Unlike in New Delhi, the Metro services are not restarting operations in Kolkata today as part of Unlock4. In fact, West Bengal is on a total lockdown today. Nothing but essential services can function. The number of daily new Covid19 cases in Kolkata have declined and the state is recording a surge of around 3,000 Covid cases a day. Containment zones in Kolkata have also declined dramatically from 338 in mid-May to just one, which is in north Kolkata.
