The Brihanmumbai Electric Supply and Transport (BEST) will start its Premium Bus service on the Thane – Bandra Kurla Complex (BKC) route from December 12, the BEST said.

"The service, called the BEST's Chalo Bus, is being rolled out with four air-conditioned, zero-emission electric buses that promise a convenient and comfortable ride. This launch will make Mumbai the first city in India to have an all-electric premium city bus service," BEST General Manager Lokesh Chandra told mid-day.
