Services on the Delhi Metro‘s Blue Line connecting Dwarka to Noida/Vaishali were affected due to signalling issues on the different sections of the corridor.
According to a senior Delhi Metro official, ” The first technical snag occurred around 3 pm. Train services were affected due to signalling issue (loss of centralised view intermittently) on the Karol Bagh-Dwarka section.
“The view and control of the signalling and Automatic Train Control system on Blue Line (Dwarka Sec-21 to Noida City Centre/Vaishali) at Operations Control Centre (OCC) was intermittently getting lost today between Karol Bagh and Dwarka section,” he said.
He added,”Between 3:00 pm to 3:30 pm, the loss of view was for the entire Blue Line, which created bunching of trains on the entire line.”
He claimed,”The sporadic issue was resolved at 4:23 pm and since then train services were running normal on the entire Blue Line.”
The snag, however, recurred at around 7 pm at another section, and many passengers complained of delay in services.
A DMRC official said, “Train services on Blue Line are available at a frequency of 5-8 minutes due to intermittent signalling issues which resurfaced at around 7 pm.”
