0-8-2T

Under the Whyte notation for the classification of steam locomotives, 0-8-2 represents the wheel arrangement of no leading wheels, eight powered and coupled driving wheels on four axles, and two trailing wheels on one axle (usually in a trailing truck).

Other equivalent classifications are: UIC classification (also known as German classification and Italian classification): D1, French classification: 041, Turkish classification: 45, Swiss classification: 4/5.

This has been a relatively unusual wheel arrangement on mainline railways

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.

Other examples include the LNWR 1185 Class and the Port Talbot Railway 0-8-2T (Cooke) and Port Talbot Railway 0-8-2T (Sharp Stewart).

Dorrigo Steam Railway and Museum has preserved Avonside 0-8-2 Tank Locomotive number 14, formerly operated by South Maitland Railways collieries line in the Hunter Valley of N.S.W. Number 14 is operational, it was built in 1909 in Bristol. The design combination of this 0-8-2 tank Locomotive and the N.S.W. Government Railways 50 class 2-8-0, produced the South Maitland Railways 10 class 2-8-2 Tank Locomotives. Number 14 is the only 0-8-2 in Australia.
