Brazil's Transportation Ministry plans an auction in the last quarter of 2009 for the rights to build the country's first high-speed rail line.
Marcelo Perrupato is the ministry's national policy director. He says the 34.6 billion real ($18.4 billion), 317-mile (510-kilometer) line will connect the international airports of Sao Paulo, Campinas and Rio de Janeiro.
Perrupato says in a statement the winning bidder will have to transfer technology.
Perrupato said Thursday that the bullet train will take 105 minutes to travel between Rio de Janeiro and Sao Paulo, a 45-minute plane ride or nearly five-hour car trip.
He did not say when construction would begin. It is expected to begin operating by the 2014 World Cup.
