Delhi Metro’s new Yashobhoomi Dwarka Sector 25 station to be operational from Sept 17, 3 pm


In a serious feat, trains will run at a velocity of 120 kmph on the Airport Line of the Delhi Metro from Sunday onwards, officers stated.

This enhance within the velocity of trains on India’s quickest metro hall regularly from 90 kmph to 120 kmph has been made attainable by “meticulous planning and time-bound implementation by DMRC’s engineers in session with a lot of different authorities companies and area specialists,” they stated.

“From September 17 onwards, the Delhi Metro Rail Company (DMRC) goes to function the Airport Categorical Line at an enormous velocity of 120 kilometres per hour,” the DMRC stated in a press release.

Prime Minister Narendra Modi will inaugurate the primary part of India Worldwide Conference and Expo Centre (IICC), named YashoBhoomi, in Dwarka and likewise the extension of Delhi Metro’s Airport Categorical Line from Dwarka Sector 21 to a brand new metro station at Dwarka Sector 25 on Sunday.

The extension of Delhi Metro’s Airport Categorical Line from Dwarka Sector 21 to Yashobhoomi Dwarka Sector 25 will develop into operational from 3 pm onwards on September 17, officers stated on Friday.

Sources on Saturday stated, the improved velocity is prone to be carried out on this line after the inauguration of the extension of the Airport Line.

The present operational Airport Categorical Line spans from New Delhi metro station to Dwarka Sector 21 station.

The entire journey from New Delhi to Yashobhoomi Dwarka Sector-25 will take about 21 minutes.

Earlier, the journey time between New Delhi and Dwarka Sector 21 was roughly 22 minutes, and now it has diminished to round 19 minutes between these two stations, resulting in a saving of three minutes.

The approximate journey time between New Delhi and Terminal 3 of the Delhi Airport will probably be about quarter-hour and 30 seconds. Earlier, it was slightly greater than 18 minutes, the DMRC stated.

To facilitate the motion of the trains at such a excessive velocity, over 2.6 lakh rigidity clamps had been changed on the whole hall. The majority of the work was carried out within the evening time from 11 pm until 7 am to make sure minimal hindrance to the graceful operation of companies. Over 100 staff had been deployed at a time for this work, the assertion stated.

Earlier than taking over this mammoth train, the efficacy of those clamps was checked on a kilometre-long trial observe. Numerous measurements together with vibration and stresses on rails had been carried out utilizing superior devices on this trial observe earlier than implementing the identical on the primary hall, officers stated.

The estimated timeline for the completion of this process was 18 months. Nevertheless, the DMRC took the problem and efficiently ensured the completion of the work inside simply six months, it added.

A extremely superior system consisting of 3D accelerometers and pressure censors was deployed for steady measurement of vibrations and strains on the tracks at completely different velocity ranges. Oscillation monitoring was carried out at speeds from 90 kmph to 120 kmph to establish easy motion at greater velocity ranges, the DMRC stated.

Great efforts had been put in by DMRC officers to analyse the measurement information at varied speeds to grasp the behaviour and response of the system, the officers stated.

The signalling infrastructure additionally required verification of all software program and security certifications of the primary system and the subsystems at such excessive velocity. The interface testing with rolling inventory and passenger data programs was additionally checked intimately, the assertion stated.

“The working of the Passenger Display screen Doorways (PSDs) in coordination with the motion of the practice was additionally achieved. In depth testing of all signalling gear was performed in a graded method involving observe, rolling inventory, traction for over two months,” it added.

Through the non-revenue hours, the overhead gear (OHE) system was additionally made appropriate for the motion of trains at 120 kmph. Ultimately, in spite of everything these efforts, Delhi Metro elevated the operational velocity of Metro trains on the Airport Categorical Line from 90 kmph to 100 kmph on March 22 this yr, the officers stated.

The velocity of the trains was additional elevated to 110 kmph on June 22, which shall be additional elevated to 120 kmph from tomorrow. The protection certification for a similar has already been acquired earlier this month, the DMRC stated.
