I just booked a one-way award SAN-PDX on the Pacific Surfliner and the Coast Starlight for next year. I'm very familiar with the Pacific Surfliner and I traveled on the Coast Starlight earlier this year. When I received the booking I noticed that I had roomette #18 on car #1440, which seemed odd to me. Upon reviewing a couple of train forums I found out this is the trans/dorm car. I hear good things and bad things about this car. It's quieter since it's less foot traffic, but you're quite a bit closer to the engines. There is oftentimes a good shower on the upper level of the car. You may or may not be noticed by the attendants, and coffee/tea/water can be a bit of a hike. My question is: have you had the opportunity to travel in such a car, and what were your observations? I'm looking to potentially switch if there's opportunity, and I may switch to a different roomette in the same car as I appear to be next to a toilet.
