In Whyte notation for the classification of steam locomotives by wheel arrangement, a 2-12-4 is a locomotive with one pair of unpowered leading wheels, followed by six pairs of powered driving wheels, and two pairs of unpowered trailing wheels. While it would be possible to make a tender locomotive of this type, all locomotives of this wheel arrangement were tank engines.
Other equivalent classifications are:
- UIC classification: 1′F2′ (also known as German classification and Italian classification)
- European classification: 1-6-2
- French classification: 162
