  1. 2-6-6-4

    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 have been articulated locomotives, of the Mallet or related simple articulated type. Other equivalent classifications are: ⁕UIC classification: C2' ⁕French classification: 130+032 ⁕Turkish classification: 34+35 ⁕Swiss classification: 3/4+3/5 The UIC classification is refined to C2' for Mallet locomotives. The 2-6-6-4 was a fairly late development, a product of the superpower steam concept, introduced by the Lima Locomotive Works, which encouraged the use of large fireboxes supported by four-wheel trailing trucks. Such a firebox could sustain a rate of steam generation to meet any demands of the locomotive's cylinders, even at high speed. High speeds were certainly among the design goals for a 2-6-6-4; most of the type were intended for use on fast freight trains. The first 2-6-6-4s built in the United States were for the Pittsburgh & West Virginia Railroad, and these were not high speed locomotives but rather mountain luggers. They received three in 1934 and four more in 1937.
