Still another longstanding project of mine, the fabled Empire Builder, which ran under the GN herald from the early 20th century through the end of private passenger service and still runs under Amtrak to this day. The Great Dome Lounges were massive railcars, requiring 6 wheel trucks, and initially meant for first class passengers only, there were 6 total, 5 owned by GN and the 6th by CBQ.
