PM Modi's idea to convert railway coaches into isolation wards, says Piyush Goyal

"It was Prime Minister's idea even before lockdown. One day he called me and asked me whether railway coaches can be converted into isolation wards. I was taken aback. I had not even thought about it. It was an innovative idea that the Prime Minister came up with. Railway employees worked hard and developed the entire design in consultation with the Health Ministry," he said.
