Services on the Delhi Metro's Dwarka-Najafgarh corridor were on Friday delayed for over an hour due to a technical glitch, officials said.
The 4.2-km Grey Line connects Dwarka to the urban village of Najafgarh.
"There was a delay in services on the Grey Line due to a technical issue in a train. But, services were normal on all other lines," a senior DMRC official said.
The Delhi Metro also tweeted to alert the passengers.
Nearly 80 minutes later, the DMRC informed passengers that normal services had been resumed.
