Trains are being made to run on restricted speed due to track circuit drop (signalling issue) at Dwarka, a recurring snag on this corridor.
"Train services on Line 3 are having minor delays due to signalling problem (TC Drop) at Dwarka approaching platform from Noida/Vaishali side.
"Due to this trains are crossing the TC drop area in manual mode with restricted speed leading to bunching," a DMRC official said.
Blue Line or Line 3 connects Dwarka to Vaishali across the Yamuna. Another arm of the line branches off from Yamuna Bank Station towards Noida.
