By the moment the project was announced in 2006, the main form of transportation between these three cities was by road, through National Route 9 (4 lane Highway from Buenos Aires to Rosario and 2 lane route from Rosario to Cordoba -Rosario to Cordoba highway is expected to be finished by 2009-), followed far behind by air travel. The high speed rail would act as an essential component in the revival of railways in Argentina, which would have major impact on the economic development of the region for both faster passenger and cargo connections.
