KOLKATA, 13 SEPT: While the Public Vehicles Department and the state transport department continue haggling over the numbers of two-stroke autos scrapped in almost two years after the Calcutta High Court verdict, old but repainted autos continue to rule the city suburbs. Mr Sumantra Chowdhury, state transport secretary, said that till August 2010, more than 17,000 two-stroke autos have been scrapped. About 20,000 registered autos were phased out after Calcutta High Court banned two-stroke autos from plying in the Kolkata Municipal Area.
