It is very feasible. Last week, fixing the bottleneck that prevents Chicago to Detroit trains from getting into Chicago got funding. The state of Michigan has had a plan to make the current 5:30 trip between Chicago and Detroit take well under 4 hours. If Michigan keeps up its end of the bargin, they should be able to get some federal money in the next few years to execute that vision. It will take more time and money to get the trip down to 2:15 [[like the video), but that is certainly also feasible.

cman710, HSR isn't some green fantasy, where everybody lives sustainably off their little plot of land, it is about growing a more productive economy, using much less energy than the alternatives. Induced demand is exactly the point.
