Viewliners were developed in the 1990's to replace the remaining "Heritage" sleeping car fleet that had served Amtrak for over 25 years, and had been with the predecessor roads prior to that.
A new modular approach was used for construction of the dorms, sleepers and diners. The shell of the car is physically separate from the interior. During overhauls, the interior modules can be removed to perform structural inspections and repairs. In theory, the interior modules could be replaced or upgraded with a minimum of out-of-service time for the car. Diners could become sleepers, sleepers could become diners. Quite advanced thinking, and perhaps foreseeing a day where diners or sleepers were no longer needed. To date, I'm not aware of any conversions actually taking place, but the concept is certainly interesting.
V-II baggage cars are operated everywhere on the Amtrak system. They'll look right in any Superliner or Viewliner consist. The sleepers, diners, and bag-dorm cars are operated only on trains east of Chicago.
This set includes an assortment of Viewliner II car operated by Amtrak.
