In December 2015, I shared an official map & plan of what Delhi Metro’s 103.93 km Phase 4 project would look like. That plan has now been modified to a slightly smaller 95.86 km project with multiple changes across key metro lines.
Last week during the multiple TBM breakthroughs at the Mayapuri Shaft & Lal Qila station, I got my hands on a document in which DMRC’s Managing Director has approved survey & preliminary ‘pre-construction’ works on all lines that are currently on the table for Phase 4. These lines have been assigned to different Chief Project Managers (CPMs) with orders to immeadiately start survey & other assorted preliminary works on their allocated corridor. Here’s the document:
Here’s a list of all the corridors that are on the table:
New Lines – There have been major alignment changes here
Note: I have assigned random line colors to each corridor to highlight them on the map below.
• Dwarka – Kanjhawala – Prem Piao: 18.6 km with 18 stations
This is a new line that has been added to the mix. Interestingly both Kanjhawala and Prem Piao do not fall on the route of the new Urban Extension Road (UER) # 2 that is being built to urbanize the north-western part of rural Delhi.
• Tughlakabad – Saket – IGI Terminal 1: 19.68 km with 15 stations
This line was earlier envisaged to connect with the Aerocity station, but will now go on to meet the Terminal 1 station with connections at Tughlakabad with the Violet line, Saket with the Yellow line, possibly the Aerocity station of the Airport Express line and finally the Magenta line’s Terminal 1 station.
• Majlis Park – R.K. Ashram: 10.72 km with 10 stations
This line is a truncated version of the Janakpuri W – R.K. Ashram extension of the Magenta line that was planned to come up in Phase 4. With the Janakpuri W to Majlis Park component gone, this corridor will now function as a new stand-alone line with connections to the Blue line at R.K. Ashram, Green line at Nabi Karim, Yellow/Pink line at Azadpur and the Pink line at Majlis Park.
Extension of existing lines – There have been no changes to the alignment
• Pink line – Majlis Park – Maujpur: 12.56 km with 6 stations
One of the following 7 stations has been dropped: Burari Crossing, Jagatpur Village, Surghat, Khajuri Khas, Bhajanpura, Yamuna Vihar and Maujpur
• Green line – Inderlok – Indraprastha: 12.57 km with 10 stations
Stations on this corridor include: Inderlok, Dayabasti, Sarai Rohilla, Ajmal Khan Park, Nabi Karim, New Delhi, LNJP Hospital, Delhi Gate, IG Stadium and Indraprastha
• Red line – Rithala – Narela: 21.73 km with 16 stations
Stations on this corridor include: Rohini Sector 26, Rohini Sector 31, Rohini Sector 32, Rohini Sector 36, Rohini Sector 37, Barwala, Put Khurd, Bawana Industrial Area – 1, Bawana Industrial Area – 2, Bawana, Bawana JJ Colony, Sanpath, New Sanath Colony, Anaj Mandi and Narela
Based on the above, here’s a preview of how all 6 corridors might look like:
Phase 3’s construction is expected to end in 2018 after/during which Phase 4’s tendering process will begin. By then, multiple changes in scope, alignment and design are expected to take place, so there’s nothing to be alarmed about. One of those changes in scope would include the addition of a new corridor connecting Dwarka with Gurgaon for which the DMRC was recently tasked to prepare the Detailed Project Project. Whether this will be an extension of the Airport Express line or the Blue line is yet to be seen. There’s still a long, long way to go before Phase 4’s plans are finalized.
