The Bangalore Metropolitan Transport Corporation (BMTC) has planned to add 700 Tata BS4 buses by March 31, but so far managed only 263.

According to BMTC managing director K R Sreenivas, there has been a delay in supply of the buses from Tata. “Since BS4 uses a new technology, the suppliers have not been able to manufacture in the numbers we require,” he said.
