Modi’s visit to Kolkata is part of a continued focus on expanding India’s rail infrastructure, with metro services now in operation in 15 cities in the country. 

The visit comes not long after the PM flagged off the first RRTS service in October, with the first RAPIDX train on the Sahibabad to Duhai section of the $4bn project, which now runs between the country’s capital Delhi and Meerut.
