Locomotives classified 2-6-4 under the Whyte notation of locomotive axle arrangements. The equivalent UIC classification of locomotive axle arrangements is 1C2 or 1'C2' . Subcategories
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]
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.
Sir William Stanier's London, Midland and Scottish Railway (LMS) Class 4P 2-Cylinder 2-6-4T was a class of 206 steam locomotive built between 1935 and 1943. They were based on his LMS 3-Cylinder 2-6-4T .
On the decision to build the BR standard series of locomotives, a series of class four tank engines was ordered, based on the ex-LMS Fairburn 2-6-4T with some modifications. The lineage of the class could therefore be tracked through the LMS/BR Class 4 2-6-4T locomotives back to the Fowler design of 1927.
Thus a 4-6-2-type Garratt is a 4-6-2+2-6-4. For Garratt locomotives, the plus sign is used even when there are no intermediate unpowered wheels, e.g. the LMS Garratt 2-6-0+0-6-2. This is because the two engine units are more than just power bogies. They are complete engines, carrying fuel and water tanks.

The introduction of the 4-6-2 design in 1901 has been described as "a veritable milestone in locomotive progress". [3] On many railways worldwide, Pacific steam locomotives provided the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric or diesel-electric ...
