Mumbai’s first-class local train passengers can finally travel in AC local trains by upgrading their quarterly passes and paying the difference in fare. The fare, however, will have to be paid for the period from when the upgrade was made till the date of expiry of the pass.

Central Railway (CR) chief public relations officer Shivaji Sutar said, “The Centre for Railway Information Systems (CRIS) is tweaking the ticketing software and it will soon be implemented.”
