In 1929, GN completed its 7.9-mile Cascade Tunnel, as commemorated in the blotter below. This blotter is from the GN archives at the Minnesota History Center, so I can definitely date it to 1929.
GN President Ralph Budd decided that the faster times allowed by the Cascade Tunnel warranted a new train, so the Oriental Limited was replaced by the Empire Builder as the railway’s premiere train. As the blotter below states, the new train “saves a business day” because it took three nights and two days to get between Chicago and Seattle, compared with the Oriental Limited, which took three nights and three days. This blotter from the Dale Hastin collection has no date but is probably from around 1930.
With its emphasis on low fares, the blotter below from the Dale Hastin collection may be from 1930 or 1931, when the Depression made travelers more price sensitive than amenity sensitive.
