Delhi Metro Rail Corporation Limited ( DMRC ) , a state - owned company with equal equity participation from Government of India and Government of Delhi , built and operates the Delhi Metro . Delhi Metro is the world 's 12th longest metro system in length and 16th largest in ridership . A member of CoMET , the network consists of five colour - coded regular lines and the faster Airport Express line , with a total length of 218 kilometres ( 135 mi ) serving 164 stations ( including 6 on Airport Express line ) . The system has a mix of underground , at - grade , and elevated stations using both broad - gauge and standard - gauge . The power output is supplied by 25 - kilo volt , 50 - hertz alternating current through overhead catenary . The trains are usually of four , six , and eight - coach length . DMRC operates over 3,000 trips daily , with first trains starting at around 05 : 00 and last at 23 : 30 . In the financial year 2016 - 17 , Delhi metro had an average daily ridership of 2.76 million passengers , and served 100 crore ( 1.0 bn ) riders in total during the year . The Delhi Metro Rail Corporation was certified by the United Nations in 2011 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 . 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 . Delhi Metro Rail Corporation ( DMRC ) was incorporated in May 1995 , construction started in 1998 , and the first section , on the Red Line , opened in 2002 . The development of network was divided into phases , Phase I containing 3 lines was completed by 2006 , and Phase II in 2011 . Phase III is scheduled for completion by 2018 ( originally planned for 2016 ) . Rapid MetroRail Gurgaon which opened in 2013 , whilst linked to Delhi Metro by the Yellow Line is a separate metro system ( with a different owner / operator than the Delhi Metro ) , although tokens from the Delhi Metro can be used in its network .

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 . In 1984 , the bubli and the bitu 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 . 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 . 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 . 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 . 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 . Dr. E. Sreedharan handed over the charge as MD , DMRC to Mr. Mangu Singh on 31 December 2011 . Construction ( edit ) Physical construction work on the Delhi Metro started on 1 October 1998 . After the previous problems experienced by the Kolkata Metro , which was badly delayed and 12 times over budget due to `` political meddling , technical problems and bureaucratic delays '' , DMRC is a special purpose organisation vested with great autonomy and powers to execute this gigantic project involving many technical complexities , under a difficult urban environment and within a very limited time frame . DMRC was given full powers to hire people , decide on tenders and control funds . The DMRC then consulted the Hong Kong MTRC on rapid transit operation and construction techniques . As a result , construction proceeded smoothly , except for one major disagreement in 2000 , where the Ministry of Railways forced the system to use broad gauge despite the DMRC 's preference for standard gauge . The first line of the Delhi Metro was inaugurated by Atal Bihari Vajpayee , the Prime Minister of India , on 24 December 2002 , and thus , it became the second underground rapid transit system in India , after the Kolkata Metro . The first phase of the project was completed in 2006 , on budget and almost three years ahead of schedule , an achievement described by Business Week as `` nothing short of a miracle '' . Construction accidents ( edit ) 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 - long ( 112 ft ) span of the bridge on top of a Blueline bus , killing the driver and a labourer . 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 . 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 . On 22 July 2009 , worker at Ashok Park Metro station was killed when a steel beam fell on him . Over a hundred people , including 93 workers , have died since work on the metro began in 1998 .

