New Delhi, Feb 21 : Train services on Delhi Metro's Blue Line (Dwarka sector 21-Noida City Centre/Vaishali) were affected for close to 30 minutes on Wednesday due to signalling issue at two interlocking stations, the DMRC said.
"Due to signalling issue at interlocking stations of Subhash Nagar and Rajouri Garden of Line-3, train IDs were lost around 12.30 p.m.
for trains falling in this zone, resulting in delays as they were locally controlled," Delhi Metro Rail Corporation (DMRC) said in a statement.
"Central control for these two interlocking stations was restored at 1 p.m.
and trains are now being regularised as per normal IDs," the statement added.
