The Green Line[2][3] of the Namma Metro is part of the mass-transit rail system for the city of Bangalore, India. It will consist of 25 stations from Nagasandra to Puttenahalli under Phase I. When Phase II is completed, it will stretch from BIEC in the north to Anjanapura in the south. The line will measure 24.20 km and will be mostly elevated, with some stations underground. The opening of this line has been delayed several times, due to difficult tunnelling conditions. However, the stretch between Sampige Road to Kempegowda will be opened to the public by August 2016. The southern stretch of the line, will however be operational by December 2016, thereby completing the entire Phase I project. [4] The line connects the northern, central and the southern areas of Bangalore. Currently, only a 13.30 km northern stretch, from Sampige Road to Nagasandra is operational. [5]

The detailed project report (DPR) for Phase I, comprising the Purple and Green Lines, of the Namma Metro project was prepared by the Delhi Metro Rail Corporation (DMRC) and submitted to the BMRCL in May 2003. The final approval on a scheme that incorporated the expertise of DMRC and RITES Limited did not come until April 2006.[8] The DPR prepared by DMRC envisaged a 33 km (21 mi) elevated and underground rail network with 32 stations for Phase I of the project. The proposed gauge was standard gauge unlike the broad gauge on the Delhi Metro network. The rationale for the metro includes reduced journey times, cutting fuel use, accident reduction and lower pollution.

Construction work for Phase I of the Namma Metro project was scheduled to start in 2005 but was delayed by a February 2006, due to change of government in Karnataka and continued debate over whether the project was financially feasible and appropriate for the city. The Union Cabinet approved Phase I of the Namma Metro on 25 April 2006, when it was estimated to cost ₹5400 crore (US$800 million). The cost escalated to ₹13845 crore (US$2.1 billion) as various problems delayed the completion of the project.[9][10][11] Land acquisition for Phase I of the project cost ₹2500 crore (US$370 million).[9] BMRCL secured ₹6500 crore (US$970 million) through long-term loans and ₹300 crore (US$45 million) by selling bonds, while the remaining project cost was funded by Central Government and the State Government. BMRCL secured loans from several agencies - ₹3000 crore (US$450 million) from the Japan International Cooperation Agency (JICA), ₹600 crore (US$89 million) from the Housing and Urban Development Corporation Limited (HUDCO), ₹25 crore (US$3.7 million) from the Asian Development Bank (ADB), and the rest from a French lending agency. Approximately 10% of the ₹6500 crore must be paid as interest by the BMRCL every year. The Federation of Karnataka Chambers of Commerce and Industry estimated that this amounted to an interest payment of ₹2 crore (US$300,000), however the BMRCL refuted the claims that the interest was that high, while confirming that it was "definitely more than ₹1 crore (US$150,000) per day."[9]

The foundation stone for the Phase I construction was laid by Prime Minister Manmohan Singh on 24 June 2006.[12] Construction on Reach 3 and 3A of Phase I of the Namma Metro began in 2009-10. The total cost of the project on this stretch was ₹2,100 crore.[13] The underground work commenced in May 2011. Each corridor consists of two tunnels which are the first underground tunnels built for trains in South India. The tunnels, dug using tunnel boring machines (TBM), are located approximately 60 feet below ground level, have a diameter of 5.5 metres and are 5 metres apart. Four TBMs, nicknamed Helen (TBM 1), Margarita (TBM 2), Kaveri (TBM 3) and Krishna, were used for tunnelling work on the Green Line.[14][15][16][17][18][19] A trial run was conducted on 8 August 2013.[20]

Construction of the stretch required 1.3 lakh tonnes of concrete, 44,500 tonnes of steel bars, and 190 km of high tension wires weighing 2900 tonnes. A total of 395 piers, including station piers and portals, were constructed on the stretch. The tallest pier of the viaduct is a 21-metre pier between Kuvempu Road and Sriramapuram stations, opposite Gayatri Devi Park. There 353 spans on the stretch, the longest being the 66 metre curved span over the railway track off Sriramapuram. The total roofing area of the 10 stations on the stretch was 47,000 square metres.[21]

The line was opened to the public on 1 March 2014.[22] BMRCL Managing Director Pradeep Singh Kharola stated that about 25,000 passengers travelled on the line on opening day.[23] Civil works had not been completed at Peenya Industry and Peenya stations, among others. These were covered up by paintings, and work was expected to be complete in another two months.[24] In the first month of operations, 7.62 lakh people at an average of 24,605 people daily used the line, generating a revenue of ₹1.5 crore (US$220,000).[25]

Tunnel boring machine, Godavari, began drilling the 970 metre underground stretch between the Sampige Road and Majestic stations in April 2014. Godavari broke down a few months later, and needed to have its cutter head replaced. According to the BMRCL, the machine broke down due to tough terrain including hard rock and boulders. The cutter head had to be imported from Italy. The machine restarted work in September 2015. Godavari completed drilling and emerged on the Majestic station end of the tunnel on 19 April 2016..[26] Meanwhile, Kaveri and Krishna were drilling the underground stretch between National College and Majestic station. As of April 2016, Kaveri and Krishna had about 100 metres and 250 metres of drilling left to complete, respectively.[27]

Stations

There are 25 stations on the Green Line. 13 stations, from Nagasandra to Sampige Road are there, as of now. Each station has around 60 surveillance cameras. 36 passenger lifts and 52 escalators are built on the 13 stations of Reaches 3 and 3A.[21]
