Under the Whyte notation for the classification of steam locomotives, a 4-8-8-2 is a locomotive with four leading wheels, two sets of eight driving wheels, and a two-wheel trailing truck. The equivalent UIC classification is refined to (2'D)D1' for simple articulated locomotives. A locomotive of that length must be an articulated locomotive ...
4-8-2+2-8-4. Under the Whyte notation for the classification of steam locomotives by wheel arrangement, a 4-8-2+2-8-4 is a Garratt articulated locomotive consisting of a pair of 4-8-2 engine units back to back, with the boiler and cab suspended between them. The 4-8-2 wheel arrangement has four leading wheels on two axles, usually in a leading ...
The 2-8-8-2 was a design largely limited to American locomotive builders. The last 2-8-8-2 was retired in 1962 from the N&W's roster, two years past the ending of steam though steam was still used on steel mill lines and other railroads until 1983. A similar wheel arrangemement exists for Garratt locomotives, but is referred to as 2-8-0+0-8-2 ...
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 allowed greater production of steam.
The first Czechoslovakian 1’D2’t-h2 (2-8-4) tank locomotive was derived from the CSD Class 455.1 1’D-h2 (2-8-0) tender locomotive, with water tanks, a coal bunker and a trailing bogie added. Apart from changing the drive from the second to the third coupled axle and increasing the superheating surface of the boiler, these handsome tank ...
