Signalling Tests Start on Delhi Metro’s Pink Line

Engineers from Bombardier Transportation and Delhi Metro Rail Corporation (DMRC) on Friday started comprehensive signaling tests (trials) on a 20 km stretch between Durgabai Deshmukh South Campus Station and Majlis Park Station of the upcoming 58.59 km Pink Line which’ll eventually connect Majlis Park with Shiv Vihar in the 162.5 km Phase 3 project.

The Pink Line (Line-7) is equipped with Bombardier Transportation’s CITYFLO 650 communications-based train control (CBTC) signalling solution which enables Delhi’s new Hyundai Rotem trains to be operated on both the unattended “driverless” and automatic train operating (UTO and ATO) modes. The contract for that was awarded by the DMRC in September 2013 with a value of Rs. 390 crore.

The DMRC commenced manual testing on a small 6.5 km portion of the line between Shakurpur and Mayapuri in June, and then extended testing further south to South Campus (Dhaula Kuan) in August. This 20 km section includes 12 stations (8 elevated and 4 underground) at Majlis Park, Azadpur, Shalimar Bagh, Netaji Subhash Place (interchange with Red Line), Shakurpur, Punjabi Bagh West, ESI Hospital, Rajouri Garden (interchange with Blue Line), Mayapuri, Naraina Vihar, Delhi Cantonment and South Campus –

As per the DMRC’s Press Release:

These trials will test maximum automation of the new Metro trains, equipped with Unattended Train Operations (UTO) and the new age CBTC (Communication Based Train Control) signaling system which will enable the movement of trains with a frequency of about 90 to 100 seconds, thus significantly enhancing the carrying capacity of the Delhi Metro system. The train will run on the UTO mode to check how the new trains are coordinating with the new signaling technology. This is also the first time that such a long section is being tested in one go. With the commencement of trials today, regular trials will also begin through Delhi Metro’s highest point at Dhaula Kuan at a height of 23.6 metres (as high as a seven storey building).

Interestingly, the DMRC has for the very first time officially acknowledged the tunneling issues faced by the CEC-CICI JV team (Package CC-04) which disabled access from the depot to the rest of the line and directly led to delays in starting tests  –

Another major challenge encountered on this stretch was at Rameshwar Nagar, where a mid shaft had to be created to retrieve four Tunnel Boring Machines (TBMs) since two TBMs got stuck in 2014 due to unexpected rocky terrain. The shafts were created in an extremely congested area.

          Progress of civil works upto July 2017 is 94.01 percent. The line is planned to be opened in stages by March-18(except Trilokpuri to Mayur Vihar Pkt-1 section due to land issue at Trilokpuri).The section Majlish Park to Drgabai Deshmuk South Campus is expected to be completed by Dec-17 and sections Drgabai Deshmuk South Campus to Mayur Vihar Pkt-1 and Trilokpuri to Shiv Vihar is expected to be completed by March-18.

            All –

            Tests have just started. Let’s see what challenges crop up. Nippon had a tough time syncing the PSDs. I’m hoping Bombardier doesn’t face the same issues.

            December is tough.The interchange FOB connections are not in place at NSP, Rajouri or even at Dhaula Kuan.

            If you’ve followed DMRC’s site, you’d know that even the March target shouldn’t be taken seriously.

          • Aakash Yadav says:

            The FOB on Rajouri Garden metro station will be completed soon,because the piller works of FOB is almost near completion.

      Project requires the state government’s cabinet approval. Even if approved in its current form, the central government will ask them to rework so that it aligns with the requirements of the new metro rail policy.

      I haven’t seen bids for Siraspur Station being invited. Interestingly the DMRC has already updated their route maps within the trains.
