Delhi Metro, India




Key Data


Delhi Metro

Stifling road traffic congestion in Delhi, population approximately 20 million, has become an economic liability. With more motor vehicles than Mumbai, Calcutta and Chennai combined, overcrowding and pollution was threatening the capital's ability to reach its potential in the rapidly expanding Indian economy.

Calcutta/Kolkata opened India's first metro (16.5km) in 1984, but the project did not inspire confidence in the Indian Government to promote further schemes.

Delhi Metro Rail Corporation (DMRC) was established by the Government of India and the Government of Delhi in March 1995 to build a new metro system in the capital. The project is being carried out in phases - Phase I (65.11km) and Phase II (128km) have been completed.

The capital investment for Phases I and II was $2.7bn. Thirty percent of the total investment was funded by Government of India (GoI) and Government of Delhi, while another 60% was financed through a loan from Japan International Cooperation Agency (JICA). DMRC paid back $100m to JICA by August 2010.

In 2011, the Delhi Metro project became the first railway project in the world to be certified for carbon credits for reducing greenhouse gas emissions, by the United Nations. DMRC saved 112,500MW of power by using regenerative brakes in the trains, and reduced carbon emissions by 630,000t yearly.

The project

After more than 40 years of studies into a rail-based mass transit system, DMRC began construction on 1 October 1998.

Funding principally came from a Japanese loan and Indian public funds, the latter in the form of equity. ,Phase I and Phase 2 were fully operational by January 2013.

The Delhi Metro consists of six lines, with a total length of 190km with 142 stations including 35 underground stations.

"Phase I and Phase II of Delhi Metro were fully operational by January 2013."

Delhi Metro was designed to be integrated with other public transport and DMRC signed an agreement with bus operator Delhi Transport Corporation (DTC) to integrate management and through-ticketing. However, limited take-up has led DMRC itself to supply around 200 buses of a quality consistent with Metro operations to work feeder routes to stations. Selected private bus operators will pay back DMRC over five years. There are 18 designated parking sites at Metro stations to further encourage use of the system.

In March 2010, DMRC partnered with Google India (through Google Transit) to provide train schedule and route information to mobile devices with Google Maps. This free service will allow the commuters to get the latest service information and plan their journeys.

Routes

Line 1 (Red Line) runs between Dilshad Garden and Rithala. It covers 25.1km, serves 21 stations and has a rolling stock of 26 trains. The first section of Line 1, from Shahdara to Tis-Hazari, opened in December 2002. A Phase II extension from Inderlok to Rithala opened in March 2004 and the Shahdara-Dilshad Garden section became fully operational in June 2008.

Delhi Airport Express Rail Link, India

The Delhi airport express rail link is a 22.7km long high speed metro rail operating between the New Delhi Railway Station and Dwarka Sector 21 in the suburbs of India's capital city New Delhi. It passes through the Indira Gandhi International (IGI) Airport before terminating at Dwarka Sector 21. It was opened to the public in February 2011 after 27 months of construction.


The section has two stations: Kirti Nagar (at grade) and Satguru Ram Singh Marg (elevated).Line 6 (Violet Line) runs between Central Secretariat and Badarpur. It covers 20.16km, serves 15 stations and has a rolling stock of 30 trains. The section between Central Secretariat and Sarita Vihar was opened in October 2010. The Sarita Vihar to Badarpur extension was opened in January 2011.

New Delhi Railway Station to Dwarka Sector 21 Airport Express Line was opened in February 2011. This 22.7km line has six stations with a rolling stock of eight trains.

Infrastructure

Line 2 is underground for its entire 11km length. All-but-one of its 15 stations have been built nearly 13m below ground using by cut-and-cover methods; Chawri Bazar, which lies some 20m down, needed tunnelling to be built.

All stations have escalators, elevators and tactile tiles to guide the visually impaired from station entrances to trains. Many of the stations are equipped for rainwater collection as part of their environmental policy.

One of the more challenging construction projects was Mandi House station on Line 3, managed by British company Mott Macdonald. As the station is located under a busy thoroughfare, much of the station had to be built top-down, with the diaphragm wall panels built from ground level to form the permanent walls of the station.

DMRC also provides subway facilities in all the underground metro stations as part of Phase II. Bicycle rental is also available at the Vishwa-vidyalaya, Pragati Maidan, Patel Chowk and Indraprastha metro stations.

