That's actually a very good route length for fast trains, as the airport hassle is non-existent, and much higher speeds are possible for trains than buses--and trains are much roomier. It might work, if the track and signals are up to 100 mph trains. (Or at least might not be a total fiasco...)

Higher gasoline prices and more airline hijacking a will eventually make passenger trains more popular.
This thread reminds me of a conversation with a CN locomotive engineer twenty-some-odd years ago when they were proposing high-speed (100 mph) passenger rail service linking Detroit with Quebec City. He said that the rails were already good enough for 100 mph trains ... the problem was red-necks in pick-up trucks.

Then he reminded me of all the level crossings between Detroit and Quebec City and all the brain-dead red-necks who try to race trains to level crossings. Red-necks lose far too often!
He recounted the time he radioed his boss to report hitting a pick-up truck in Eastern Ontario.
His boss asked "Did you get the license number?"
The locomotive engineer replied "Yes! I have the license number, the license plate and the entire rear bumper hanging off the front end of my locomotive!"
Hah!
Hah!
Bottom line, passenger rail only works when you separate trains, cars and pedestrians on different levels with lots of fences separating them.
