Delhi Metro commuters on Thursday had to wait longer due to slow movement of trains on its Blue Line. "
Slow movement of trains between Dwarka Sector 9 and Dwarka Sector 21. Normal service on all other lines," the Delhi Metro Rail Corporation (DMRC) said in a tweet.
There was also a brief delay in metro services on DMRC's Blue Line on Wednesday morning due to a signalling issue.
The Blue Line of the Delhi Metro Rail Corporation connects Dwarka in Delhi to Electronic City in Noida.
