Commuters travel in a Metro train as Delhi Metro resumed operations in a graded manner on Monday.

The largest Metro rail system in the country reopened more than five months after it shut its doors to commuters because of the Covid-19 lockdown. A little over 15,550 people used the Metro service on Monday.

Those who returned to the lifeline had their temperature checked and bags sprinkled with disinfectant as they entered stations, and guards scanned them with metal detectors

attached to poles. The cold blast from the air conditioning vents has given way to a warmer flow of air, a little colder than the atmospheric temperature.

The Delhi Metro Rail Corporation has lost more than Rs 1,500 crore in revenue because of the lockdown and has cut perks of employees by half since last month.
