I haven't been on the Capitol Corridor line and don't know if they use newer, nicer trains than most of Amtrak. I've been on all of the cross country lines and a number of the stretches in the east, which almost exclusively use Superliner cars http://en.wikipedia.org/wiki/Superliner_(railcar) http://en.wikipedia.org/wiki/Superliner_(railcar) and similar single-level coach cars. The difference between these and modern trains is like night and day. The Superliners are noisy and bumpy, with the classic "ka-clump, ka-clump" throughout the journey, and the interiors are cramped and, frequently, colored a drab, stained brown. In contrast, modern trains feel like they are gliding on the tracks with almost no sound (no "ka-clump") and tend to be roomy and comfortable. Indeed, Amtrak's service is horrible, too. The worst case I experienced was paying for a sleeper car for an overnight trip, only to be told as we were being herded onto a single level coach that the sleeper car was broken and we were being downgraded.
