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.
