was planned, operating at speeds of 320 km/h (200 mph). Construction was scheduled to begin in 2008 and work was expected to take around four years, but the project is currently "on hold" due to the financial crisis. The project would join the cities of Buenos Aires and Rosario at a distance of and Córdoba at a distance of . Other projected high-speed rail lines include: Buenos Aires-Mar del Plata (400 km [250 mi]): A new line to the seaside beach resort city and major fishing port of Mar del Plata, south of Buenos Aires city is in the planning stages. Buenos Aires-Mendoza (1200 km [750 mi]) (Planned). Brazil The Rio-São Paulo High Speed rail (; Abbreviation: TAV RJ-SP) is a high-speed rail proposal with the purpose of connecting Brazil's two largest metropoleis: São Paulo and Rio de Janeiro with an extension to Campinas, another metropolis conurbated with São Paulo and 100 km distant from it. The proposed route is through one of Brazil's most mountainous and urbanized terrains resulting the need of around 40% of the tracks to be built through viaducts, bridges and tunnels. Such massive need of structures has made the proposed project's price spike to US$16 billion. Proposed: Brasília – Goiânia – Rio Verde – Itumbiara – Uberlândia – Uberaba – Ribeirão Preto – Campinas – São Paulo – Rio de Janeiro (1200 km). Belo Horizonte – São Paulo (594 km). Curitiba – São Paulo (410 km). Santos – São Paulo (80 km). Brasília – Goiânia (200 km). Track gauge: (standard gauge) Proposed commercial speed: 350 km/h Government mandatory stations: Rio de Janeiro Centre, Rio de Janeiro Intl Airport, Volta Redonda/Barra Mansa, São José dos Campos, São Paulo/Guarulhos Intl Airport, São Paulo Centre, São Paulo/Viracopos Intl Airport and Campinas Centre. Cancelled due to current economic recession. Chile A "high-speed" 200 km/h rail connection between Santiago and Valparaíso was first proposed in 2018 by China Railway Group and again in 2019 by Spanish-based FCC and Talgo via an alternate route through Limache and Til Til. The project was initially planned to open in 2024, but was suspended in 2021 because of the Covid-19 pandemic. Either plan would cost between $2–4 billion, which Pedro Pablo Errazuriz, head of the Chilean state-owned rail firm EFE, said was too expensive to make a priority in 2022. However, in May 2022, President Gabriel Boric's administration has reiterated that the project is
