Metro gives preview of Badarpur line, trial runs in July
New Delhi: Come September, the Central Secretariat station will have an additional underground station for DMRC`s standard gauge network, making it the only installation in the world to operate two different gauges.
Giving a preview of the new station, the Delhi Metro Rail Corporation announced that the trial runs of the Central Secretariat- Badarpur Standard Gauge line will begin in the
first week of July from Central Secretariat to Lajpat Nagar.
The 22km-corridor connecting Central Secretariat with Badarpur, which is close to Haryana, is scheduled to be opened by September, a month before the Commonwealth Games.
The new underground station being constructed will be linked to the existing Central Secretariat station, which is a broad gauge network, and will act as a point for
passenger interchange once the Badarpur corridor opens. Currently, it is a terminal station.
"The existing station is being integrated with the new one by cutting the walls of the existing functional station and amalgamating with the new one, providing access between
the concourse and the platform levels of the two stations," Kumar Keshav, Director (Project&Planning), DMRC, said.
Simply put, once the Bararpur line commences, the Central Secretariat station will be one and passengers of both Line 2 (Jehangirpuri-HUDA City Centre) and Line 6
(Central Secretariat-Badarpur) can change trains without having to get out of the station or even the platform.
Briefing journalists at the station, where almost 700 people were racing against time to finish the work, Kumar said it was a very difficult and challenging task for the engineers
as they had to evacuate tunnels at a depth of 17 metres that runs through the Lutyen`s Zone.
"It is even more challenging that the new station was built without disturbing the existing one and the train operations. Even the road traffic on the busy Rail Bhawan road
was not disturbed," he said.
DMRC spokesman Anuj Dayal said once the new station gets ready, the Central Secretariat station will be the only one in the world where two different gauges - broad and standard - will be operational.
Engineers at the site said a total of 35 metres length of the main wall of the operating station was cut and designers had projected that 10,5000 kg of load has to be supported when the wall is being cut.
They said the wall was being checked everyday thrice at the station and utmost care was taken not to disturb the people and traffic.
"This is a big challenge as the entire depth from the roof slab to the base slab has to be supported inside the wall in the existing station before cutting the wall for interconnection," Dayal said.
Passengers of both the Lines -- 2 and 6 -- will find a common concourse where they can purchase token/smart cards and there will be a total of 6 entrances which will connect both the stations.
