DMRC Starts Trial Runs on Magenta Line’s Janakpuri – Airport Section

After airlifting, offloading and coupling 6 coaches together at Sadar Bazar, the Delhi Metro Rail Corporation yesterday launched trial runs on the 10 km Janakpuri  West – Terminal 1 IGI Airport section of the Delhi Metro’s 38.23 km Magenta Line. This is the 2nd stretch of the line where trial runs have started, with trial runs underway on the 12 km Botanical Garden – Kalkaji in the other end of the city since October 27, 2016.

As per a press release:

During these trials, the interface of the Metro train will be checked to ensure that there is no physical infringement with civil infrastructure during the movement of the train on the track and also testing of various subsystems of coaches shall be done.  Later on, in stages, the new signaling technology to be implemented on this corridor, the Communication Based Train Control (CBTC) will also undergo rigorous testing. The response of the train at different speeds, braking of the train and the interconnection with the Operations Control Centre (OCC) will also be monitored during the trials. The behavior of the track system and the Over Head Electrification (OHE) will be checked repeatedly.

The section between Janakpuri West – T1 IGI Airport consists of 5 underground and 1 elevated station at Janakpuri West (interchange with Blue Line), Dabri Mor, Dashrathpuri, Palam, Sadar Bazar Cantonment (elevated) and Terminal 1 – IGI Airport. From a construction perspective, this section was built by 3 contractors:

CC-34 – Janakpuri West to Palam by HCC-Samsung JV
CC-32 – Palam to Shankar Vihar by ITD-ITD Cem JV
CC-29 – West Ramp to Sadar Bazar Cantonment to East Ramp by Afcons Infrastructure

With the commencement of trials on this section, now about 23 kms out of 38 kms of route-length are undergoing trial runs with interior finishing works taking place side by side. Now only the commencement of trial runs on the 15 km ‘mid-section’ of the line, between the T1 Airport – Kalkaji, is pending. The last TBM breakthrough on that section was achieved on November 28 at Munirka Station, and it’ll take at least another 6 months for trial runs to begin.

    In phase 3 platform can only accommodate 6 coach trains or any provision for 8 coach trains as well

      All stations are 140m long and can accommodate a max of 6 coaches where each coach is 22m long. Their game plan is operate trains on a very high frequency thus negating the need for longer trains or more land for stations.

    As per dmrc ,it will not take another 6 months for whole line trial as track laying is near to complete on last & only pending section between vasant vihar & munirka and that is also of one side only.
    Wats ur opinion on this.

      Hi, the DMRC cannot always be trusted. Track-work on other sections is also pending. See a recent image from inside the GK station here. More general images from the station can be found here.

      Besides that, the subcontractors also need to complete installing other sub-systems (electrical, signalling, telecom) before any proper trial runs on the line can start.

    So wats the benefit of doing separate trial of this stretch as the same will not have any approach to depot & can be made operational only after remaing section complete.

    • TMRG says:

      Hi, benefit includes testing out all the subsystems & physical infra to make sure they are configured correctly prior to commencing operations. Initially they’ll test/observe the train’s performance with the physical infra, then move on to the track-system, then to the electrical system and finally onto the CBTC signalling system whenever the Airport-Kalkaji section is ready.

      Hi Nadeemur,
      (1) Nope. All TBMs on that stretch are out.
      (2) Track and subsystem installation work is pending. Whenever that is complete, they’ll begin trial runs.

    What is the point of starting trials between Janakpuri West and Airport if the section can’t be made operational until it has connectivity with the depot?

    Reply
    • TMRG says:

      To save time! The testing phase can take anywhere from 3-5 months, so why wait until the rest of the line is ready? This way, later on they’ll just have to perform testing on the Airport – Kalkaji section followed by a final round of comprehensive tests on the entire line.

    Is it possible that dmrc will commence janakpuri-igi section separately with 2-3 trains as interchange facility b/w to & fro is available on igi.

    Reply
    • TMRG says:

      They can’t start operations as the signalling system can only go live after the airport – Kalkaji section is also live. Without the depot, operation and maintenance will be a nightmare, so it’s better to wait.

      Btw this line will not be connected to the Airport Express (Orange Line) at IGI. They’ll cross over each other (as shown in the maps above), but won’t have an interchange.

      March opening for Botanical Garden – Kalkaji section sounds about right. Maybe next month they’ll invite the CMRS to conduct a safety inspection? Let’s see.

    Have they not provided an interchange with Palam Railway station on this line? it’s too bad if they have not. Lack of sufficient interconnections with railways has been one of the weak points of delhi metro, and has prevented and integrated public transportation system

    Reply
    • TMRG says:

      Multi-modal integration isn’t DMRC’s forte. The metro station is 1 km away from the railway station, so no easy interchange facility is available here like at so many other places.

      • Avneet Nigam says:

        True that, similar situations exist at Kishanganj-Pratap nagar, tughlakabad, Patel nagar- Satguru ram singh marg etc.

        They should really take it seriously though,

    The original plan of starting the Megenta Line on phased manner was in March 2017. But nothing is happening. I was eagerly waiting for the line from Palam to IIT Gate which helps me to my work place. With the delay, I will have the night-marish experience of travelling by bus which really eats away my time. Any solace from Delhi METRO? Srinivasan

    I had written many emails to DMRC for connectivity within Dwarka to Sector 21 for the Airport Express Line, but no concrete outcome received. It is a stupidity for a person to take a rickshaw to sub-city metro line (within Dwearka) travel upto Sector 21 and again travel to your destination. I also find there is no proper way of commuting from Shivaji Stadium to North Block (where Home & Finance Ministries are located). When you will wake up Delhi Metro?

    Delhi Metro is surviving because of traffic snarls/jams on city roads. If the roads are free, the DTC/Cluster will give the Delhi Metro a run for their money
