  Two primary railroads are continental: the Transandina, which connects Buenos Aires, in Argentina to Valparaíso, in Chile, and the Brazil–Bolivia Railroad, which makes it the connection between the port of Santos in Brazil and the city of Santa Cruz de la Sierra, in Bolivia.
  
  Two areas of greater density occur in the railway sector: the platinum network, which develops around the Platine region, largely belonging to Argentina, with more than 45,000 km in length; And the Southeast Brazil network, which mainly serves the state of São Paulo, state of Rio de Janeiro and Minas Gerais.
  
  The Argentine rail network, with 47,000 km of tracks, and at one stage was one of the largest in the world and continues to be the most extensive in Latin America. It came to have about 100,000 km of rails, but the lifting of tracks and the emphasis placed on motor transport gradually reduced it. It has four different trails and international connections with Paraguay, Bolivia, Chile, Brazil and Uruguay. The Brazilian railway network has an extension of about 30,000 kilometers. It is basically used for transporting ores. Chile has almost 7,000 km of railways, with connections to Argentina, Bolivia and Peru. Colombia has about 3,500 km of railways.
