*has a Post-Train Stress Disorder episode about the ridership on the Lake Country Limited*So Illinois doesn't make the effort to get to Janesville or even Indianapolis.
All sarcasm aside, I'd like to point out that money/efficiency side of things isn't able to play into things like it should be able to in some places. In particular, VA's through trains heading north of WAS are virtually all incremental to Amtrak's bottom line by a substantial amount, but if VA doesn't fund them, Amtrak can't run them.
