The Sociedade de Transportes Coletivos de Brasília Ltda., known as TCB, is a public transport company associated with the Government of Brazil’s Federal District. Its website presents the organization, its leadership, governing documents, structure, strategy, and public-service information. TCB’s work is connected to collective transport in Brasília, although the available site text does not specify routes, fares, or individual transport services.

The website provides information and channels for citizens, including a service charter, contact details, an ombudsman, and the Citizen Information Service. It also offers extensive public transparency resources, such as financial statements, revenue and expenditure records, audit and management reports, contracts, procurement notices, and records of board meetings. Visitors can consult institutional policies, conduct and integrity guidelines, remuneration information, and data-privacy resources. Newsroom materials and the company logo are also available. Through these resources, TCB communicates its institutional responsibilities and makes operational, administrative, and financial information accessible to the public.
