Amtrak discontinued all LD timetables when they went back to daily service, and many corridor ones are outdated.
Go here for old timetables, dating back to 2005. It is very helpful. Since the Zephyr schedule has not changed (AFAIK, anyway), you can use the one on there. Don't trust the bus connections, or staffed stations though.
