I recently completed a trip from Cincinnati to Martinez on the Cardinal and CA Zephyr in bedrooms (using points thanks to Continental airlines). I found the bunks on the viewliner to be much more comfortable than the superliner. Not only did the viewliner have higher ceilings and window on top bunk, but I found the mattress padding to be thicker and much more comfortable. The upper bunk is also longer and wider. Has anyone else noticed these difference?

I wish Amtrak would use thicker pads on the superliners. These can be very hard for two night trips.
