2-12-2

Under the Whyte notation for the classification of steam locomotives, a 2-12-2 locomotive has two leading wheels, twelve driving wheels and two trailing wheels.

Other equivalent classifications are:

UIC classification: 1F1 (also known as German classification and Italian classification)

French classification: 161

Turkish classification: 68

Swiss classification: 6/8

This wheel arrangement is infrequently called "Javanic", after the use of large 2-12-2Ts in Java.
