It's 5.30 on a Thursday evening, when 48-year-old Geeta Ben Vasava makes her way into Platform No. 3 of Mumbai Central railway station. In 20 minutes, her duty will begin when the super-fast express Flying Ranee, leaves for Surat in Gujarat.

The din is palpable as passengers, luggage in tow, rush towards their coaches; some are even seen reaching out to the railway conductor for a last minute reservation. Vasava lumbers through the platform, passively observing this movement, only reacting when she sees a beggar blocking the entrance to one of the coaches. Less than a minute later, the beggar is asked to leave the train, with a strict warning. If not for her stern demeanour, the soft-spoken Vasava doesn't look like a task master. But, the role change happens right after she wears her newly-acquired railway badge.
