A technical snag,which lasted over an hour,brought Delhi Metro services on the Blue Line to a standstill on Monday afternoon.
Senior DMRC officials said that a problem with the overhead electrification system between Patel Nagar and Shadipur stations on the Noida-Dwarka line led to disruption in services. The
Platforms at three Metro stations had to be vacated,resulting in commuters having to find other ways to reach their destinations. A huge rush at the Rajiv Chowk station,which is the primary interchange station on the Blue line,also ensued.
DMRC officials said,Metro rail services were affected on the Blue line due to a problem in an insulator on the over head electrification (OHE). The problem started at 1.11 pm and was rectified by 3.12 pm. During the affected period,trains had to be run on a single line between Kirti Nagar and Patel Nagar,resulting in trains getting delayed by eight to 10 minutes.
Officials said once the insulator was identified,the problem was rectified in 12 minutes. Overhead electric supply poles are located at a distance of 40 metres with two insulators on each OHE mast. The Metro electrical engineers had to find the faulty insulator from among 200 such insulators. Three repair teams were rushed to the spot from the Yamuna Bank,Mundka and Najafgarh depots, an official said.
Rahul Jain,a commuter,said: The train was running very slowly. When it reached Shadipur,we were asked to vacate the coach. Soon,another announcement was made asking everyone to vacate the platform,or board another train which travelling in the opposite direction. I had to take an auto to my office in Connaught Place and was delayed by over an hour.
