Under the Whyte notation for the classification of steam locomotives by wheel arrangement, the 2-8-0+0-8-2 is a Garratt locomotive. The wheel arrangement is effectively two 2-8-0 locomotives operating back to back, with the boiler and cab suspended between the two power units. Each power unit has a single pair of leading wheels in a leading truck, followed by four coupled pairs of driving wheels and no trailing wheels.
A similar wheel arrangement exists for Mallet type locomotives, but is referred to as 2-8-8-2 since only the front engine unit swivels.
This Garratt wheel arrangement was somewhat common, especially for locomotives intended for freight service. The first 2-8-0+0-8-2 locomotive was a single metre gauge locomotive built by Beyer, Peacock & Company in 1924 for the Burma Railways as their class GA.I. The second, and perhaps the better known, was the single Class U1 of the London & North Eastern Railway (LNER), built in 1925.[1][2][3]
