Thats not it, they have also been featured in songs of Bollywood movies set in Mumbai.In the 990s, BEST had a fleet of around 900 double-decker buses but the number gradually declined after the mid-90s.Then, in 2008, BEST cited the high operation cost as the reason to stop inducting double-ducker buses. However, the BEST, since February this year, started replacing these iconic buses with leased battery-run red and black double-decker buses, nearly 255 buses have been introduced so far.Last week, the BEST said it is going to procure open-deck buses for sightseeing and it has already started the process of acquiring them. Until then, the new battery-run double-decker e-buses will be operated for tourists.
