The Delhi Metro Rail Corporation (DMRC) on Tuesday said the trials runs on the first section of Phase III – between Central Secretariat and Mandi House – will begin from December 30. Officials said the line will be opened to commuters by March 2014.
The DMRC managing director Mangu Singh said,We decided to start trial runs by December 30 with the intention of opening this section to public by March 2014 which is six months ahead of the original planned date of October 2014. Construction started on this stretch in December,2011.
The construction work on the 3-km underground stretch,which is part of the Central Secretariat-Kashmere Gate line,is almost complete and the trial runs are expected to take place for a couple of months, a DMRC official said.
Officials said the opening of this stretch has been advanced by about six months as it will help in decongesting the Rajiv Chowk Metro station.
Commuters of the Badarpur-Central Secretariat Line,bound for Noida and Vaishali,will be able to change trains at Mandi House. This will save them the hassle of changing trains twice at Central Secretariat and Rajiv Chowk.
The civil engineering,track-fitting,electrification,signalling and telecommunication works are all near completion.
Officials said the Mandi House station will be the first interchange station of Phase III of the Delhi Metro. The station is being expanded to cater to the approximately 70,000 passengers,who are expected to use the station by 2016, an official said.
Checks on the operations will be conducted extensively during the trial runs,officials said.
During the trial runs,the interaction of the train with physical infringements will be checked to ensure that there is no physical blockage to the movement of the train. The entire signalling system will undergo rigorous testing. In addition to this,the response of the train at different speeds and on applying brakes will be checked. The interconnection with the Operations Control Centre will also be monitored during the trials. The behaviour of the track system and the overhead electrification (OHE) will be checked repeatedly during all the trials, the official said.
The OHE system on the Blue Line of the Delhi Metro had
been witnessing repeated snags over the past one year,inconveniencing passengers on several occasions.
