The Viewliner is a single-level railroad car type operated by Amtrak on most long-distance routes operating east of Chicago. The first production cars, consisting of an order of 50 sleeping cars, entered service in 1994. From 2015-2016, 70 Viewliner II baggage cars entered service. The new baggage cars are used on all Amtrak trains with full baggage cars, both single-level and bi-level, and replaced all of the Heritage Fleet baggage cars that Amtrak inherited from the freight railroads when it was established in 1971. From 2016-2019, 25 Viewliner II dining cars entered service, which replaced all of the Heritage Fleet dining cars. In 2019, 10 Viewliner II baggage-dormitory cars entered service. The last cars to enter service were 25 Viewliner II sleeping cars in 2021.
