Rio–São Paulo high-speed rail

The Rio–São Paulo High-Speed Rail (Portuguese: Trem de Alta Velocidade Rio-São Paulo; Abbreviation: TAV RJ-SP) is a planned high-speed rail project to connect São Paulo and Rio de Janeiro. While originally planned to be operational by 2014 in time for the 20th FIFA World Cup, to be held in Brazil at a cost of $9 billion, as of May 2015 formal bidding for the project had yet to start, with the Brazilian government delaying the auction by "at least" one year in August 2013, pushing back hopes of completion to at least the 2020s.
