The Highland Railway's Clan Goods class was a class of steam locomotive. They were designed by Christopher Cumming. The first four (Nos 75 to 78) were built by Hawthorn Leslie and Company on Tyneside, and the maker's plates bore the date 1917, but because of wartime delays were not delivered until 1918. Four more (Nos. 79 to 82) were built in 1919, also by Hawthorn Leslie.

Dimensions

They featured two Robinson type 20+1⁄2 by 26 in (521 by 660 mm) cylinders outside (with long tail-rods), 5 ft 3 in (1.6 m) driving wheel and a boiler set at 175 lbf/in² (1.21 MPa). Locomotive weight was 56 long tons 9 cwt (126,400 lb or 57.4 t).

Transfer to LMS

All eight entered service with the London, Midland and Scottish Railway (LMS) in January 1923. They were classified '5F' by the LMS.

Transfer to BR

Six locomotives survived to enter British Railways (BR) service in 1948, of which five were given BR numbers.
