Metro services on the entire Magenta Line were affected on Tuesday due to a technical snag on the section between Shankar Vihar and Terminal 1 IGI Airport, officials said.
The 34.2-km Magenta Line connects Botanical Garden and Janakpuri West stations.
"Due to some technical issues, services between Shankar Vihar and Terminal 1 IGI Airport have been affected and train are being run at restricted speed in this stretch," a senior DMRC official said.
Due to this, there was bunching of trains, affecting services in rest of the corridor too, he said.
A restricted speed is about 30 kmph, and trains' regular plying speed is about 40 kmph, the official said.
