was a streamlined 4-8-4
Northern type steam locomotive
that served the Southern Pacific Company
from 1942 to 1958. Only two locomotives were built by the Lima Locomotive Works
and were numbered 4458 and 4459. GS stands for "Golden State" or "General Service."
The GS-5s are exactly identical in appearance to the GS-4
. They only difference was that they were equipped with roller bearings
, which gave the locomotive a much smoother ride and added extra weight. 4458 was equipped with roller bearings from the Timken Company
and 4459 used SKF
brand roller bearings. They featured a silver smokebox
with a dual-headlight casing (top headlight was a mars light), and a fully enclosed, all-weather cab. It retained the skyline casing on the top of the boiler, skirting on the sides, an air horn, teardrop classification lights, and whistles. They received the orange and red "Daylight" paint scheme. The GS-5's were designed for high-speed passenger service on Southern Pacific's premier passenger trains
, the Coast Daylight
, San Joaquin Daylight
and Sunset Limited.
In later years they were painted black and had their side skirting removed for easier maintenance. The GS-5s were considered the best when it came to the GS series, and ended their careers on Southern Pacific's San Joaquin Valley
Neither of the two GS-5 locomotives survive.