It is partly elevated and partly at grade , and crosses the Yamuna River between Kashmere Gate and Shastri Park stations . The inauguration of the first stretch between Shahdara and Tis Hazari on 24 December 2002 caused the ticketing system to collapse due to the line being crowded to four times its capacity by citizens eager to have a ride . Subsequent sections were inaugurated from Tis Hazari -- Trinagar ( later renamed Inderlok ) on 4 October 2003 , Inderlok -- Rithala on 31 March 2004 , and Shahdara -- Dilshad Garden on 4 June 2008 . The red line has two interchange stations , the first Kashmere Gate with the Yellow Line and Violet Line and the second Inderlok with the Green Line . Beginning 24 November 2013 , a total of six coach trains were eventually commissioned on the Red Line . Yellow Line Yellow Line ( edit ) Inside a Delhi Metro on the yellow line Main article : Yellow Line The Yellow Line was the second line of the Metro and was the first underground line to be opened . It runs for 49 kilometres ( 30 mi ) from north to south and connects Samaypur Badli with HUDA City Centre in Gurgaon . The northern and southern parts of the line are elevated , while the central section which passes 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 . This line also possesses the country 's deepest Metro station ( the second deepest metro station in the world ) at Chawri Bazaar , situated 30 metres ( 98 ft ) below ground level . 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 delays 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 . The connecting link between Central Secretariat and Qutub Minar opened on 3 September 2010 . On 10 November 2015 , the line was further extended between Jahangirpuri and Samaypur Badli in Outer Delhi . 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 , Airport Express ( Orange ) Line at New Delhi , Rapid MetroRail Gurgaon at Sikandarpur and with the Indian Railways network at Chandni chowk and New Delhi . 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 1 January 2009 . Blue Line ( edit ) Blue Line Main article : Blue Line The Blue Line was the third line of the Metro to be opened , and the first to connect areas outside Delhi . Mainly elevated and partly underground , 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 ) . 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 . This line crosses the Yamuna River between Indraprastha and Yamuna Bank stations , and has India 's second extradosed bridge across the Northern Railways mainlines near Pragati Maidan . 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 . It was further extended up to Vaishali which was opened to public on 14 July 2011 . A small stretch of 2.76 kilometres ( 1.71 mi ) from Dwarka Sector 9 to Dwarka Sector 21 was inaugurated on 30 October 2010 . Interchanges are available with the Yellow Line at Rajiv Chowk station , Green line at Kirti Nagar , Violet line at Mandi House , Airport Express ( Orange ) line at Dwarka Sector 21 and with the Indian Railways network and Interstate Bus Station ( ISBT ) at Anand Vihar station , which connects with Anand Vihar Railway Terminal and Anand Vihar ISBT . Green Line ( edit ) Green Line Main article : Green Line Opened in 2010 , Green Line ( Line 5 ) is the fifth line of the Delhi Metro network and the first line on standard gauge , as opposed to previous broad gauge lines . It runs between Inderlok ( station on the Red Line ) and Mundka with a branch line connecting the line 's Ashok Park Main station with Kirti Nagar station on the Blue Line . The completely elevated line , built as part of the Phase - II of Delhi Metro runs mostly along the busy NH 10 route in West Delhi . The line consists of 17 stations including an interchange station covering a total length of 18.46 km . This line also has the country 's first standard - gauge maintenance depot at Mundka . The line was opened in two stages , with the 15.1 km Inderlok -- Mundka section opening on 3 April 2010 ( 1 ) and the 3.5 km Kirti Nagar -- Ashok Park Main branch line on 27 August 2011 . On 6 August 2012 , in a step that will improve commuting in National Capital Region , the Union government has approved extension of Delhi Metro from Mundka to Bahadurgarh in Haryana . The 11.18 km metro stretch will have seven stations at Mundka Industrial Area , Ghevra , Tikri Kalan , Tikri Border , Modern Industrial Estate , Bahadurgarh Bus Stand and City Park between Mundka and Bahadurgarh . Violet Line ( edit ) Violet Line Main article : Violet Line The Violet Line is the sixth line of the Metro to be opened , and the second standard - gauge corridor after the Green Line . The 40 - kilometre - long ( 25 mi ) line connects Escorts Mujesar in Faridabad to Kashmere Gate in New Delhi , with 22.8 km ( 14.2 mi ) being overhead and the rest underground . The first section between Central Secretariat and Sarita Vihar was inaugurated on 3 October 2010 , 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 . Completed in just 41 months , it includes a 100 - metre - long ( 330 ft ) bridge over the Indian Railways mainlines and a 167.5 - metre - long ( 550 ft ) cable - stayed bridge across an operational road flyover , and connects several hospitals , tourist attractions , and a major industrial estate along its route . Services are provided at intervals of 5 min . An interchange with the Yellow Line is available at Central Secretariat through an integrated concourse . 