New Delhi, Nov 14 (UNI) The Delhi Metro today carried out trial runs on the 6.3 km stretch between Delhi University and Jahangirpuri in North-West Delhi, about ten months ahead of schedule.
This is the second section of Phase-II which will be opened. It is expected to be opened in December or January 2009.
The section was originally slated to be opened in October 2009.
The trial run began after a small puja was performed at the GTB Nagar Metro Station, said a Delhi Metro spokesman.
The runs were conducted successfully between 1000 hrs to 1700hrs and will continue for about five weeks initially.
This section has five stations of which one is underground (GTB nagar) and four elevated--Model Town, Azadpur, Adarsh Nagar and Jahangirpuri.
Of the 6.36 km stretch, 0.94 km is underground and 5.42 km elevated. The deepest point on the section is 15.30 metres below the surface at GTB Nagar station and the highest point is 16.576 metres above the road at Azadpur station.
The entire signaling system which is based upon Automatic Train Operation (ATO) is also being tested during the trials. The signaling system has been provided by M/s Alstom of France. Apart from this, the radio communication system will also be tested.
During the first three weeks of the trial run, one train set will be used. In the fourth week, two train sets will be used and in fifth week, more train sets will be used as per requirement. Testing will continue round-the-clock.
Telecom, auxiliary power, escalators, fare collection systems, etc. at the stations will also be tested during this period.
Special emphasis will be given on safety which is the prime concern during a trial, as DMRC has to ensure that the system is fully safe for use before the section is opened for the public.
This section will be integrated with the existing 11 km Central Secretariat to Vishwavidyalaya section (Line 2) and will require special focus on integration and extension of the existing signaling system to the new section.
