Why is no one talking about high speed rail as an alternative to automobiles in the US? If we would invest in high speed rail (which much of the rail network is already in place), we could easily travel across the country more quickly, while reducing our need to expand expensive highways and airports. Someone once told me that it costs the same to build an on-ramp to a highway as it does to lay 100 miles of railroad track. Getting a country-wide high speed rail network seems so obvious to me, but why is no one talking about it? We're America...we should have the worlds best high speed train system!! Not to mention the jobs it would create in operating and building the system!!!