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 . The section between Mandi House and Central Secretariat , was opened on 26 June 2014 . After that a 971 - metre section between ITO and Mandi House was opened on 8 June 2015 . The latest addition to the line , an 14 km ( 8.7 mi ) extension southwards till Escorts Mujesar in Faridabad was inaugurated by Prime Minister Narendra Modi on 6 September 2015 . All the nine Metro stations of the Badarpur -- Escorts Mujesar ( Faridabad ) section of Delhi Metro 's Phase 3 , have been awarded the highest possible rating ( platinum ) for adherence to green building norms , by the Indian Green Building Council ( IGBC ) , which has devised a rating mechanism for Metro stations and buildings on a scale of platinum , gold , silver etc. for following the green building specifications . The awards for these stations were given to DMRC 's Managing Director , Dr. Mangu Singh by Dr. PC Jain , Chairperson , IGBC in the presence of DMRC 's directors and senior officials on 10 September 2015 . Currently the Faridabad corridor of Delhi Metro Violet Line is the longest metro corridor outside of Delhi , consisting of 9 stations and the total length of corridor being 14 km . On 28 May 2017 , the ITO -- Kashmere Gate corridor of the Delhi Metro was formally flagged off for passenger services by the Union Minister of Urban Development , Sh . M. Venkaiah Naidu and the Chief Minister of Delhi , Sh . Arvind Kejriwal . This section which runs underground is popularly known as the Heritage Line . Orange Line : Airport Express ( edit ) The interior of a Delhi Metro Airport Express train Main article : Delhi Airport Metro Express 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 . The line was constructed at a cost of ₹ 57 billion ( US $890 million ) , of which Reliance Infrastructure invested ₹ 28.85 billion ( US $450 million ) and will pay fees on a revenue - share model . 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 . Rolling stock consists of six - coach trains operating at intervals of ten minutes and having a maximum speed of 135 km / h ( 84 mph ) . 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 . The line reopened on 22 January 2013 . 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 . In Jan 2015 , DMRC reported that Airport Metro has recorded about 30 per cent rise in its ridership following the fare reduction of up to 40 per cent in July last year On 14 September 2015 DMRC announced to reduce fares even further to improve the ridership of the line , the new fare structure will have maximum fare of ₹ 60 and minimum of ₹ 10 instead of ₹ 100 and ₹ 20 charged earlier , a reduction of about 40 % . DMRC has stated that this was done to reduce the crowding on Blue line , diverting some of the Dwarka - bound passengers to Airport Express Line , which is underutilised and faster compared to the Blue Line . Phase III ( edit ) Delhi Metro map with Phase I , phase II and phase III routes Work on Phase III started in 2011 , with 2016 being the planned deadline , more than 20 tunnel boring machines were used simultaneously to expedite the work , and the actual work was completed in fy2017 - 2018 . Phase - I ( Red , Yellow and Blue lines ) and phase - II ( Green , Violet and Orange lines ) had focused on adding new radial lines to expand the network . To reduce the congestion and improve the connectivity , Phase - III includes 11 extensions to the existing lines as well as building ring lines ( Pink and Magenta lines ) . Phase - III has 28 underground stations , 2 new lines and 11 route extensions , totalling 167.27 km , with a cost of ₹ 350 billion ( US $5.5 billion ) . The expected daily ridership of the whole network of all phases , ater the compleiton of Phase - II , is 4 million passengers . The communication based train control ( CBTC ) is being used which enables trains to run at a short headway of 90 seconds . 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 .

Pink Line & Magenta Line will start at the end of 2017 , however , Gray Line ( Line 09 ) will start in 2018 . DMRCL Phase 3 Network Info . Planned networks ( edit ) 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 ) , Phase II ( 125 km ) , Phase III were completed in 2006 , 2011 and 2017 , respectively , and Phase IV ( with extensions to the existing Red , Green , Pink and Magenta lines as well the addition of a new Moss Green line ) will commence in 2017 and will be completed by 2022 , respectively . A final 370 kilometres ( 230 mi ) route length of 230 kilometres ( 140 mi ) ( Phase I & II ) and 140 kilometres ( 87 mi ) ( Phase III ) was added at the completion of Phase I , II and III . Phase IV plan approved by the Delhi government will add another 103 kilometres ( 64 mi ) between 2017 and 2022 . This makes the total existing and approved route length at the end of Phase IV 456 kilometres ( 283 mi ) long . As of July 2017 , the 29.7 kilometres ( 18.5 mi ) long under - construction Noida - Greater Noida Metro , 4.86 kilometres ( 3.02 mi ) long approved Narela to Kundli ( Sonipat ) and the independently operated existing 11.7 kilometres ( 7.3 mi ) long Gurgaon Metro opened in November 2013 ( interchanges with the Delhi Metro at Sikandarpur station on Yellow line ) add another 46.26 kilometres ( 28.74 mi ) km to the network , bringing the total network length in NCR to 512.26 kilometres ( 318.30 mi ) . This figure is likely to go up as more extensions are approved by Delhi government as part of the Phase IV as well with the additional of more metro routes being independently added in NCR by Haryana and Utter Pradesh governments .

