Delhi Metro is a metro system serving Delhi, Gurgaon, Noida, and Ghaziabad in the National Capital Region of India.[7] Delhi Metro is the world's thirteenth largest metro system in terms of length and a member of Nova Group of Metros.[8][9] Delhi Metro is India's third urban mass rapid transportation system, after the Kolkata Metro and Chennai MRTS. As of October 2014, the network consists of five colour-coded lines (Red, Blue, Green, Yellow, Violet), plus a sixth Airport Express line, with a total length of 193 kilometres (120 mi),[1] serving 140 stations (with 6 more Airport Express stations),[1] of which 38 are underground, five are at-grade, and the rest are elevated.[10] All stations have escalators, elevators, and tactile tiles to guide the visually impaired from station entrances to trains. It has a combination of elevated, at-grade, and underground lines, and uses both broad gauge and standard gauge rolling stock. Four types of rolling stock are used: Mitsubishi Rotem broad gauge, Bombardier Movia, Mitsubishi Rotem standard gauge, and CAF Beasain standard gauge.

Government of India. Besides construction and operation of Delhi metro, DMRC is also involved in the planning and implementation of metro rail, monorail and high-speed rail projects in India and providing consultancy services to other metro projects in the country as well as abroad.

As of November 2010, DMRC operates around 2,700 trips daily between 06:00 and 23:00 running with an interval of 2 minutes 40 seconds between trains at peak frequency.[11][12] The trains are usually of four and six coaches, but due to increase in the number of passengers, eight-coach trains are added on the Yellow Line (Jahangirpuri to HUDA city centre) and Blue line (Dwarka Sector-21 to Noida City Centre/Vaishali).[13] Yellow line being the first one with eight coach trains.[5][6][12][14] The power output is supplied by 25-kilovolt, 50-hertz alternating current through overhead catenary. The metro has an average daily ridership of 2.4 million commuters, and, as of August 2010, had already carried over 1.25 billion commuters since its inception.[15] The Delhi Metro Rail Corporation has been certified by the United Nations as the first metro rail and rail-based system in the world to get "carbon credits for reducing greenhouse gas emissions" and helping in reducing pollution levels in the city by 630,000 tonnes every year.[16]

Planning for the metro started in 1984, when the Delhi Development Authority and the Urban Arts Commission came up with a proposal for developing a multi-modal transport system for the city. The Government of India and the Government of Delhi jointly set up the Delhi Metro Rail Corporation (DMRC) registered on 3 May 1995 under The Companies Act, 1956. Construction started in 1998, and the first section, on the Red Line, opened in 2002, followed by the Yellow Line in 2004, the Blue Line in 2005, its branch line in 2009, the Green and Violet Lines in 2010, and the Delhi Airport Metro Express in 2011.

The recently opened Rapid MetroRail Gurgaon, whilst linked to it by the Yellow Line is a separate metro system (with a different owner/operator than the Delhi Metro), although tickets from the Delhi Metro can be used in its network.

The concept of a mass rapid transit for New Delhi first emerged from a traffic and travel characteristics study which was carried out in the city in 1969.[17] Over the next several years, many official committees by a variety of government departments were commissioned to examine issues related to technology, route alignment, and governmental jurisdiction.[18] In 1984, the Delhi Development Authority and the Urban Arts Commission came up with a proposal for developing a multi-modal transport system, which would consist of constructing three underground mass rapid transit corridors as well augmenting the city's existing suburban railway and road transport networks.[19]

While extensive technical studies and the raising of finance for the project were in progress, the city expanded significantly resulting in a twofold rise in population and a fivefold rise in the number of vehicles between 1981 and 1998.[19] Consequently, traffic congestion and pollution soared, as an increasing number of commuters took to private vehicles with the existing bus system unable to bear the load.[17] An attempt at privatising the bus transport system in 1992 merely compounded the problem, with inexperienced operators plying poorly maintained, noisy and polluting buses on lengthy routes, resulting in long waiting times, unreliable service, extreme overcrowding, unqualified drivers, speeding and reckless driving.[20] To rectify the situation, the Government of India and the Government of Delhi jointly set up a company called the Delhi Metro Rail Corporation (DMRC) on 3 May 1995, with E. Sreedharan as the managing director.[21]

Dr. E. Sreedharan handed over the charge as MD, DMRC to Shri Mangu Singh on 31 December 2011.


