Locomotives of the Highland Railway

David Jones designed several classes of 4-4-0, and was also notable for introducing the 4-6-0 wheel arrangement to the UK.

A small 2-4-0T purchased secondhand from the Duke of Sutherland also made into LMS ownership.

Fredrick George Smith's brief tenure was cut short by a dispute over his sole design, the 'River' Class 4-6-0.

Christopher Cumming designed one class of 4-4-0 and two types of 4-6-0, totalling 18 locomotives, which all passed to the LMS.

Despite their small numbers, quite a few Highland Railway classes survived well into the LMS era, and even into the 1950s.
