Calcutta State Transport Corporation (CSTC) was a West Bengal state government undertaken transport corporation. Headquartered in Kolkata, it was set up on 31 July 1948.[1] Currently it operates under the name WBTC. It plied buses in Kolkata and nearby districts of West Bengal, along with some long distance services. CSTC owned 11 depots in Kolkata and the districts to station its fleet of busses.


Calcutta State Transport Corporation started its journey on 31 July 1948 as State Transport Services with an objective to provide efficient, adequate, economical and properly coordinated passenger bus service particularly in and around the city of Kolkata and in the state of West Bengal in general.

On 15 June 1960 the name of State Transport Service has changed to Calcutta State Transport Corporation (CSTC) under the Road Transport Corporation Act, 1950. By 1966, it had upgraded its services and was connected to 90 percent of the national highways. To fulfill the demand of rural passengers, CSTC introduced one of the earliest Long Distance Bus Services (LDS) from Calcutta to Digha in April 1968.

Merger with WBTC[edit]

In 2017, the Department of Transport (West Bengal), under Transport Minister Suvendu Adhikari merged CSTC with other transport providers such as CTC and WBSTC and to form WBTC.



With a fleet of 782 buses, CSTC was able to set up a number of bus routes in the southern part of West Bengal which were till then not connected to any other means of transport. CSTC also pioneered the running of air-conditioned Volvo buses in Kolkata, replacing the aging fleet.

Air conditioned buses were launched on July 2014 on 40 routes across the city and suburbs. They were in blue and white livery, the buses included a complete fleet of Volvo 8400 units as well as JanBus models from Ashok Leyland, the first low floor front entry public buses in the country. These were bought under the central JNNURM scheme.[2]