Physical construction work on the Delhi Metro started on 1 October 1998(in gujarat plant).[22] After the previous problems experienced by the

A fully automated, operatorless train system has been offered to Delhi Metro by the French defence and civilian technologies major Thales.[147]

The Airport Express line has introduced WiFi services at all stations along the route on 13 January 2012. Connectivity inside metro trains travelling on the route is expected in the future. The WiFi service is provided by YOU Broadband & Cable India Limited.[146]

The Delhi Metro uses cab signalling along with a centralised automatic train control system consisting of automatic train operation, Automatic Train Protection and automatic train signalling modules.[142] A 380 MHz digital trunked TETRA radio communication system from Motorola is used on all lines to carry both voice and data information.[143] For Blue Line Siemens Transportation Systems has supplied the electronic interlocking Sicas, the operation control system Vicos OC 500 and the automation control system LZB 700 M.[144] An integrated system comprising optical fibre cable, on-train radio, CCTV, and a centralised clock and public address system is used for telecommunication during train operations as well as emergencies.[145] For Red and Yellow lines ALSTOM has supplied signalling system and for line Green and Voilet Bombardier Transportation has supplied CITYFLO 350 signalling system.

Eight 6-car trains supplied by CAF Beasain were imported from Spain.[140] CAF holds 5% equity in the DAME project, Reliance Infrastructure holds the remaining 95%.[141] The trains on this line are of a premium standard compared to the existing metro trains and have in-built noise reduction and padded fabric seats. The coaches are equipped with LCD screens for entertainment of the passengers and also provide flight information for convenience of air travellers. The trains are fitted with an event recorder which can withstand high levels of temperature and impact and the wheels have flange lubrication system for less noise and better riding comfort.[105]

The standard gauge rolling stock is manufactured by BEML at its factory in Bangalore. The trains are four-car consists with a capacity of 1506 commuters per train,[138] accommodating 50 seated and 292 standing passengers in each coach.[133] These trains will have CCTV cameras in and outside the coaches, power supply connections inside coaches to charge mobiles and laptops, better humidity control, microprocessor-controlled disc brakes,[139] and will be capable of maintaining an average speed of 34 km/h (21 mph) over a distance of 1.1 km (0.68 mi).[133]

Standard gauge

The rolling stock for Phase II is being supplied by Bombardier Transportation, which has received an order for 614 cars worth approximately US$ 1100 million.[135] While initial trains were made in Görlitz, Germany and Sweden, the remainder will be built at Bombardier's factory in Savli, near Vadodara.[136] These trains are a mix of four-car and six-car consists, capable of accommodating 1178 and 1792 commuters per train respectively. The coaches possess several improved features like Closed Circuit Television (CCTV) cameras with eight-hour backup for added security, charging points in all coaches for cell phones and laptops, improved air conditioning to provide a temperature of 25 degrees Celsius even in packed conditions and heaters for winter.[137]

The broad gauge rolling stock is manufactured by two major suppliers. For the Phase I, the rolling stock was supplied by a consortium of companies comprising Hyundai Rotem, Mitsubishi Corporation, and MELCO.The coaches have a very similar look to MTR Rotem EMU,except with only 4 doors and use sliding doors.The coaches were initially built in South Korea by ROTEM,[127] then in Bangalore by BEML through a technology transfer arrangement.[131] These trains consist of four 3.2-metre (10 ft) wide stainless steel lightweight coaches with vestibules permitting movement throughout their length and can carry up to 1500 passengers,[132] with 50 seated and 330 standing passengers per coach.[133] The coaches are fully air conditioned, equipped with automatic doors, microprocessor-controlled brakes and secondary air suspension,[134] and are capable of maintaining an average speed of 32 km/h (20 mph) over a distance of 1.1 km (0.68 mi).[133] The system is extensible up to eight coaches, and platforms have been designed accordingly.[132]

Broad gauge

Maglev trains were initially considered for some lines of Phase 3, but DMRC decided to continue with conventional rail in August 2012.[130]

The Metro uses rolling stock of two different gauges. Phase I lines use 1,676 mm (5.499 ft) broad gauge rolling stock, while three Phase II lines use 1,435 mm (4.708 ft) standard gauge rolling stock.[125] Trains are maintained at seven depots at Khyber Pass and Sultanpur for the Yellow Line, Mundka for the Green Line, Najafgarh and Yamuna Bank for the Blue Line, Shastri Park for the Red Line, and Sarita Vihar for the Violet Line.[40][126][127][128][129]

