The USRA 2-6-6-2 locomotive is a Mallet, or compound articulated type, having both low-pressure and high-pressure cylinders. The smaller high-pressure cylinders powered the rear set of driving wheels, and the larger low-pressure cylinders powered the forward set of driving wheels. The USRA 2-6-6-2 articulated locomotives were direct ...
Overview. The first locomotives of the 2-6-6-2 wheel arrangement were built in 1906 by the Great Northern Railway to permit longer trains on their heavily graded line over the Cascade Mountains. [ 5] They were a refinement of the first North American Mallets, 0-6-6-0 engines built for the Baltimore & Ohio in 1904, with leading and trailing ...
A 2-10-10-2 Mallet locomotive in Winslow, Arizona, in 1913–14. A Mallet locomotive is a type of compound articulated steam locomotive, invented by the Swiss engineer Anatole Mallet (1837–1919). The front of the locomotive is articulated on a bogie. The compound steam system fed steam at boiler pressure to high-pressure cylinders driving the ...
2,2,6,6-Tetramethylpiperidine, abbreviated TMP, HTMP, or TMPH, is an organic compound of the amine class. In appearance, it is a colorless liquid and has a "fishy", amine-like odor. This amine is used in chemistry as a hindered base ( hindered amine ). Although TMP finds limited use per se, its derivatives are a mainstay of hindered amine light ...
2-6-6-0. Under the Whyte notation for the classification of steam locomotives by wheel arrangement, 2-6-6-0 is a locomotive with one pair of unpowered leading wheels, followed by two sets of three pairs of powered driving wheels and no trailing wheels. The wheel arrangement was principally used on Mallet-type articulated locomotives.
In the Whyte notation for the classification of steam locomotive wheel arrangement, a 2-6-6-4 is a locomotive with a two-wheel leading truck, two sets of six driving wheels, and a four-wheel trailing truck. All 2-6-6-4s are simple articulated locomotives . Other equivalent classifications are: UIC classification: (1'C)C2 ' (also known as German ...
2-6-0+0-6-2. Under the Whyte notation for the classification of steam locomotives, 2-6-0+0-6-2 represents the wheel arrangement of an articulated locomotive with two separate swivelling engine units, arranged back to back with the boiler and cab suspended between them. Each engine unit has two leading wheels in a leading truck, six powered and ...
2-6-0+0-6-2. Under the Whyte notation for the classification of steam locomotives by wheel arrangement, 2-6-2+2-6-2 is an articulated locomotive using a pair of 2-6-2 power units back to back, with the boiler and cab suspended between them. The 2-6-2 wheel arrangement has a single pair of leading wheels in a leading truck, followed by three ...
