Looking at Amsnag.. I want to go from Chicago to Pasco, Washington, Sleeper. Amsnag shows I have two options: 27 and 7/27. Can anyone explain why the prices for 7/27 are significantly more than the 27? What's the difference between the two? I'm assuming if I book the 7/27 I'll have to physically move from one train to the other when the trains split yet that combination is more expensive than the straight thru 27. I just don't "get it." I'd think the fare for 7/27 would be cheaper since you'd have to get up in the middle of the night and physically move to the other train?? Same thing again on my trip from Portland, OR to Tuscon, AZ.. The options there are weird, too. The 2/422 sleeper is more expensive than the 422. Whats the difference between the "two" trains? (to a "non-rail expert") it's one train....at least it's NOT two entirely separate trains leaving Los Angeles at different times. Also, how often does the Coast Starlight miss the connection at Los Angeles? Does Amtrak pay for hotel/food if the Coast Starlight is late? For 2 days?? Some info from seasoned, experienced train people would be so appreciated......THANKS!! in advance. Nick.
