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 ...
Front of locomotive to the left The single S2, No. 6200, in a PRR promotional image. Under the Whyte notation for the classification of steam locomotives by wheel arrangement, 6-8-6 represents the arrangement of six unpowered leading wheels, eight powered and coupled driving wheels, and six unpowered trailing wheels. Other equivalent ...
Union Pacific 844, the only steam locomotive never retired by a North American Class I railroad. The 4-8-4 wheel arrangement was a progression from the 4-8-2 Mountain type and, like the 2-8-4 Berkshire and 4-6-4 Hudson types, an example of the "Super Power" concept in steam locomotive design that made use of the larger firebox that could be supported by a four-wheel trailing truck, which ...
The Class KF (聯盟型, 'Confederation class', re-designated "ㄎㄈ" or "KF") was a 4-8-4 mainline passenger steam locomotive type built in the United Kingdom by the Vulcan Foundry for the railways of China. Between 1935 and 1936, 24 locomotives were built for the Guangzhou–Hankou Railway, designated as the 600 series. [1]
Only one 2-8-8-8-4 was ever built, a Mallet-type for the Virginian Railway in 1916. [1] Built by Baldwin Locomotive Works, it became the only example of their class XA, so named due to the experimental nature of the locomotive. Like the same railroad's large articulated electrics and the Erie Railroad 2-8-8-8-2s, it was nicknamed "Triplex".
There were only two classes of 4-8-4+4-8-4 steam locomotives worldwide, all of which were constructed by Beyer, Peacock & Company, the owners of the Garratt patent. [1]The predecessor 4-8-2+2-8-4 Double Mountain was likely the optimal Garratt wheel arrangement, with the four-wheeled leading bogies and the two-wheeled trailing trucks on each engine unit ensuring stability at speed and with ...
The Quadruplex was to comprise three articulated engines of 8 driving wheels each beneath the locomotive itself, and a fourth engine beneath the tender.As a compound locomotive, engine cylinders 7 and 9 (as numbered on the above image) would receive high pressure steam to drive the first and third engines, each would exhaust as low-pressure steam to power cylinders 8 and 10 on the second and ...
Grand Trunk Western 6325 ("Old 6325" [1] [2]) is a preserved U-3-b class 4-8-4 "Northern" type steam locomotive built in February 1942 by the American Locomotive Company (ALCO) for the Grand Trunk Western Railroad. As a member of the dual service U-3-b class, the 6325 handled heavy passenger and freight work for the Grand Trunk Western.
