Mumbai Metro line 3 project estimated to cost Rs 7,000 crore more

The line 3 of Mumbai Metro is expected to cost Rs 30,000 crore. The earlier estimate, based on a detailed project report (DPR) from 2011, was Rs 23,136 crore.

“There is a gap between the approved cost and the actual completion cost. There is a provision to allow for revised costs, and we have already initiated that process. The gap is for the value of time loss and some changes that occur while implementing the project on ground,” said Ashwini Bhide, managing director, Mumbai Metro Rail Corporation (MMRC).

At 33.5 km, line 3 is the longest corridor of the Mumbai metro. The fully underground stretch runs along Colaba-Bandra-SEEPZ. The MMRC is the nodal agency for constructing this line.

The project is being financed through a mix of debt from Japan International Cooperation Agency (Jica), equal equity contribution from the central and state governments, and additional subordinate debt.

Bhide said the project was on time to be completed by 2021 as planned, but if a proposed depot at the Aarey Colony was delayed, there could be a problem. The metro project has faced protests over this depot in the western suburb of Mumbai. Green activists claim the construction of the depot will destroy green cover in the area.

Bhide said the allegation was baseless and the disputed stretch had been classified as grazing land. The MMRC now awaits clearance from the Tree Authority to cut some tree and construct the metro depot.

“It is crucial because our operations start from there. By the end of 2020, the first train will arrive, for which depot needs to be ready,” Bhide said. She added, “Earlier we had a cushion (for delay in clearance), which is now wiped out completely.”

Bhide expects 80 per cent of the Metro line’s tunneling work to be completed by December this year.

“Some additional tunneling will be completed by March–April next year. Station works are at different stages (of completion) and progressing well,” she said.

CBTC: The Technology behind Driverless Train.

By 2030, 5o Indian cities are expected to run on the mass rapid transport system. More people will migrate to cities in coming decades taking global city dwellers population to 6.4 billion. Conventional urban transport systems will not able to cope with the changes about ‘how and when we move’. The capacity of mass transit systems can rarely be expanded to the extent actually necessary in that case. In order to make more efficient use of existing infrastructure, existing metro lines are being modernised and increasing equipped with automated train control and safety system. More than 40 cities globally have adopted automated driverless metro trains. In India, demand for driverless metro train technology is very high. What makes automation possible in trains?
The technology behind driverless trains in called Communication Based Train Control (CBTC). CBTC technology operates through the communication between the train and equipment on the track for managing traffic. It helps identify the exact position of a train more accurately than traditional methods which depend on signal systems. The CBTC is going to be a radical move in the nation’s rail transport by displacing the presence of the loco pilot in the train. It ensures efficiency and safety of the metro in a truly international style.
Conventional metro rail requires signalling and intervention of train pilot. Whereas, the function of CBTC enabled trains is completely data based. In most CBTC rail networks, data between trains and trackside equipment are transferred using wireless communication networks, such as global system for mobile communications-railway (GSM-R) and wireless local area network (WLAN). For urban mass transit systems, WLAN is a better choice due to the availability of equipment. WLAN-based CBTC has been deployed across the major cities of the globe. In India, WLAN-based CBTC is under process in Kochi Metro Phase 1 and Delhi Metro line 8. Other Indian cities namely Ahmedabad, Mumbai, Hyderabad etc also plan to deploy driverless train technology.
In megacities like Mumbai, Delhi, Beijing and Tokyo, the number of people travelling during peak hours in very high. On automated lines, trains can run at a very short interval one after another. The capacity of an existing track can be increased by almost 50%. The difference of 90 seconds between trains is feasible. Additional trains can be deployed depending upon the need without disturbing the original timetable.
To make driverless train tech possible, additional systems like platform screens, platform track monitoring system, remote sensing and intrusion avoidance is a must. These systems eliminate the risk of fatality on tracks and improve system efficiency. If passenger pulls an emergency brake, the situation in the train can be accessed by control centre with the aid of passenger area surveillance. Since the train is connected to control centre through LAN, necessary measures can be taken to avoid any further incidence. Smoke detectors inside the train and on the track report to control room in case of fire and the train is halted at next stop.
Driverless trains are energy efficient due to optimised acceleration, traction and smooth braking. On the basis of line data, the automated system calculates exactly where and how the train should be accelerated or braked to arrive it punctually at next stop. Former train pilot can work as train attendant to service passengers and can act immediately during emergencies.
According to Union Internationale des Transports Publicis (UITP), by 2025 some 2300km of driverless metro lines will be operational in the world, compared with around 800km today. The increasingly widespread use of CBTC enabled transport systems along with rising standard of living in developing countries will encourage the competitiveness of automated technology. Almost all upcoming metro projects in India will run on driverless train tech. Kochi Metro was the first to implement CBTC followed by Delhi Metro Line 8. Mumbai Metro is expected to break global records as upcoming Line 2, Line 3, Line 4 and Line 7 have already issued financial bids to induct CBTC enabled trains. Today, most driverless trains run in Europe and the middle east. That is about to change as winds of automation are soon heading to India and China.

