Only the South African Class GMA 4-8-2+2-8-4 Double Mountain was more numerous at 120 locomotives. [ 3 ] The 15th class was a development of the RR 16th class 2-8-2+2-8-2 Garratts, to meet a requirement for a locomotive with a larger driving wheel diameter for higher speed train service on the more level parts of the railway.
Union Pacific Challenger No. 3985 is an example of a 4-6-6-4 locomotive. In the Whyte notation for classifying steam locomotives by wheel arrangement, a 4-6-6-4 is a railroad steam locomotive that has four leading wheels followed by two sets of six coupled driving wheels and four trailing wheels . 4-6-6-4's are commonly known as Challengers .
The Pennsylvania Railroad's lone S1 was the only 6-4-4-6 ever constructed. A 6-4-4-6 steam locomotive, in the Whyte notation for describing locomotive wheel arrangements, is one with six leading wheels, two sets of four driving wheels, and six trailing wheels. Other equivalent classifications are:
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, the 4-6-0+0-6-4 is a Garratt locomotive. The wheel arrangement is effectively two 4-6-0 ten-wheeler locomotives operating back to back, with the boiler and cab suspended between the two swivelling power units.
Swiss classification: 3/4+3/5; The UIC classification is refined to (1'C)C2 ' for simple articulated 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 ...

The Lionel Corporation used the 2-6-4 wheel arrangement in many of its model steam locomotives, including the 2037 used in the infamous pastel-coloured Girls' Train. [9] Their 2-6-4 model was based on the Pennsylvania Railroad’s K4 class pacific, even though this was a 4-6-2 rather than a 2-6-4. [10]
A 4-4-6-4, in the Whyte notation for the classification of steam locomotives by wheel arrangement, is one that has four leading wheels followed by four coupled driving wheels, a second set of six coupled driving wheels and four trailing wheels. The Pennsylvania Railroad's Q2 class were the
