The lights and sounds came on at 7.5V. The locomotive started moving smoothly at around 11V at a scale 3.5 scale mph. The 4-8-4 achieved at top speed of 79 scale mph at 22V. The full-size GS-4s maximum speed was 110 mph. Engine and idle sounds, brake squeal, and the smoke unit are the only effects available in DC.In the case of a long locomotive like the Big Boy, articulation allowed the engine to operate on tracks with curves as sharp as 20 degrees. ALCO built the Big Boys in Schenectady, New York, and two versions of the engine were made. Starting in 1941, 20 of the 4-8-8-4-1 class engines were made and numbered 4000–4019.The wheel arrangement of small diesel and petrol locomotives can be classified using the same notation as steam locomotives, e.g. 0-4-0, 0-6-0, 0-8-0. 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 St. Louis Southwestern Railroad acquired Northerns at three different times. It bought 10 Class L-1 Northerns in 1930 from the Baldwin Locomotive Works and assigned them road numbers 800 through 809. These 4-8-4s were oil burners with 70" drivers, 26 x 30 cylinders, a boiler pressure of 250 psi, a weight of 419,800 lbs and a tractive effort ...Jun 19, 2006 · Canadian National and its subsidiaries owned North America’s largest fleet of 4-8-4s, including five streamlined versions built in 1936 to haul passenger trains between Montreal and Toronto.

The Nashville, Chattanooga & St. Louis Railroad bought five 4-8-4 locomotives in 1930, which they called "Dixies" (instead of "Northerns" - a name that would seem inappropriate on a fine southern railroad). These 1930 "Dixies" came from the American Locomotive Company and were designated Class J-2 and assigned road numbers 565 through 569.The big J3 engine, the sole survivor of a class of 20 built during the desperate days of World War II, is a 1942 product of the American Locomotive Company.

The considerable weight of the ...

Swiss classification: 4/9; This wheel arrangement was proposed by Lima Locomotive Works in 1949 as a continuation of their "Super Power" concept, essentially an expansion of the 4-8-4. A larger firebox similar to the ones on the 2-6-6-6 locomotives built by Lima would have been fitted, allowing for greater power at speed. Despite promotion by ...Oct 19, 2018 · In 1930, the SP designed a locomotive similar to those Mountains that had a very large firebox (90.4 sq ft) and a four wheel trailing truck to support it. Thus, evolved the Southern Pacific 4-8-4 which was designated Class GS (Golden State) by the SP. In early 1937, six more "Golden States" arrived but this time from the Lima Locomotive Works.
