What's wrong with the single level eastern LD trains? I actually prefer the Viewliner sleepers to the Superliners, which have insufficient headroom for the upper berths. The Viewliner Dining cars are very nice. The Amfleet 1 coaches are perfectly fine. About the only thing that could be improved is the cafe-lounge car situation, and that can easily be solved in a new car procurement. I've enjoyed my rides on the Cardinal and the Lakeshore Limited, despite the substandard food, and the Silvers now have decent food again in their nice new dining cars. I see no reason why single level trains everywhere shouldn't have great appeal. After all, the classic streamliners were all single level trains.
