"Why don't more of us take the train, and why doesn't Washington invest in the rails across the country to give more of the country, and not just the northeast corridor, the pleasure of the Acela, with speeds up to 150 mph between Boston and Washington?" -Peter King, SI
This is a really stupid question. Why would you want travel across the country on speeds of up to 150 mph on a train when you can do so on speeds up to 500 mph in a plane? Trains are a very enjoyable and efficient means of travel for trips under 250 miles (and probably 500 miles for the forseeable future depending on the price of gas).
