The GS-4 engines were the loco of choice for the Southern Pacific's most prestigious long-distance passenger trains, including the Coast Daylight, the Cascade and the Sunset Limited. Entering service from 1941, the class of 28 engines assumed their glamorous orange and red 'Daylight' livery a few years later, before reverting to black by the mid-1950s. Factory painted by Iron Horse Models, this example features brass construction and captures perfectly the striking presence of the prototype and displays superb performance with formidable haulage capabilities.
