The history of planning a Metro Project for Delhi dates back to 70's. The Central Road Research Institute (CRRI) undertook the first exhaustive study on traffic and travel characteristics of Delhi in 1969-70.
By examining several alternatives, it recommended for a Mass Rapid Transit Network for Delhi. Metropolitan Transport Team (MTT), Indian Railways, has reviewed the above schemes.</li></ul>HISTORY<br />
MTT sought for some modifications to recommendations of CRRI and planned for a well knit Mass Rapid Transit System for the capital city of India. The system comprised of 36 Km of underground corridors aligned two axes North-South and East-West Corridors and 96 Kms of surface rail corridors. Metropolitan Transport Project (MTP-R, set up by the Ministry of Railways, Government of India) prepared an engineering plan to construct the MTR system.<br />Delhi Development Authority (DDA) prepared a perspective plan for Delhi (MPD-2001) in 1984 and recommended for a multi modal transport system comprising of 200 km of Light Rail Transit System, 10 Km of Tramway, an extension to surface rail system and extensive road network. The Urban Arts Commission suggested some modifications to the proposal of DDA and recommended for the development of the existing Ring Railway with three radial underground MRT corridors.<br />
Due to rapid growth especially along the western and eastern parts of the city, a study group was appointed by the Ministry of Railways, Govt. of India to recommend a precise alignment for the East-West corridor and in 1987 further appointed a Task Force for assessing the choice of exact construction technology.<br />Feasibility Report on Integrated Multi Modal Mass Rapid Transport System of Delhi (IMMRTS) prepared by RITES recommended for three-component system comprising of Rail corridors, Metro corridors and dedicated bus way totaling to 184.5 Km and further addition of 14 km increased to 198.5 km.<br />The total network contains 16 sections to be implemented in a sequence based on passenger kilometer carried per kilometer length of each section. The first phase of the network, now (commissioned) comprises of 65.11 km of route length with 13.01 km underground called Metro corridor and 52.10 km surface<br />
<ul><li> Has a carrying capacity as high as 60,000 – 80,000 phpdt (peak hour peak direction traffic).
Requires 1/5th energy per passenger km. compared to road – based system.
Causes no air pollution in the city and lesser noise levels.
Occupies no road space if underground and only about 2 metre width of the road, along central median, if elevated. </li></ul>advantages<br />
<ul><li> Carries same amount of traffic as 6 lanes of bus traffic or 26 lanes of private motor cars(each way).
Is more reliable, comfortable and safer than road based system.
Reduces journey time by anything between 50% and 75% depending on road conditions .</li></li></ul><li>The Delhi Metro is being built in phases. <br /><ul><li>Phase I completed 65.11 km (40.46 mi) of route length, of which 13.01 km (8.08 mi) is underground and 52.10 km (32.37 mi) surface or elevated. The inauguration of the Indraprastha–Barakhamba Road corridor of the Blue Line marked the completion of Phase I on October 27, 2006.
Phase II of the network comprises 128 km (80 mi) of route length and 79 stations, with the first section opened in June 2008 and completed in 2010.
Phases III (112 km) and IV (108.5 km) are planned to be completed by 2015 and 2021 respectively, with the network spanning 413 km (257 mi) by then.</li></ul>network<br />
As of February 23, 2011, the whole of Phase-I and parts of Phase-II are complete, with the network comprising six lines with 140 metro stations and a total length of 183.7 km (114.1 mi).<br />Current routes<br />
<ul><li> The Red Line was the first line of the Metro to be opened and connects Rithala in the west to Dilshad Garden in the east, covering a distance of 25.09 kilometres .
Is partly elevated and partly at grade, and crosses the Yamuna River between Kashmere Gate and Shastri Park stations.</li></ul>Red line<br />
<ul><li> The Yellow Line was the second line of the Metro and was the first underground line to be opened.
It runs for 44.36 kilometres (27.56 mi) from north to south and connects Jahangirpuri with HUDA City Centre.
This line also possesses the country's deepest Metro station at Chawri Bazaar, situated 30 metres (98 ft) below ground level.
Interchanges are available with the Red Line at Kashmere Gate station, and with the Indian Railways network at Delhi and New Delhi railway stations .</li></ul>Yellow line<br />
<ul><li> The Blue Line was the third line of the Metro to be opened, and the first to connect areas outside Delhi.
Partly overhead 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.
This line crosses the Yamuna River between Indraprastha and Yamuna Bank stations, and has India's first extradosed bridge across the Northern Railways mainlines near PragatiMaidan.
Interchanges are available with the Yellow Line at Rajiv Chowk station,and with the Indian Railways network at the AnandVihar Railway Terminal .</li></ul>Blue line<br />
<ul><li> Opened in 2010, the Green Line was the first standard-gauge corridor of the Delhi Metro.
The fully elevated line connects Mundka with Inderlok, running for 15.1 kilometres (9.4 mi) mostly along Rohtak Road.
An interchange with the Red line is available at Inderlok station via an integrated concourse.
This line also has the country's first standard-gauge maintenance depot at Mundka.</li></ul>Green line<br />
<ul><li> 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 20.2 km (12.6 mi) long line connects Badarpur to Central Secretariat, with 9 km (5.6 mi) being overhead and the rest underground.
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.
Services are provided at intervals of 2 min 40 sec, the shortest on the network</li></ul>Violet line<br />
<ul><li> 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 is operated, by the Delhi Airport Metro Express Pvt. Limited (DAMEL), a subsidiary of Reliance Infrastructure, the concessionaire of the line.
Rolling stock is expected to consist of six-coach trains operating at intervals of ten minutes and having a maximum speed of 135 km/h .</li></ul>Airport express<br />
FUNDING :-<br /><ul><li> Most recent estimates have placed the cost of construction at 200 crore (US$43.4 million) per kilometre.
30 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 Delhicontributing equal shares.
60 percent has been raised as either long-term or subordinate debt, through soft loans from the Japan Bank for International Cooperation .
The rest of the investment is proposed to be recovered from internal revenues through operations and property development.</li></ul>finances<br />
Revenues & profits<br /><ul><li> One of only five metro systems in the world that operated at a profit without government subsidies.
keeping maintenance costs to a minimum and harnessing additional revenue from advertisements and property development, apart from ticket sales.
The Metro also generates revenue by leasing out its trains and stations for film shoots. Producers have to pay as much as 1 lakh (US$2,170) for every hour of filming, besides a security deposit and insurance</li></li></ul><li><ul><li> Trains operate at a frequency of 3 to 4.5 minutes between 6:00 and 23:00.
Trains operating within the network typically travel at speeds below 80 km/h (50 mph), and stop about 20 seconds at each station.
Automated station announcements are recorded in Hindi and English.
Many stations have services such asATMs, food outlets, cafés and convenience stores. 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.</li></ul>operations<br />
<ul><li> 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.
Intercoms are provided in each train car for emergency communication between the passengers and the driver</li></ul>security<br />
Ticketing..<br />Delhi Metro commuters have three choices for ticket purchase.:<br /><ul><li>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 Rs. 8 to Rs. 30 .
Travel cards - 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 Rs.50 to Rs.800.
A common ticketing facility for commuters travelling on Delhi Transport Corporation (DTC) buses and the Metro will be introduced in 2011.</li></li></ul><li><ul><li>Delhi Metro has reserved coach for women
