> the only operator on its own tracks

Amtrak only owns ~630 miles of tracks out of the 21,000 it uses, and basically all of that 630 is in the North East. This is definitely Amtrak's best area, although that's partially because of the amount of people going between Boston/NYC/Philadelphia/DC; the rest of the US doesn't have as many big cities that close together.

> multi-state 1000km trip

If you get on I-5 North in Los Angeles and start driving, 1000km later you'll still be in California.
