The snag occurred when the pantograph, which supplies power from the overhead wire to the train, got entangled in overhead equipment (OHE) of a train between Rajiv Chowk and R K Ashram section, while approaching Rajiv Chowk station at 9.20 am.
As a result, train services were regulated on Line-3 between 9.20 am to 10.05 am in short loop between Yamuna Bank and Noida/Vaishali, between Karol Bagh and Dwarka Sector-21 and in single line between Karol Bagh and Yamuna Bank section.
The stations were witnessing festive rush on the occasion of Bhai Dooj.
