Not in my lifetime!
With the federal regulations and everything...this will never leave the speculation stage...at least not for a hundred years or so!
And come-on folks...Here in the shadow of the Nation's capitol, we are trying to extend the Metro rail 8 miles....8 miles people...and already cost over-runs are going to push this out past 5 billion (that's BILLION...with a "B") dollars! By the time it is all said and done, there is speculation that this 8 mile over land low-speed commuter rail will cost in excess of 1 billion dollars per mile...
With this kind of cr@p, how the heck are we to take a story like this seriously? Impossible I say...
