There's an Amtrak station served by two trains a day within walking distance of my house. I've never once taken that train because according to Amtrak it can't be done. I've tried several times. I'm planning a trip across country, maybe to go visit someone. Hey let's try taking the train. Raleigh NC to Altoona PA...can't be done. Those stations aren't on the same route, and the trip planner on their website can't say "Take the Silver Star to Grand Central in New York then wait around 7 hours then take the Pennsylvanian to Altoona." Neither of these trains will spend much time at 70 miles per hour, both will end up sitting on sidings waiting for freight trains to go by, you've got to catch the train when it goes by at 6 AM or 10 PM, you're going to spend two days on a journey you can do by highway in 8 hours, and it actually costs a little more.