Currently, DMRC has a pool of 208 train sets (65 4-car, 85 6-car and 58 8-car). At present, the Delhi Metro is operational on six lines where more than 2500 train trips are made each day traversing over 69000 km in a day. With Phase-III of the network expected to cover about 108 kilometres (67 mi), the Delhi Metro network will expand to operate over 295 kilometres (183 mi) by 2016, making it one of the fastest expanding Metro networks in the world carrying about 40 lakh (4 million) passengers.[123]

Delhi Metro has been registering a continuous increase in ridership since July, 2014, with the ridership figure creating a new record on the 8th of August, 2014. While on the 21st of July, 2014, Delhi Metro's ridership figure touched the high of 26.84 lakhs, on 4 August, it crossed the 27 lakh barrier to reach 27.05 lakhs. On the 8th of August, the ridership figure has now reached a new high of over 27.60 lakhs breaking all previous records.[122]

For the convenience of customers, Delhi Metro commuters have three choices for ticket purchase. The RFID tokens are valid only for a single journey on the day of purchase and the value depends on the distance travelled, with fares for a single journey ranging from to . Fares are calculated based on the origin and destination stations using a fare chart.[114] A common ticketing facility for commuters travelling on Delhi Transport Corporation (DTC) buses and the Metro was introduced in 2011.[115] Travel cards are available for longer durations and are most convenient for frequent commuters. They are valid for one year from the date of purchase or the date of last recharge, and are available in denominations of to . A 10% discount is given on all travel made on it.[116] A deposit of needs to be made to buy a new card which is refundable on the return of the card any time before its expiry if the card is not physically damaged.[114] Tourist cards can be used for unlimited travel on the Delhi Metro network over short periods of time. There are two kinds of tourist cards valid for one and three days respectively. The cost of a one-day card is and that of a three-day card is , besides a refundable deposit of that must be paid at the time of purchasing the card.[114]

Ticketing & Recharge

Security on the Delhi Metro is handled by the Central Industrial Security Force (CISF), who have been guarding the system ever since they took over from the Delhi Police in 2007.[108] Closed-circuit cameras are used to monitor trains and stations, and feed from these is monitored by both the CISF and Delhi Metro authorities at their respective control rooms.[109] Over 3500 CISF personnel have been deployed to deal with law and order issues in the system, in addition to metal detectors, X-ray baggage inspection systems, and dog squads which are used to secure the system. About 5,200 CCTV cameras have been installed, which cover every nook and corner of each Metro station. Each of the underground stations has about 45 to 50 cameras installed while the elevated stations have about 16 to 20 cameras each. The monitoring of these cameras is done by the CISF, which is in charge of security of the Metro, as well as the Delhi Metro Rail Corporation.[110] Intercoms are provided in each train car for emergency communication between the passengers and the train operator.[111] Periodic security drills are carried out at stations and on trains to ensure preparedness of security agencies in emergency situations.[112] DMRC is also looking at raising the station walls and railings for the safety of passengers.[113]


Trains operate at a frequency of 2 minutes 40 seconds to 5–10 minutes between 6:00 and 23:00 depending peak and off-peak time. Trains operating within the network typically travel at speed up to 40 km/h (25 mph), and stop for about 20 seconds at each station. Automated station announcements are recorded in Hindi and English. Many stations have services such as ATMs, food outlets, cafés, convenience stores and mobile recharge. Eating, drinking, smoking, and chewing of gum are prohibited in the entire system. The Metro also has a sophisticated fire alarm system for advance warning in emergencies, and fire retardant material is used in trains as well as on the premises of stations.[103] Navigation information is available on Google Transit.[104] The first coach of every train is reserved for women.[105][106] To make travelling by metro easier Delhi metro has launched an app for smartphones(iPhone and Android) that will provide information on various facilities like nearest metro station,fare,parking availability,tourist spots near metro stations,security and emergency helpline numbers.[107]

For the financial year ended March 2011, DMRC reported operating revenues of , a loss before tax of , and EBITDA (operating income before interest and depreciation) of . Property development (advertising and retail) contributed almost to the revenue. Ticket sales fetched , with the remainder coming from consultancy for other Metro projects in the country and miscellaneous sources. DMRC made an operating profit of per traveller. In the same period, "core" revenues were and EBITDA , with the remainder coming from external projects (e.g. Jaipur Metro), real estate, and consultancy.[102]