Rolling stock

The first wave of rolling stock was manufactured by a consortium comprising Hyundai Rotem, Mitsubishi Corporation and Mitsubishi Electric Corporation. Initial sets were built by ROTEM in South Korea, with later examples completed in India by public sector undertaking Bharat Earth Movers Limited (BEML). BEML is also responsible for the manufacturing coaches under technology transfer agreement. The manufacturing is under progress.

The air-conditioned trains consist of four 3.2m-wide, stainless steel, lightweight, although eight is possible. The trains have automatic doors, secondary air suspension and brakes controlled by microprocessor.

"Delhi Metro has a fleet of 280 coaches, which DMRC runs as 210 trains every day."

Delhi Metro has a fleet of 280 coaches, which DMRC runs as 210 trains every day. Each train can accommodate about 2,290 people, 240 seated. Maximum speed is 80km/h (50mph), with a 20-second dwell time at stations. Train depots are located at Khyber Pass, Najafgarh, Shastri Park and Yamuna Bank.

In May 2011, BEML received a contract worth Rs9.2bn ($205m) from DMRC to supply 136 intermediate metro cars. The delivery is expected to be completed by the end of 2013.

In March 2008 Bombardier Transportation announced an €87m ($137m) contract for 84 MOVIA metro cars, a follow-on to an order for 340 placed in July 2007. The new vehicles were deployed as part of the Phase II expansion.

In September 2011, Bombardier received a $120m order for 76 additional MOVIA metro cars. This was a follow-on contract to an order placed for 114 vehicles in the middle of 2010. Deliveries under the new order were completed in 2012.

DMRC received the first MOVIA metro car from Germany in February 2009. The first 36 vehicles were manufactured in Goerlitz, Germany, and the remaining 388 cars were built at Bombardier's Indian manufacturing facility in Savli, South Gujarat.

In October 2012, Bombardier delivered the 600th MOVIA metro car to the DMRC.

Signalling and communications

The trains use centralised automatic train control (CATC) comprising automatic train operation (ATO), automatic train protection (ATP) and automatic train signalling (ATS) systems.

Intercoms are provided for emergency communication between the passengers and the driver in each coach, and on-train announcements are in Hindi and English. There are also route maps and LCD display systems in every coach.

Fare collection is through contactless, stored-value smartcards. The metro has its own police force, and a training school at Shastri Park is run in association with Hong Kong MTR for operational and maintenance staff. Security is supported by about 5,200 CCTV cameras at stations.

In October 2007 DMRC awarded Bombardier Transportation a $43m contract for the design, manufacture, supply, installation and testing of signalling equipment. The CITYFLO 350 system was installed on 37km of two of new line sections of the Phase II expansion.

The electronic interlocking, operation and automation control systems for the third line were supplied by Siemens Transportation Systems.

The future

Although the system operated at below projected passenger levels in 2007, partly ascribed to train capacity proving lower than anticipated, it has achieved an operating profit. About 2.2 million people daily used the Metro in 2012. It carries 5% of the city's commuters, and the project is not only meeting its aims in terms of attracting former road users and reducing road casualties, but it is stimulating economic development near to stations. Low-cost cycle hire and a secure parking trial was launched to further reduce road use.

Phase III and IV extensions, which will expand the network to413.8km, are scheduled to open in 2016 and 2021 respectively.

Phase III was approved in August 2011. It involves construction of 140km line with 92 stations and 17 interchange points. It is scheduled to be completed by 2016, carry about four million passengers and cost about Rs77.01bn ($1.4bn).

"Phase III and IV extensions will expand the network to 413.8km."

In addition to the expansions planned in these four phases, a new line is being constructed to link Noida Sector 62 and Greater Noida. It will cross the Indraprastha- Noida Sector 32 line.

The Ghaziabad Development Authority also has plans for a fifth phase, which could extend the Vaishali line (Blue Line) to Mehrauli via Indirapuram (Ghaziabad).

A welcome part of the system for overseas visitors is the 19.5km extension to Indira Gandhi International Airport. Journey times to the centre are cut to 16 minutes from the present one hour by road. The 135km/h (84mph) link will be extended as the airport adds new terminal facilities.

The first construction contracts, covering 7.5km of line, were awarded to Alpine-Samsung-HCC and Afcons in October 2007.

Delhi Metro is thought to have inspired greater support for mass transit systems; India has many projects now in the planning stage.
