Brazil has sweetened the rate of return for the teams bidding on August 13 for the 40-year concession to operate the high-speed rail line between Rio de Janeiro and Sâo Paulo, with an extension to Campinas. To improve the economics of the deal, Brazil’s state transportation and logistics agency, Empresa de Planejamento e Logistica (EPL), cut the fee the train operator must pay for use of the rail track infrastructure from Reais 70.31 (US$32.00) to Reais 60 (US$27.00) per km.
