The project has received a political fillip since the present government of Prime Minister Sheikh Hasina took office in January. It is aimed at cleaning up a river, the ferry ghats and introducing environment-friendly transport.

Besides, BRTC officials said the communications ministry was looking for support from the Economic Development Cooperation Fund of South Korea to purchase another fleet of 300 CNG buses.

At present, the corporation has no CNG-run bus in its current fleet of 170 single and double-deckers in the capital.

The state-run transport agency has withdrawn from most of the city routes and limited its services to Volvo double-deckers on a few selected routes, where it recently initiated e-ticketing.
