In March, Abul Quaiyum bought a reconditioned car and was ready to convert the fuel-run vehicle into a CNG-run one from an authorised conversion centre. He knew it would cost him Tk 60,000, but didn't know where best to go. So he asked a mechanic friend for advice.

Travelling across the country, one would find different modes of vehicles driven by men of varying ages, but Bogra-Shariakandi Road offers a different picture -- a woman ferrying passengers on her CNG-run auto-rickshaw.