HUDA City Centre metro station Train at HUDA City Centre metro station The trains operate at a frequency of one to two minutes to five to ten minutes between 05 : 00 and 00 : 00 , depending upon the peak and off - peak hours . Trains operating within the network typically travel at speed up to 50 km / h ( 31 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 . Navigation information is available on Google Transit . Since October 2010 , the first coach of every train is reserved for women . However , last coaches are also reserved when the train changes tracks at the terminal stations in the Red , Green and Violet Lines . To make travelling by metro a smoother experience , Delhi Metro has launched its own official app for smartphone users , ( 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 . Security ( edit ) 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 . 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 . 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 . Intercoms are provided in each train car for emergency communication between the passengers and the train operator . Periodic security drills are carried out at stations and on trains to ensure preparedness of security agencies in emergency situations . DMRC is also looking at raising the station walls and railings for the safety of passengers . Ticketing and recharge ( edit ) Delhi Metro Card for Common Mobility 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 ₹ 10 ( 16 ¢ US ) to ₹ 60 ( 94 ¢ US ) . Fares have been revised by DMRC and will be applicable from 10th October , 2017 . Fares are calculated based on the origin and destination stations using a fare chart . A common ticketing facility for commuters travelling on Delhi Transport Corporation ( DTC ) buses and the Metro was introduced in 2011 . Travel cards are available for longer durations and are most convenient for frequent commuters . They are valid for ten years from the date of purchase or the date of last recharge , and are available in denominations of ₹ 200 ( US $3.10 ) to ₹ 2,000 ( US $31.20 ) . A 10 % discount is given on all travel made on it.An additional 10 % discount is given to travel card holders for exiting the metro system in off - peak hours i.e. From start of revenue services to 0800 hours , from 1200 hours to 1700 hours and after 2100 hours to end of metro service in night . This additional discount is given only in Weekdays i.e. from Monday to Saturday . A deposit of ₹ 50 ( 78 ¢ US ) 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 . 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 ₹ 200 ( US $3.10 ) and that of a three - day card is ₹ 500 ( US $7.80 ) , including a refundable deposit of ₹ 50 ( 78 ¢ US ) that must be paid at the time of purchasing the card . Problems ( edit ) Metro station and train entering . As the network has expanded , high ridership in new trains have led to increasing instances of overcrowding and delays on the Delhi Metro . To alleviate the problem , 8 coach trains have been introduced in Yellow line and Blue line and an increase in the frequency of trains has been proposed . Infrequent , overcrowded and erratic feeder bus services connecting stations to nearby localities have also been reported as an area of concern . Ridership ( edit ) Delhi Metro has been registering a continuous increase in ridership since its inception . When Metro services were introduced in 2002 , the average ridership was 80,000 passengers per day . As of FY 2016 - 17 , average daily ridership has risen to 2.76 million , with the latest daily ridership record set on 17 August 2016 . On 4 August 2014 daily ridership crossed the 2.7 million figure . Since then the highest ridership has kept on surpassing the previous best , compelling metro authorities to keep increasing the services on busy routes . Most recent Delhi Metro daily ridership record of 3.3 million passengers was reached on the eve of the Rakshabandhan ( 17 August 2016 ) , when commuters poured in large numbers throughout the day . On 25 December 2014 , it was reported that the ridership of the Airport Express had almost doubled in the past year to almost 600,000 passengers per month now , as compared to just above 300,000 at the beginning of the calendar year . Currently , Delhi Metro has about 220 trains of four , six and eight coaches totalling 1,290 coaches . It is further planning to add 421 more coaches on the existing route before the completion of phase 3 . During the financial year 2015 , DMRC on an average pressed 1,083 coaches in an hour ( during peak hour ) , in 2012 -- 13 , the number was 819 . On an average trains make 2,880 trips per day .
