The description states:
The Route of the Empire Builder extends between Seattle-Portland and Chicago, via Spokane and Minnesota’s Twin Cities. The five de luxe streamliners in this fleet provide daily departures in both directions from every point served. Every travel luxury and comfort is available at no extra fare.
–The Great Northern was merged with other railroads to form the Burlington Northern, and responsibility for the Empire Builder passenger service was assumed by Amtrak.
