2-4-4-0
Steam locomotive wheel arrangement
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 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.[1]
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 1950's.
