A speed restriction of 20 km per hour was imposed around 11:20 AM between these stations on the up-line towards Dwarka, a metro official said.
"It was done to address an Over Head Electrification problem. Work is in progress and the restrictions are still there," the official said.
The two branches of Blue Line (Line 3/4), considered snag-prone, connect Dwarka Sector 21 to Noida City Centre and Vaishali.
