and Automated Signalling System to control train movements on 11-kilometer in 1st Line. Siemens did supply the signalling systems which are required for the Metro project. The Thales Group did supply the Metro’s communication systems. While, the network signaling system and train control systems will based on the LZB 700M Technology.
Maharashtra Clears Three New Metro Routes for Mumbai
The Maharashtra Cabinet had recently cleared three new Metro corridors for Mumbai with an estimated cost of Rs. 24,000 crore.
One route will serve parts of eastern and southern Mumbai while the other two routes will serve the suburbs in Thane. The Wadala-GPO Metro 11 corridor,expected to built at a cost of Rs. 8,000 crore for 14 km’s long along with partly elevated and partly underground with stations like – Wadala RTO, Ganesh Nagar, BPT Hospital (elevated) and Sewri Metro, Hay Bunder, Coal Bunder, Darukhana, Wadi Bunder, Clock Tower, Carnac Bunder and CSMT Metro (all underground).
The Gaimukh-Shivaji Chowk Metro 10 corridor for 11 kms long and will five stations which includes – Gaimukh, Gaimukh Retibunder, Versova Chaarphata, Kashi-Mira and Shivaji Chowk in connecting Thane district.
The next is the Kalyan-Taloja Metro 12 corridor, which is the longest route at 25 kms to built at an estimated cost of Rs. 11,000 crore with 18 stations which will serves to some important industrial centers in the region.
The Stations are: APMC Kalyan, Ganesh Nagar, Pisawali Gaon, Golwali, Dombivli MIDC, Sagaon, Sonarpada, Manpada, Hadutane, Kolegaon, Niljegaon, Wadavali, Bale, Vaklan, Turbhe, Pisawe Depot, Pisawe and Taloja.
These new metro corridors will reduce the journey timings by 50-75 per cent compared to road, and it reduced the road traffic upto 35 percent.
