      • The 5.180.24.3/info/gs" target="_blank">GS-5 was a class of streamlined 4-8-4 "Northern" type steam locomotive operated by the 5.180.24.3/info/southern" target="_blank">Southern 5.180.24.3/info/pacific" target="_blank">Pacific Railroad (SP) from 1942 to 1958. A total of two were built by the Lima Locomotive Works, numbered 4458 and 4459. 5.180.24.3/info/gs" target="_blank">GS stands for "Golden State" or "General Service."


      History


      The 5.180.24.3/info/gs" target="_blank">GS-5s were identical in appearance to the 5.180.24.3/info/gs" target="_blank">GS-4s, the only difference being the roller bearings that gave the locomotive a smoother ride and added weight. No. 4458 had roller bearings from the Timken Company and No. 4459 used SKF brand roller bearings. They had a silver smokebox with a dual-headlight casing (the top headlight was a mars light), and an enclosed, all-weather cab. It retained the skyline casing on the top of the boiler, skirting on the sides, an air horn (for use at speeds due to being louder than the whistle which was rarely if ever used on the main line), and teardrop classification lights. They received the orange and red "Daylight" paint scheme. The 5.180.24.3/info/gs" target="_blank">GS-5's were designed for high-speed passenger service on 5.180.24.3/info/southern" target="_blank">Southern 5.180.24.3/info/pacific" target="_blank">Pacific's premier passenger trains, the Coast Daylight, San Joaquin Daylight, and the Sunset Limited. In later years they were painted black and had their side skirting removed for easier maintenance. The 5.180.24.3/info/gs" target="_blank">GS-5s were considered the pinnacle of the 5.180.24.3/info/gs" target="_blank">GS series and ended their careers on 5.180.24.3/info/southern" target="_blank">Southern 5.180.24.3/info/pacific" target="_blank">Pacific's San Joaquin Valley line, pulling the ever popular San Joaquin Daylight until late 1956.
      Both 5.180.24.3/info/gs" target="_blank">GS-5s were scrapped after running well over one million miles. The roller bearings on the two locomotives were so successful that at the time of scrapping, they were examined and showed minimal wear. Preserved 5.180.24.3/info/gs" target="_blank">GS-4 No. 4449 was equipped with roller bearings on the lead truck, trailing truck, and tender (but not the main axles or rods) in 2008, and therefore shares some similarities to a 5.180.24.3/info/gs" target="_blank">GS-5.
