The 45-km long line, from Jehangirpuri to Gurgaon, is expected to have a very high ridership.

As per the Detailed Project Report (DPR) for the line, the opening of the new section will add around 3.4 lakh commuters to the Line 2 (Central Secretariat to Jehangirpuri) by the year 2011. Since the section is already crowded, DMRC has taken a decision to add about 60 more trains to the line when the Gurgaon stretch becomes operational.

``Once the Gurgaon corridor is opened for the public, it will form an approximately 45-km long Metro line connecting parts of north, south Delhi and Gurgaon. Journeying from the one end to the another will take just 90 minutes. DMRC is planning to run around 60 trains on this line with a frequency as high as 3 minutes, benefiting lakhs of passengers,'' said a DMRC spokesperson. Trains on the Noida section run at a frequency of 8-11 minutes during off-peak hours.

The Gurgaon line also has the sharpest broad gauge curve with a radius of 282.5 metres near IFFCO Chowk. The other curves on elevated Metro tracks have a radius of over 300 metres. The spokesperson added curves of less than 300 meters radius are considered sharp curves in urban rail construction. ``This had to be done near IFFCO Chowk to as the area is very congested and we wanted to retain the already existing buildings, commercial malls and residential complexes on either side of the Metro alignment along Mehrauli-Gurgaon (MG) road. The alignment was also planned along the median so that people benefit from it,'' the spokesperson said.
