The Superliner is a type of bilevel intercity railroad passenger car used by Amtrak, the national rail passenger carrier in the United States. The design was based on Budd's Hi-Level vehicles, employed by the Santa Fe Railway on its El Capitan trains. Pullman-Standard built 284 cars, known as Superliner I (lounge pictured), from 1975 to 1981; Bombardier Transportation built 195, known as Superliner II, from 1991 to 1996. Car types include coaches, dining cars, lounges, and sleeping cars. Most passenger spaces are on the upper level, which features a row of windows on both sides. Boarding is on the lower level; passengers climb up a center stairwell to access the upper level. The first Superliner I cars entered service in February 1979, with deliveries continuing through 1981. Amtrak assigned the cars to both long-distance and short-distance trains in the Western United States. The first permanent assignment, in October 1979, was to the Chicago–Seattle Empire Builder.
