The Caledonian Railway 179 Class and 184 Class were 4-6-0 goods engines designed by John F. McIntosh and built in two batches in 1913-14 and 1914-15 respectively, at the Caledonian Railway's own St. Rollox Works. The differences between the two batches were minor, and they are sometimes considered to be a single class.

Overview

They were the last new locomotives designed by McIntosh before his retirement. The type was essentially a superheated version of the earlier 908 Class and were built for use on express goods trains. The locomotives were the most successful of McIntosh's various 4-6-0 designs.[3]

LMS ownership

The locomotives passed into the ownership of the London, Midland and Scottish Railway upon its formation in 1923. They continued in use until they were displaced by new LMS standard locomotives such as the Black Five 4-6-0s.

Disposal

Although they outlasted most of the other McIntosh 4-6-0s they were withdrawn and scrapped between 1934 and 1946,
