Authorized railways are one of the three types of railways provided for in Brazilian railway legislation, alongside concessioned and licensed railways. Under this model, private companies can invest in the construction and operation of railways, making the process more agile and efficient, without the need for traditional public concessions.

This new format directly contributes to the modernization and expansion of the railway network, enabling the creation of new routes and strengthening logistical integration in the country. Whether in the short-line (short-distance) or long-line (long-distance) model, authorized railways play a fundamental role in the development of Brazil's railway infrastructure.
