Metro services were hit till 7 a.m. on Thursday

Metro services on the Purple Line were disrupted for the second consecutive day on Thursday after Bangalore Metro Rail Corporation Ltd. officials found a ‘honeycomb formation’ or concrete distress in a beam above a pier near Trinity station.

“To facilitate the work near Trinity station, a decision was taken not to operate services from M.G. Road to Baiyappanahalli till 7 a.m. Train services were normal after that. We are trying our best to operate trains even in morning hours for coming days,” said a BMRCL official. As planned, trains were running at slower speed for distance of 260 m from M.G. Road to Trinity, and this affected the frequency of trains on the line.

The BMRCL has also decided to increase the frequency of inspection of civil structures on Phase I. “Usually, structural inspections are done once a year or once in two years. We are in the process of reviewing the frequency of inspections,” said officials.

After Wednesday’s incident, the BMRCL received a “panic alert” from the public claiming that another crack had appeared in a metro pillar near Baiyappanahalli. BMRCL officials, after an inspection, allayed fears. “After receiving the photo of the pillar, a spot inspection was conducted. The pillar has not developed any cracks,” said Ajay Seth, managing director of the BMRCL. He added that the visible gap above the metro pillars is not a structural flaw, but a part of the design.

The BMRCL’s decision to abandon normal train services on Wednesday till 10.20 a.m. did not make much of a dent on the ridership, which stood at around 3.88 lakh. “There was no drop. What was recorded was more than the average ridership,” said an official. The BMRCL drew flack from commuters for failing to alert them in advance about the change in schedules or notify passengers of the problem.
