The Highland Railway W class were four small 0-4-4T locomotives built by the Highland Railway in 1905–1906 to the design of locomotive superintendent Peter Drummond. They were the last engines that were built at the company's Lochgorm works in Inverness, and were used on branch line services.

[edit] Service
All four locomotives passed to the LMS in 1923, where they were numbered 15051-15054 and given power classification '0P'. Locomotive 15052 was withdrawn in 1930, and 15054 followed in the 1940s, but the other two survived to become British Railways 55051 and 55053. These spent their final years based at Helmsdale for working the Dornoch Light Railway, which required locomotives with exceptionally light axle loadings. By the time they were finally withdrawn (in 1956 and 1957 respectively) they were the last former Highland Railway locomotives still in use, and were still in almost original condition.
In order to replace these locomotives, British Railways transferred two GWR 1600 Class 0-6-0PT locomotives (numbers 1646 and 1649) to Helmsdale to work the Dornoch line.
