I'll be taking my first Amtrak the last week of March from CHI --> Emeryville (SF)! I had a few questions: 1. If I choose a roommette, is the 2nd bed reserved by another random passenger? Can we put gender preferences at least? I feel slightly uncomfortable that I may be stuck in that tiny space with a not-pleasant person. 2. In a roommette or coach, where I can I store a carry-on bag safely on board? 3. Are there any parts of the route that are high up in height? I'm terrified of heights and absolutely hate the idea of those tracks that are elevated, or along steep mountain cliffs. 4. Have they upgraded to include more outlets in the train?
