Bus services in Kolkata started in the year 1920 but were unorganised. The organized road transport in the public sector was given shape on 31 July 1948 with the creation of State Transport Services under the Directorate of Transportation, Government of West Bengal. It started operations on 6 intracity routes, with a fleet of 25 buses. Diesel era started with the addition of 2 Double Decker buses in 1949-50. Then the STS became self-sustainable with the establishment of depots and terminals. Gradually the structure of State Transport Services turned into a full-fledged organization with spreading its network of operation throughout the entire city. After about 12 years, State Transport Services became CSTC on 15 June 1960. This was the start of a new era for the public transport system in the city and state. Up to 1966-67 CSTC nationalized about 90% of the City routes. After that CSTC could not sustain the increased passenger demands in the city mainly due to the financial constraints. Since then the Government decided to allow private buses to operate in CSTC routes and areas. It also started operating on long-distance routes, starting with CalcuttaDigha in 1968. Over the years, with rapid expansions of long-distance operations, CSTC connected remote rural areas of the state with Kolkata. Soon, it covered almost the whole state and connected the district headquarter towns. In the year 1989, a new body was formed, named West Bengal Inland Water Transport Corporation Limited, for the operation of Vessel services. It started with the Ferry Service on the Hoogly and the Muriganga rivers. Later this was merged into West Bengal State Transport Corporation, which provided bus services in Kolkata and different areas of South 24-Parganas, along with the CSTC. In June 2016, WBSTC, CTC and CSTC were merged into one with operational name WBTC. Till the merge, WBSTC had a fleet of 233 buses.
