High speed trains between major cities?[ame=http://en.wikipedia.org/wiki/Acela_Express]Acela [/ame] We can, and did 9 years ago. Our top speed is limited by the need to use existing tracks, but it's still pretty quick. There's a VERY limited market for this kind of travel in the US, and land to build dedicated tracks on is both hard to find, and expensive.
