It was first assigned to haul freight trains on the N&W mainline before being reassigned to branch line ...The Baldwin 4-8+8-4 750/8DE1 was the Baldwin Locomotive Works ' first attempt at building a road diesel locomotive. The trucks were configured in a 2-D+D-2 wheel arrangement. Only a single test unit was built. In 1943 Baldwin built an experimental "Centipede" as a demonstrator unit, which was assigned road #6000. 4-8-4: 4'-8½" AT&SF: Locomotive Park, 315 W Beale St (US 93), Kingman, AZ: display: Baldwin #60385, 1928: 261: S-3: 4-8-4: 4'-8½" CMStP&P: GN Shops/Minneapolis Junction, Minneapolis, MN: operational: Alco (Schenectady) #71974, 07/1944: Restored to operation in 1993.

Where the axles are coupled by chains or shafts (rather than side rods) or are individually driven, the terms 4w (4-wheeled), 6w (6-wheeled) or 8w (8-wheeled) are generally used. The 2-8-4's 4-wheel trailing truck permitted a huge firebox to be located after the boiler. The resulting greater steaming rate ensured that such a locomotive would never run out of power at speed, a common failing of older locomotives. Applying the ideas of the freight-minded Berkshire type to the Pacific resulted in a 4-6-4 locomotive. The Lima-Southern Pacific GS-4 ("GS" meaning for "Golden State" or "General Service") is a type of semi-streamlined 4-8-4 Northern steam locomotive built by the Lima Locomotive Works in 1941 and 1942 specifically for the Southern Pacific (SP) Railroad. They were assigned road numbers 4430 through 4457. The GS-4s were principally employed on SP's famous "Daylight" streamliners from 1941, but in ...Jim Wrinn. 4-8-4. •YEARS BUILT: 1926 to 1950. •MANUFACTURERS: Baldwin, Lima, Alco, Canadian Locomotive Co., Canadian Pacific Railway, Montreal, Norfolk & Western. •OPERATED ON: Most sizable railroads that provided fast freight and passenger service.4-8-8-4: 4'-8½" UP: UP engine house, Cheyenne, WY: operational: Alco (Schenectady) #69585, 11/1941: From Pomona, CA.
