The Delhi Cabinet on Monday gave "in principle" approval to the Metro project between Central Secretariat and Badarpur.
The government, however, was not satisfied with the ridership projection given by the DMRC and the financial implications and has asked it to explain these in details.
The 20.16 km corridor, with 5.16 km underground and 15 km elevated stretch would have 15 stations. The Central Secretariat and Khan Market and Lodhi Colony stations would be underground whereas JLN Stadium would be at ground level and other 11 would be elevated. The project would cost Rs 4,012 crore at the time of completion.
Chief Minister Sheila Dikshit said, "We have given in principle approval. The Empowered Group of Ministers would now go into the details before the project starts."
The Detailed Project Report (DPR) of the DMRC justified the project saying there would be a huge traffic demand in central and south-central parts of the city in view of the Commonwealth Games.
“This will create an excellent legacy to meet the travel demands of the population of Delhi that would buttress the claim of Delhi to hold the Asian Games in the city in 2014,” the DPR said.
The Cabinet note on the issue suggested financing model used in Phase I of DMTC (approximately 60 percent loan from Japan Bank for International Cooperation).
It, however, said that the financial implication for Delhi government would depend on the exact quantum of JBIC loan. If JBIC loan of 60 per cent of the project cost were not available, the remaining amount would be raised locally.
The entire stretch would use standard gauge (1435 mm) on techno economic considerations and since this is the international practice. In the existing corridors of Metro, broad gauge (1676 mm) has been used.
The DMRC claimed that the standard gauge is better than broad gauge as it consumes 5 per cent less power, decreases cost of the coaches and saves on civil engineering cost.
The traffic forecast of the DMRC said that 3.60 lakh passengers would use the stretch per day in 2011, 4.27 lakh in 2015 and 5.06 lakh passengers in the year 2021. The average speed would be 37 kmph while the maximum speed would be 80 kmph. The maintenance depot would be located at Sarita Vihar.
After crossing the JLN Stadium station at the ground level, the first over ground station would be Lajpat Nagar, followed by Moolchand, Kailash Colony, Nehru Place, Kalkaji, Okhla, Jasola, Sarita Vihar, Mohan Estate, Tughlakabad and finally Badarpur on Haryana border to Faridabad.
