Delhi Metro train services on the Blue line to Noida were disrupted today for nearly three hours today due to overhead electrification problem.
There was a problem in an insulator on the overhead electrification between Shadipur and Patel Nagar on the down line en route Noida city centre, a DMRC official said.
"The problem was detected at 1:11 PM and was rectified by 3.12 PM. Due to the technical fault, services had to be run on single line between Kirti Nagar and Patel Nagar in the affected period resulting in delayed running of trains on the entire corridor by eight to ten minutes," he said.
In urban Mass Rapid Metro operations, 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 locate the faulty insulator amongst 200 such insulators, the official said, adding that once it was located, the insulator was replaced within 12 minutes.
"Three repair teams were rushed to the spot from Yamuna Bank, Mundka and Najafgarh depots. During the entire period, centralised and local announcements were also made at all the stations and trains," he said.
However, metro services on all other corridors remained normal.
