1920-1940 Bombay saw its first bus run on 15 July 1926 between Afghan Church and Crawford Market. The people of Bombay received the bus with enthusiasm, but it took quite some time before this means of conveyance really established itself. For several years, it was looked upon as transport for the upper middle class. Those were the days when the tram was the poor man’s transport; it carried one all the way from Sassoon Dock to Dadar for a mere anna and a half, that was nine paise.
The bus fare for the same journey was four annas, that is 25 paise. In response to the pleas made by the Government and the Bombay Municipal Corporation, the Company extended its services to the northern part of the city in 1934. Double deck buses were introduced in 1937 in order to cope better with the growing traffic. The first Limited Bus service in Bombay, and probably the first in the country as well, started running in 1940 between Colaba and Mahim. Post 1940 BEST- double deckered bus.
BEST Bus in Mumbai Pursuant to the option given to it under the Deed of Concession granted to the Bombay Electric Supply and Tramways Co. Ltd, the Bombay Municipal Corporation acquired on 7 August 1947, the assets of the combined Undertaking, namely the operation of tramways and distribution of electricity in the city of Bombay as a going concern. By mutual agreement, the Corporation also took over the operation of the bus services, which was run by the B. E. S. & T. Company Ltd.
Thus, the Bombay Electric Supply and Transport Company was municipalised and came to be known as Bombay Electric Supply & Transport Undertaking. When the Corporation took over the Company in 1947, there were 242 buses in operation on 23 routes and these buses carried 238,000 passengers per day. At present, there are 4143 buses carrying 450,000 passengers daily on 400+ routes. With the change in the name of the city from Bombay to Mumbai, the organisation is now known as The Brihanmumbai Electric Supply & Transport Undertaking.
