Metro Coached for Central Secretariat Badarpur Line Installed on Lines

In a first-of-its kind operation, DMRC successfully unloaded four coaches on the Central Secretariat (CTST)-Badarpur line near Lajpat Nagar on Saturday night. This special operation was undertaken to expedite the work on Line 6 which got delayed by five months due to the pillar collapse in Zamrudpur last year that is scheduled to start in September this year.

In this unique operation, cranes were used to lift the coaches (each weighing 42 tones) and place them on the inclined tracks. Within six hours, DMRC officials lowered four coaches on the track. ‘‘We had to do some streetscaping near the ramp in order to ensure smooth shifting of the coaches. We have been planning this operation for the past six months and as it was being done for the first time we were very careful during its execution,’’ said Dayal.

The operation was a great engineering achievement as the coaches were stabled on an inclination of about 4%. Generally, the rail coaches are stabled on a straight surface. ‘‘For this, two battery operated shunters were used to prevent the coaches from sliding down backwards on the incline. After being unloaded, the coaches were taken to the Lajpat Nagar Metro station where coupling will be done. Trials on this section are expected to start after the signaling work is complete,’’ said Dayal.

The decision to lower the coaches at the ramp between Jangpura and Lajpat Nagar was taken as the stretch between CTST-Lajpat Nagar is ready for trial run. But as construction work is still going on between Lajpat Nagar-Badarpur, getting the coaches from Sarita Vihar Depot where coaches are parked was impossible.

‘This exercise will save us a month. The work on the stretch between Lajpat Nagar-Badarpur will take some time. But as the stretch between CTST-Lajpat Nagar is ready we wanted to test it and get the signaling system in place. That’s why; we decided to lower the coaches on this stretch. We will extend the trial till Nehru Place once that stretch is ready,’’ said Anuj Dayal.

The carriageway between Lodhi flyover and Moolchand flyover was close for six hours on Saturday night. But as the Lodhi flyover was not barricaded initially, a lot of people had to take a U-turn after getting down the flyover.