For the financial year ended March 2008, the Metro reported operating revenues of and a profit before tax of ,[101] which rose to and respectively for the financial year ended March 2009.[93]

Delhi Metro is one of the few metro systems in the world having an operational profit from the first day. In 2012, the Delhi Metro claimed to be one of only five metro systems in the world that operated at a profit without government subsidies. This was enabled by keeping maintenance costs to a minimum and harnessing additional revenue from advertisements and property development, apart from ticket sales.[97][98] The Metro also generates revenue by leasing out its trains and stations for film shoots. Due to its increasing association with Delhi as an image of the city's everyday life, it has been a popular filming location for production houses, and several films and advertisements have been shot on board.[99][100] Producers have to pay a minimum of 1 lakh (equivalent to INRBad rounding here or US$Bad rounding here in 2015) for every hour of filming, excluding taxes, security deposit and insurance.[99]

Revenue and profits

[95] Delhi Metro's implementation of Phase-I, which connected 65 km in the national capital, has been rated as "excellent" by the project's funding agency, the Japan International Cooperation Agency (JICA).[96]

The capital cost of Phases I and II has been estimated to be 144.30 billion (US$2.3 billion)/Arab at 2004 prices.[90] However, more recent estimates have placed the cost of construction at 2 billion (US$32 million)/Arab per kilometre.[91] Thirty percent of the total investment for Phases I and II has been raised through equity capital with the Government of India (GoI) and Government of Delhi contributing equal shares,[90] and approximately another 60 percent has been raised as either long-term or subordinate debt, through soft loans from the Japan Bank for International Cooperation.[92] The rest of the investment is proposed to be recovered from internal revenues through operations and property development.[90] The Metro also received 19143 million (US$310.1 million) as grant-in-aid from various agencies for the financial year ending March 2009.[93] As of 7 August 2010, Delhi Metro has paid back an amount of 5676.3 million (US$92 million), which includes loan amount for Phase I and interest amounts for Phases I and II, to the Japan International Cooperation Agency (JICA).[94]



Apart from these lines in Phases I to IV, plans have been mooted to construct a new line from Noida Sector 62 to Greater Noida which will intersect Indraprastha – Noida Sector 32 line.[87] The Ghaziabad Development Authority is planning to extend Delhi Metro lines deeper into Ghaziabad through extension of the Blue Line from Vaishali to Mehrauli via Indirapuram. The independently operated Gurgaon Metro, work on which is going on and has a deadline of 2013, will also interchange with the Delhi Metro at Sikandarpur station on Yellow line.[88] For the year 2012-13, Noida development Authority has allocated Rs 5 billion for Metro extension, with City Center Metro line being extended till the crossing of Sector 71 and 72.[89]

Delhi Metro Masterplan 2021. Only those proposed lines are included here which are very likely to get built. Other proposed lines are not included.

Phase IV has a 2021 deadline, and tentatively includes further extensions to Sonia Vihar, Burari, Mukundpur, Reola Khanpur, Palam, Najafgarh, Narela, Ghazipur, Noida sector 62, extensions of Violet line, Green line, Line 8, having a total length of over 100 km.[34][85][86] There might be some changes in plan before actual construction starts on these lines.

Phase IV

For the first time Delhi Metro will construct ring lines in Phase III. Till Phase II, Delhi Metro focused on expanding the reach of metro and thus built long radial lines. However, in Phase III, Delhi Metro is aiming to interconnect existing lines by ring lines to improve connectivity. This will not only help in reducing distances but will also relieve radial lines of some congestion.

Phase III will have 28 underground stations covering 41 km.[82] More than 20 tunnel boring machines are expected to be simultaneously used during construction of Phase III.[83] Delhi Metro is expecting a ridership of 4 million after completion of Phase III. DMRC has decided to use communication based train control (CBTC) for signaling which will allow trains to run at a short headway of 90 seconds.[84] Keeping this in mind and other constraints, DMRC changed its decision to build 9 car long stations for new lines and instead opting for shorter stations which can accommodate 6 car trains.

