Services on a section of Delhi Metro's Pink Line were briefly affected on Thursday evening due to a "minor signalling issue", a senior DMRC official said.
The Pink Line runs between Majlis Park and Shiv Vihar.
"There was a delay in services between Majlis Park and Durgabai Deshmukh South Campus stations of the Pink Line due to a minor signalling issue. Service on all other lines are normal," the official said.
The Delhi Metro Rail Corporation also tweeted the information to alert commuters.
Services resumed after a brief delay.
