It’s common knowledge that the Northeast Corridor is Amtrak’s best line, but the northeast is not the only place in the US where a lot of people ride intercity trains. This map by Michael Hicks shows that California, the area around Chicago, and the Pacific Northwest also stand out as high ridership areas.
In the map, each circle represents one Amtrak station. The larger the circle, the more riders there are at that station.

Note: Map creator Mike Hicks updated the map to remove Amtrak bus connections, and add Canadian cities where Amtrak trains end. This post has been updated with the new map. He also supplies the first draft of a separate close-in map of the Northeast. – February 6, 2013
