Amtrak made no effort to disguise the fact that this cover painting by Howard Fogg advertises the Union Pacific Railroad. The other side of the menu also has a small image of a Union Pacific E locomotive, but Amtrak has printed its own name over the UP logo on the nose of that locomotive.
The menu also says it is for the Travelers Rest car. When Amtrak originally took over, it cancelled the North Coast Limited. But it bought many NP passenger cars while not buying many cars from Union Pacific’s passenger fleet. Western Pacific’s and Rio Grande’s California Zephyr cars were not available to Amtrak, so it appears that, for at least a few months, the Traveller’s Rest cars, with their wall-sized paintings depicting the Lewis & Clark Expedition, were used on the San Francisco Zephyr.
It is curious that Amtrak used the more modern spelling, “Travelers Rest,” while Northern Pacific called its car “Traveller’s Rest,” which was the way Lewis & Clark spelled it in their journal. The menu also notes that the dining car relied on the Union Pacific commissary in Omaha.
