ORANGE, RED, AND SILVER IN THE BEIGE DESERT The famous semi-streamlined locomotives of the 1930s and '40s, which were initially assigned to the Southern Pacific's "Daylight" service on the Pacific coast, were strikingly handsome. The big 4-8-4s later hauled all of the S.P.'s premier trains between New Orleans and Seattle. Just two of the sixty GS-class engines survive and one has been restored to its original livery. On June 14, 1984, No. 4449 pulled a perfectly matched train across the desert out of Benson, Arizona, en route from the opening of the Worlds Fair in New Orleans, to Portland, Oregon.
