The Prime Minister, Shri Narendra Modi inaugurated the extension of Delhi Airport Metro Express line from Dwarka Sector 21 to a new metro station ‘Yashobhoomi Dwarka Sector 25.
More Details:
- The new Metro Station will have three subways – a 735m long subway connecting the station to the Exhibition halls, Convention centre, and Central Arena; another connecting the entry/exit across Dwarka Expressway; while the third one connecting the Metro station to the foyer of the future Exhibition halls of ‘Yashobhoomi’.
- He also had a heartwarming interaction with the employees of DMRC who were involved in construction of the section.
- Delhi Metro will also increase the operational speed of Metro trains on the Airport Express Line from 90 to 120 km/hr, thereby reducing the travel time. The journey from ‘New Delhi’ to ‘Yashobhoomi Dwarka Sector 25’ will take about 21 minutes.
- The Prime Minister arrived at Yashobhoomi Dwarka Sector 25 Metro Station via metro from Dhaula Kuan Metro Station.
The Prime Minister’s Office tweeted “All smiles on the Delhi Metro! PM Narendra Modi interacted with people from various walks of life during his journey to Dwarka, to inaugurate Phase-1 of Yashobhoomi convention centre.”
- This historic increase in speed of India’s fastest Metro corridor gradually from 90 KMPH to 120 KMPH has been made possible by meticulous planning and time-bound implementation by DMRC’s engineers in consultation with a number of other government agencies and domain experts.
- To facilitate the movement of the trains at such a high speed, over 2.6 lakh tension clamps were replaced on the entire corridor. The bulk of the work was carried out in the night time from 11 PM till 7 AM to ensure minimal hindrance to the smooth operation of services. Over 100 workers were deployed at a time for this work.
- Before taking up this mammoth exercise, the efficacy of these clamps was checked on a kilometre-long trial track. Various measurements including vibration & stresses on rails were carried out using advanced instruments on this trial track before implementing the same on the main corridor.
- The estimated timeline for the completion of this task was 18 months. However, DMRC took the challenge and successfully ensured the completion of the work within just six months.
- A highly advanced system consisting of 3D accelerometers and strain censors was deployed for continuous measurement of vibrations and strains on the tracks at different speed levels.
- Oscillation monitoring was performed at speeds from 90 KMPH to 120 KMPH to ascertain smooth movement at higher speed levels. Tremendous efforts were put in by DMRC officials to analyse the measurement data at various speeds to understand the behaviour and response of the system.
- The signalling infrastructure also required verification of all software and safety certifications of the main system and the subsystems at such high speed. The interface testing with rolling stock and passenger information systems was also checked in detail.
- The working of the Passenger Screen Doors (PSDs) in coordination with the movement of the train was also done. Extensive testing of all signalling equipment was conducted in a graded manner involving track, rolling stock, traction for over two months.
- The total journey from New Delhi to Yashobhoomi Dwarka Sector-25 will take about 21 minutes. Earlier the travel time between New Delhi and Dwarka Sector – 21 was approximately 22 minutes and now it has reduced to around 19 minutes between these two stations, leading to a saving of 3 minutes.