Mumbai’s first underground metro rail line has seen breakthrough as 28-km (50 per cent) tunnelling of Line 3 has been completed in a period 19 months. The Mumbai Metro 3, or line 3 is a 56-km line on the Colaba-Bandra-SEEPZ corridor.

The breakthrough was revealed by journalist Rajendra B. Aklekar on Twitter. The Mumbai Metro Rail Corporation (MMRC) launched the first tunnel boring machine (TBM)- Krishna-1 at Naya Nagar, Mahim in September 2017.

Since then the MMRC has worked in full steam with the help of 17 TBMs to tunnel the city, and are working towards the next 19 breakthroughs on the 33.5 km long metro-3 alignment.


There are 12 launching shafts to facilitate tunneling at Cuffe Parade, Eros Cinema, Azad Maidan, Science Museum, Siddhivinayak, Naya Nagar, BKC, Vidyanagari, Pali Ground, Sariput Nagar, Sahar Road, International Airport T2.
— Rajendra B. Aklekar (@rajtoday) June 10, 2019



The first breakthrough on alignment came in September 2018, followed by 12 more breakthroughs achieved at SEEPZ, CSIA T2, Sahar Station, MIDC, Domestic Airport T1, Dadar, Worli, Vidyanagari and Vidhan Bhavan over the next eight months till May 2019.

The longest line of tunnelling completed is the 3.9 km-long stretch between Vidyanagari and the Domestic Airport, and the shortest line is the 562-meter long Sariput Nagar to SEEPZ stretch. Totally, 19,504 segment rings were used to tunnel the completed 28 km stretch.

Transport revolution in India! Modi government bets on Metrolite train network for smaller cities; top facts

By: Debjit Sinha | New Delhi | Published: July 23, 2019 3:52:42 PM

Metrolite project: The proposed Metrolite system involves less capital cost, operation and maintenance expenditures compared to a regular Metro network. These specifications can make the system more viable for smaller cities.

The success of Delhi Metro has paved the way for the exponential growth of the rapid mass transit systems in several big cities across India.

India bets on ‘Metrolite’ systems for smaller cities! Following the unprecedented success of Delhi Metro, several big cities across India have started their own rapid mass transit systems. There is no doubt that metro networks have changed the way common people travel in these cities. Now, the Narendra Modi government wants to take forward the “success of metro rail” to cities with less ridership. To provide the rail-based mass rapid transit system to people in these cities, the central government was planning to bring in Light Urban Rail Transit System named “Metrolite” with lesser capacity at much less cost.

Top details about light urban rail transit system ‘Metrolite’ project

  • Cost-effective: The proposed Metrolite system involves less capital cost, operation and maintenance expenditures compared to a regular Metro network. These specifications can make the system more viable for smaller cities.
  • The balance between road traffic, rail traffic: The proposed system will have a dedicated path. This dedicated path will separate the road traffic with Metro lite system. Apart from this, for segregation with road traffic, fencing would be provided on either side of the network.
  • Proposals have been made for an integrated road and rail signaling system. This could be provided with priority for Metrolite system. Traffic marshals can be posted initially at crossings to enforce discipline.
  • Municipal corporations of the concerned cities will be entrusted with the responsibility to identify all possible paths for providing at-least single-track operation of Metrolite trains between two parallel roads.
  • If the road width in the cities does not permit to have both lines; one line can be provided on a particular road and the other line can be provided on a parallel road also. As an alternative, the entire road can be closed for road transport and the only train can be operated with pedestrian plazas, as per proposals made by the Central government.
  • Proposals have been made that there won’t be any AFC gates, X-ray baggage scanner, Platform screen doors and DFMD (Door Frame Metal Detectorare) in the Metrolite shelter. Ticket validators could be installed inside the train and in shelters with NCMC (National Common Mobility Card) or another ticketing systems. There could be random checking and heavy penalty will be slapped on the passengers traveling without a valid ticket in the system.
  • Standard gauge of 1435 mm width can be adopted for the Metrolite system. The ballast-less track has been proposed in elevated sections and embedded track on road for At-grade sections.
  • Metrolite trains with a maximum 12T axle load is to be adopted for passenger peak hour peak direction traffic (PHPDT) capacity from 2,000 to 15,000. Up-to 300 number of Passenger loading for 3-coach train unit. Trains will be capable of travelling in elevated, at grade and tunnel sections, as per proposals.
