An 0-8-2, in the Whyte notation for the classification of steam locomotives by wheel arrangement, is a locomotive with no leading wheels, eight driving wheels (4 axles) fixed in a rigid frame, and two trailing wheels (normally mounted in a trailing truck).
Other equivalent classifications are:
UIC classification: D1 (also known as German classification and Italian classification)
French classification: 041
Turkish classification: 45
Swiss classification: 4/5
The 0-8-2 was not a common wheel arrangement. In North America, its use was confined to 2-8-2 "Mikado" types assigned to switcher roles; the lead truck was often removed to give more weight on drivers, a guiding truck not being needed at slow speed.
In the United Kingdom, a number of tank locomotive designs were built of the 0-8-2 type, including the London and North Eastern Railway (LNER) R1 class, designed by Henry A. Ivatt and built originally for the Great Northern Railway as their class L1. These locomotives were intended for suburban passenger service, but did not prove satisfactory, so they ended up on freight service.
The 0-8-2 arrangement proved a little more popular on narrow gauge lines, where (due to slow operating speeds) its lack of leading wheels was less important. 0-8-2 locomotives operate, for example, on the Zillertalbahn in Austria, and on the Ravenglass and Eskdale Railway, a miniature railway in England's Lake District.
