Are proposed multibillion dollar high-speed railway projects in the United States a smart move or a huge waste of taxpayer dollars?
CNN.com users are challenging politicians, policymakers and each other about whether the Obama administration's push to build high-speed rail lines in the Midwest, West Coast and elsewhere is on the right track.
Many users want proof that high-speed rail can be a profitable, efficient job generator to help raise the sagging U.S. economy when compared with other types of transportation.
Experts -- including the two most powerful congressional lawmakers on rail issues, think-tank specialists and policymakers at the Department of Transportation -- have directly responded to CNN.com user comments.
Interesting (and long) read.
