{{Short description|Locomotive wheel arrangement}} Under the [[Whyte notation]] for the classification of [[steam locomotive]]s, '''0-2-4''' represents the [[wheel arrangement]] of no [[leading wheel]]s, two powered [[driving wheel]]s on one axle, and four [[trailing wheel]]s on two axles.

==History== [[File:BASA-3K-7-518-1.JPG|thumb|right|Dundee and Newtyle Railway 0-2-4]] This is an unusual wheel arrangement, with the only known examples being [[Earl of Airlie (locomotive)|three locomotives]] supplied to the {{track gauge|4ft6in|lk=on}} [[Dundee and Newtyle Railway]] by [[J and C Carmichael]] of Dundee in 1833.{{sfn|Baxter|1977|p=20}}{{sfn|Baxter|1984|p=20}} These were still in operation in 1847, but may have been scrapped in 1849 when the line was converted to [[standard gauge]].{{cite source|date=December 2025}}

There was also the [[Bristol and Exeter Railway Fairfield steam carriage]], built in 1848 for the Bristol and Exter Railway, who used it on a [[branch line]] before turning it into an {{whyte|0-2-2}} by removing its coach section and two of its trailing wheels, after which it was promptly used for shunting duties.