Out of 2 new lines and 11 route extensions proposed for Phase III, cabinet approvals have been obtained for 2 new lines and 10 line extensions totaling 167.27 km, with an estimated cost of 350 billion (US$5.7 billion).[78] Construction has already begun on many of these. In April 2014 the Delhi governor gave approval for two further extensions.[79] All the approved lines are:

Phase III

Delhi Metro was planned to be built in phases spread over around 20 years as with each phase having a target of five years and end of one phase marking the beginning of another. Phase I (65 km) and Phase II (125 km) were completed in 2006 and 2011, respectively, and Phase III and Phase IV are scheduled for completion in 2016 and 2021, respectively. Work on Phase III started in 2011 while planning for Phase IV has begun. Ex-chief of DMRC hinted that by the time Phase IV is completed, the city will need Phase V to cope with rising population and transport needs.[77]

The Airport Express line runs for 22.7 km (14.1 mi) from New Delhi Railway Station to Dwarka Sector 21, linking the Indira Gandhi International Airport. The line was operated by Delhi Airport Metro Express Pvt. Limited (DAMEL), a subsidiary of Reliance Infrastructure, the concessionaire of the line till 30 June 2013 and is now being operated by DMRC.[70] The line was constructed at a cost of 57 billion (US$920 million), of which Reliance Infrastructure invested 28.85 billion (US$470 million) and will pay fees on a revenue-share model.[71] The line has six stations (Dhaula Kuan and Delhi Aerocity became operational on 15 August 2011), with some featuring check-in facilities, parking, and eateries.[72] Rolling stock consists of six-coach trains operating at intervals of ten minutes and having a maximum speed of 135 km/h (84 mph).[72] Originally scheduled to open before the 2010 Commonwealth Games, the line failed to obtain the mandatory safety clearance, and was opened on 24 February 2011, after a delay of around 5 months. After 16 months of commencement of operations, the line was shut down for repairs of the viaducts on 8 July 2012.[73][74] The line reopened on 22 January 2013.[75] On 27 June 2013 Reliance Infrastructure Ltd intimated DMRC that they are unable to operate the line beyond 30 June 2013. Following this DMRC took over operations of Airport Express line from 1 July 2013 with an Operations and Maintenance team of 100 officials to handle the line.[76]

The Violet Line is the most recent line of the Metro to be opened, and the second standard-gauge corridor after the Green Line. The 23.2 km (14.4 mi) long line connects Badarpur to Mandi House, with 9 km (5.6 mi) being overhead and the rest underground.[40] The first section between Central Secretariat and Sarita Vihar was inaugurated on 3 October 2010,that just hours before the inaugural ceremony of the 2010 Commonwealth Games, and connects the Jawaharlal Nehru Stadium, which was the venue for the opening and closing ceremonies of the event.[68] Completed in just 41 months, it includes a 100 m (330 ft) long bridge over the Indian Railways mainlines and a 167.5 m (550 ft) long cable-stayed bridge across an operational road flyover, and connects several hospitals, tourist attractions, and a major industrial estate along its route.[40] Services are provided at intervals of 5 min.[68] An interchange with the Yellow Line is available at Central Secretariat through an integrated concourse.[40] On 14 January 2011, the remaining portion from Sarita Vihar to Badarpur was opened for commercial service, adding three new stations to the network and marking the completion of the line.[69] The most recent section, between Mandi House and Central Secretariat, was opened on 26 June 2014.

Violet Line

Violet Line

Opened in 2010, the Green Line was the first standard-gauge corridor of the Delhi Metro.[39] The fully elevated line connects Mundka with Inderlok, running for 15.1 kilometres (9.4 mi) mostly along Rohtak Road with a branch line connecting the line's Ashok Park Main station with Kirti Nagar station on the Blue Line. The line consists of 17 stations including an interchange station covering a total length of 18.46 km. The line was opened in two stages, with the 15.1 km Inderlok - Mundka section opening on 3 April 2010, and the 3.5 km Kirti Nagar - Ashok Park Main branch line on 27 August 2011.[65] An interchange with the Red line is available at Inderlok station via an integrated concourse.[66] This line also has the country's first standard-gauge maintenance depot at Mundka.[67]

