Chennai Metro Rail has removed at least 50 roof tiles from all the underground stations in the city, which they suspect are likely to fall, sources said.
This comes days after an incident where a roof tile at Shenoy Nagar Metro station fell over a passenger’s head and injured her.
According to officials of Chennai Metro Rail Limited (CMRL), they started an inspection soon after the accident to see how many stations have such tiles.
“We have gotten rid of over 50 tiles in almost all underground stations, which we thought were prone to fall. But we won’t replace them with another round of fresh tiles; instead we may fill it up with concrete and paint that space,” an official said.
Of late, like the Chennai airport, Chennai Metro stations too have witnessed falling roof tiles.
A few weeks before the incident in Shenoy Nagar Metro station on October 29, another tile collapsed at the Egmore Metro station. But no one was injured.
Officials refused to comment on why the roof tiles were crashing. Sources said that it was because of shoddy construction and poor workmanship. “First of all, it was a bad idea to have tiles fixed at such a height. There should have been some thought on what will happen in case it falls on a passenger,” a source said.
Apart from tiles, a few glass panels have also cracked in some underground stations, including Nehru Park and Pachaiyappa’s College.
Tapping solar power
Meanwhile, CMRL has installed rooftop solar photovoltaic power system in four underground stations — Thirumangalam, Anna Nagar Tower, Anna Nagar East and Shenoy Nagar — according to a press release.
The 103 kWp power system in the ancillary buildings of these stations will generate 13,800 units per month and save CMRL ₹6,34,744 per year.
