Signalling issue hits Metro services on Blue Line for second consecutive day

New Delhi, Signalling issue continued to affect Delhi metro services for the second consecutive day on Thursday on its Blue Line section. 'Owing to the signaling issue which is intermittently surfacing on Yamuna Bank to Vaishali section of Blue Line affecting punctuality of services on entire Blue Line, DMRC has now introduced seamless train movement on the entire Blue line, to provide the best possible frequency till the issue is sorted out by technical team,' a DMRC spokesperson said. The spokesperson said train services between Dwarka and Noida are running seamless in one go with a frequency of around 4 minutes 30 seconds on automatic mode through central control (OCC). Train services between Yamuna Bank to Vaishali section are being run in an dependent loop with a frequency of around 5 minutes 30 seconds through local control. (Station level).

The signaling team is carrying out the rectification work on the system and as soon as it is rectified, train services on entire blue line will be reintroduced as per normal time table, the spokesperson added. On Wednesday afternoon, 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 between Karol Bagh and Dwarka section. 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 1500 to 1530 hrs, the loss of view was for entire Blue line which created bunching on overall Line before being restored again at 1530 hrs. The issue was resolved at 1623 hrs but intermittent signalling issue resurfaced again around 1900 hrs on Wednesday evening.