Green Line

The Blue Line was the third line of the Metro to be opened, and the first to connect areas outside Delhi.[56] Mainly elevated and partly underground,[57] it connects Dwarka Sub City in the west with the satellite city of Noida in the east, covering a distance of 47.4 kilometres (29.5 mi).[56] The first section of this line between Dwarka and Barakhamba Road was inaugurated on 31 December 2005, and subsequent sections opened between Dwarka – Dwarka Sector 9 on 1 April 2006, Barakhamba Road – Indraprastha on 11 November 2006, Indraprastha – Yamuna Bank on 10 May 2009, Yamuna Bank – Noida City Centre on 12 November 2009, and Dwarka Sector 9 – Dwarka Sector 21 on 30 October 2010.[45] This line crosses the Yamuna River between Indraprastha and Yamuna Bank stations,[41] and has India's second extradosed bridge across the Northern Railways mainlines near Pragati Maidan.[58] A branch of the Blue line, inaugurated on 8 January 2010, takes off from Yamuna Bank station and runs for 6.25 kilometres (3.88 mi) up to Anand Vihar in east Delhi.[59] It was further extended up to Vaishali which was opened to public on 14 July 2011.[60][61] A small stretch of 2.76 kilometres (1.71 mi) from Dwarka Sector 9 to Dwarka Sector 21 was inaugurated on 30 October 2010.[62][63] Interchanges are available with the Yellow Line at Rajiv Chowk station,[57] Green line at Kirti Nagar, Violet line at Mandi House and with the Indian Railways network at the Anand Vihar Railway Terminal and Anand Vihar ISBT.[64]

Blue Line

Blue Line

The Yellow Line was the second line of the Metro and was the first underground line to be opened.[47] It runs for 44.36 kilometres (27.56 mi) from north to south and connects Jahangirpuri with HUDA City Centre in Gurgaon. The northern and southern parts of the line are elevated, while the central section through some of the most congested parts of Delhi is underground. The first section between Vishwa Vidyalaya and Kashmere Gate opened on 20 December 2004, and the subsequent sections of Kashmere Gate – Central Secretariat opened on 3 July 2005, and Vishwa Vidyalaya – Jahangirpuri on 4 February 2009.[45] This line also possesses the country's deepest Metro station (the second deepest metro station in the world)[48] at Chawri Bazaar, situated 30 metres (98 ft) below ground level.[49][50] On 21 June 2010, an additional stretch from Qutub Minar to HUDA City Centre was opened, initially operating separately from the main line. However, Chhatarpur station on this line opened on 26 August 2010. Due to delay in acquiring the land for constructing the station, it was constructed using pre-fabricated structures in a record time of nine months and is the only station in the Delhi metro network to be made completely of steel.[51][52] The connecting link between Central Secretariat and Qutub Minar opened on 3 September 2010.[53] Interchanges are available with the Red Line and Kashmere Gate ISBT at Kashmere Gate station, Blue Line at Rajiv Chowk Station, Violet Line at Central Secretariat, Rapid MetroRail Gurgaon at Sikandarpur and with the Indian Railways network at Chandni chowk Delhi Junction Railway station and New Delhi New Delhi railway stations.[54][55] Yellow line is the first line of Delhi Metro which has phased out all four coach trains with six and eight coach configuration. The Metro Museum at Patel Chowk Metro station is a collection of display panels, historical photographs and exhibits, tracing the genesis of the Delhi Metro. The museum was opened on January 1, 2009.[48]

On 12 July 2009, a section of bridge collapsed while it was being erected at Zamrudpur, near East of Kailash, on the Central Secretariat – Badarpur corridor. Six people died and 15 were injured.[30] The following day, on 13 July 2009, a crane that was removing the debris collapsed, and with a bowling pin effect collapsed two other nearby cranes, injuring six.[31] On 22 July 2009, worker at Ashok Park Metro station was killed when a steel beam fell on him.[32] Over a hundred people, including 93 workers, have died since work on the metro began in 1998.[33]

On 19 October 2008, a girder launcher and a part of the overhead Blue Line extension under construction in Laxmi Nagar, East Delhi collapsed and fell on passing vehicles underneath. Workers were using a crane to lift a 400-tonne concrete span of the bridge when the launcher collapsed along with a 34-metre (112 ft) long span of the bridge on top of a Blueline bus killing the driver and a labourer.[29]

Construction accidents

The first line of the Delhi Metro was inaugurated by Atal Behari Vajpayee, the then Prime Minister of India, on 24 December 2002,[26] and thus, it became the second underground rapid transit system in India, after the Kolkata Metro.
