"'Higher-speed' trains with many of the same aerodynamic features and interior amenities of France's TGV or Japan's Shinkansen may be the American stepping-stone to true high-speed rail, as the United States looks for affordable improvements to its old-fashioned, slow passenger rail network."
And apparently, these manufacturers are bullish on the prospects for America adopting an incremental approach: "Foreign-based high-speed train-builders, such as Alstom (France), Siemens (Germany), and Talgo (Spain), have opened American factories to make modern trains that can run on conventional tracks in the United States, with hopes of eventually winning high-speed contracts, as well."
