In structural detail the Transportation building, with its spacious annex, is one of the simplest and most unassuming of all the Exposition edifices, and yet with a richness of decorative forms that relieves it from poverty of design.
The Transportation building proper was erected on the southwestern bank of the lagoon which surrounds the wooded island forming a portion of the Horticultural grounds.
In the main facade, separated by the lagoon from the hall of Manufactures [545] and Liberal Arts, is the point of architectural emphasis, "the golden doorway," enclosed by a fretted arch or series of arches resplendent with gilding, and with a chaste embroidery of bas-reliefs and arabesques.
However, except in the case of the Amazon, river transport is relatively unimportant in Brazil.
The remaining rail operations are suburban commuter systems connecting in the major cities or specialized railways carrying minerals, timber, or tourists.
Several sectors of the transport system—including railways, metro systems, highways, ports, and airports—were opened to private investment in the 1990s as part of the government’s privatization program.
