Swiss classification: '4/6+4/6' The equivalent UIC classification is refined to (2′D)D2′ for simple articulated locomotives. A similar wheel arrangement exists for Garratt locomotives, but is referred to as 4-8-0+0-8-4 since both engine units swivel. 4-8-8-4 Big Boys were only produced for the Union Pacific Railroad. Twenty-five such ...
They went to work on the Cumberland Division's rugged West End subdivision with its more than 2% grades and tight curves, where with the older 2-8-8-0 EL classes, they hauled West Virginia coal and freights. Since the EM-1s had roller bearings throughout, they also handled mail and express trains, replacing two B&O class T-3 4-8-2 Mountains.
Twenty-nine 4-6-2+2-6-4 Garratts, constructed between 1936 and 1941 by Société Franco-Belge in Northern France, operated until the Algerian independence war caused their withdrawal in 1951. This class, designated 231-132BT, was streamlined and featured Cossart motion gear, mechanical stokers and 1.8 m (5 ft 11 in) driving wheels, the largest ...
Thus a 4-6-2-type Garratt is a 4-6-2+2-6-4. For Garratt locomotives, the plus sign is used even when there are no intermediate unpowered wheels, e.g. the LMS Garratt 2-6-0+0-6-2. This is because the two engine units are more than just power bogies. They are complete engines, carrying fuel and water tanks.
Swiss classification: 4/5+4/4+4/6. The equivalent UIC classification is to be refined to (1'D)D(D2') for these engines. 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.
Swiss classification: 4/8 In the UIC classification as applied in Germany and Italy, a rigid-framed locomotive of this arrangement would be 1'D3' , and the Mason bogie (1'D)'3' . Four Mason Bogies of this type were built for the Denver, South Park and Pacific Railroad ; #25 Alpine , #26 Rico , #27 Roaring Fork and #28 Denver .
The largest steam locomotive built in Europe was a 4-8-2+2-8-4 Garratt, built by Beyer, Peacock and Company for the Soviet Railways in 1932. The most numerous Garratt class in the world was also a Double Mountain, the Class GMA and GMAM of the South African Railways, of which 120 were built between 1954 and 1958.
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 ...
