In the past 30 years I've traveled on the empire builder as far as LaCrosse, Wisconsin; The Starlight and Texas Eagle to Tucson. Now I'd like some feedback on how I should schedule a trip from Seattle to Chicago, then West to either Sacramento or L.A. and back to Seattle without having a layover.
You have few choices. In the direction you suggested:
(1) There is no way to avoid a layover in Chicago. You have to stay overnight.
(2) There is no way to avoid a layover in Sacramento. You have to stay overnight.
(3) You can avoid the layover in LA, but it's tight. If the Southwest Chief gets in 2 hours late, you miss the Coast Starlight.
Sacramento:
Empire Builder from Seattle to Chicago
California Zephyr from Chicago to Sacramento
Coast Starlight from Sacramento to Seattle
Los Angeles:
Empire Builder from Seattle to Chicago
Southwest Chief from Chicago to LA
Coast Starlight from LA to Seattle
If you do the trip in the other direction:
(1) There is still no way to avoid a layover in Chicago. You have to stay overnight.
(2) You can go through Sacramento with no layover -- 3.5 hours between trains
(3) You would need an overnight layover if you go via LA.
Sacramento:
Coast Starlight from Seattle to Sacramento
California Zephyr from Sacramento to Chicago
Empire Builder from Chicago to Seattle
Los Angeles:
Coast Starlight from Seattle to LA
Southwest Chief from LA to Chicago
Empire Builder from Chicago to Seattle
This is all made worse and more complicated by the current less-than-daily schedule, but that's the situation if the trains are running daily.
