2-4-4-0
In the Whyte notation for the classification of steam locomotive wheel arrangement, a 2-4-4-0 is a locomotive with two leading wheels, two sets of four driving wheels, and no trailing wheels. Examples of this type were constructed as Mallet locomotive, Mallet locomotives. Examples The Chemins de Fer Departmentaux Vivarais and the Chemins de Fer Departmentaux Lozère each possessed 2-4-4-0 Mallet locomotives. The Société Alsacienne de Constructions Mécaniques built three for the Vivarais system in 1908 and two for the Lozère system in 1909. Russian "Class І" (:de:Russische Baureihe І, German Wikipedia) were rare examples of Mallets designed for passenger service. More than 100 were built between 1903 and 1909, and the last were in use until the 1950s. Equivalent classifications Other equivalent classifications are: *UIC classification: 1BB (also known as German classification and Italian classification) *French classification: 120+020 *Turkish classification: 23+22 *Swiss ...

Whyte Notation
The Whyte notation is a classification method for steam locomotives, and some internal combustion locomotives and electric locomotives, by wheel arrangement. It was devised by Frederick Methvan Whyte, and came into use in the early twentieth century following a December 1900 editorial in ''American Engineer and Railroad Journal''. The notation was adopted and remains in use in North America and the United Kingdom to describe the wheel arrangements of steam locomotives, but for modern locomotives, multiple units and trams it has been supplanted by the UIC system in Europe and by the AAR system (essentially a simplification of the UIC system) in North America. However, geared steam locomotives do not use the notation. They are classified by their model and their number of trucks. Structure of the system Basic form The notation in its basic form counts the number of leading wheels, then the number of driving wheels, and finally the number of trailing wheels, numbers ...
