Rail services in India partially resumed on Tuesday despite an ongoing nationwide lockdown.

Thirty special trains were operating today in accordance with government guidance, according to the Ministry of Railways.

All passengers will be screened, and only asymptomatic passengers will be allowed on the trains, according to the Home Ministry. Passengers must also wear face coverings during the journey, and should maintain social distancing.

Indian Prime Minister Narendra Modi said today that the train services were “needed to rev up the economic activity,” but only a limited number of routes would be operational.

Indian railways stopped passenger services for the first time in 167 years on March 24 after a nationwide lockdown was announced. The lockdown will continue through at least May 17.
