Editing 2-4-2 (section)

==Overview==
The wheel arrangement was widely used on passenger [[tank locomotive]]s during the last three decades of the nineteenth and the first decade of the twentieth centuries. The vast majority of 2-4-2 locomotives were [[Tank locomotive|tank engines]], designated 2-4-2T. The symmetrical wheel arrangement was well suited for a tank locomotive that is used to work in either direction.

When the leading and trailing wheels are in swivelling trucks, the equivalent UIC classification is '''1'B1''''.

While a number of 2-4-2 [[tender locomotive]]s were built, larger tender locomotive types soon became dominant.
