New Delhi, December 5: Train services were affected for nearly one and a half hour on the Delhi Metro's Blue Line Wednesday afternoon due to signalling issues on the Karol Bagh-Dwarka section, officials said. The Blue Line connects Dwarka to Noida/Vaishali.

"Train services were affected due to signalling issue (loss of centralised view intermittently) on the Karol Bagh-Dwarka section," a senior official said.

The snag led to bunching of trains, the official said. Delhi Metro Introduces 21 New Trains To Encourage Commuters to Use Public Transport Amid Rising Pollution Levels.

"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," the official said.

As a result, trains were being locally controlled as and when such view loss was happening, resulting into "intermittent bunching/hold up of trains for brief spells".

"Between 3:00 to 3:30 pm, the loss of view was for the entire Blue Line, which created bunching on overall line, before being restored again at 3:30 pm. The intermittent issue was resolved at 4:23 pm and since then train services are running normal on entire Blue Line," he said.
