The GS-4 runs on four massive 80” drivers, 300lbs psi boiler pressure, and puts out a roaring 5,500 horsepower at 55mph, with a maximum speed of 110 mph. The large drivers gave the locomotive a high top speed; the telling mark of a steam engine built for passenger service. The GS-4 was built for the Southern Pacific Railroad by the Lima Locomotive Works and delivered in the early 1940’s for the SP’s premier passenger trains, finding its way to the Daylight series of name trains. One of the more unique specifications for the GS-4 by the SP was its Mars light, a necessity with the large amount of grade crossings and fog present on the West Coast. The Mars light, like ditch lights on modern locomotives, was utilized as a warning for grade crossings that a high speed train was approaching, its shifting light patterns serving as an eye catcher in foggy conditions.

In the 1940’s, the Southern Pacific “Morning Daylight” was possibly the world’s most beautiful train, its orange and red striping being reserved for the SP’s premier train lines. This “Morning Daylight” consist ran between Los Angeles and San Francisco along the beautiful California coast, past cities such as Ventura, Santa Barbara, Salinas and San Jose. Heading up the “Morning Daylight” was the specially built steam locomotive, the GS-4, one of the most well known steam engines ever designed.

The “Daylight” cars are fitted with operating outer diaphragms, which makes the entire train appear as one contiguous unit rather than separate individual cars. Cars were added and subtracted from the consist as traffic warranted.
