Morning rush hour. Delhi Metro drags & drags. Pulls up abruptly outside Yamuna Bank station, again outside Pragati Maidan. takes nearly 30 mins to cover distance it usually does in 10 mins. worst part - you have no one to complain to. Y is DMRC not on Twitter?

Delhi Metro's Blue Line metro services were affected twice on Wednesday due to signalling issues on the different sections of the corridor, officials said. 

A senior Metro official said 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," he said. "Between 3:00 to 3:30 pm, the loss of view was for the entire Blue Line, which created bunching of trains on the entire line," he said. 

The intermittent signalling issue was resolved at 4:23 pm and since then train services were running normal on the entire Blue Line, he said. 

However, the snag recurred at around 7 pm at another section, and many passengers complained of delay in services. The 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."
