Amtrak currently operates Superliner 1 and Superliner 2 cars. Delivery of the original Superliner 1 cars began in 1979 with the first cars operating on short runs originating in Seattle and Chicago. As more cars arrived, entire Superliner trainsets replaced trains on existing Western routes. The height of a Superliner generally precludes its operating in the Northeast because of tunnel clearance concerns.
Kato's models will be based on the five Superliner 1 car types. They are: Coach-Baggage, Coach, Diner, Sleeper, and Lounge. Over time, some Superliner 1 cars have been modified and some former Coach-Baggage cars are now considered Coach-Smokers (the former baggage area is a smoking lounge). We have chosen the Superliner 1 cars over the Superliner 2 cars because they fill a larger time frame than the Superliner 2, which was first delivered to Amtrak in the 1990s and wears only Phase IV paint.
