Caledonian Railway 0-4-4T steam locomotives were built for the Caledonian Railway, in Scotland, over many years. Most survived into London, Midland and Scottish Railway (LMS) ownership in 1923 and some into British Railways (BR) ownership in 1948. Designers included Dugald Drummond, John Lambie, John F. McIntosh and William Pickersgill. A development of the Pickersgill design was introduced by the LMS in 1925.

This may simply reflect the amount of fuel and water on board.

Condensing locomotives The 19 and 92 Classes were originally fitted with condensing apparatus for use on Glasgow Central Low Level lines.
