The Highland Railway Drummond 0-6-4T or X class were large tank engines originally intended for banking duty. They were designed by Peter Drummond.
Construction
[edit]The first four were built by the North British Locomotive Company and delivered in 1909. A second batch of four was delivered in 1911.
Design
[edit]The design was derived from that of the class K (0-6-0) tender engines and leading dimensions were very similar although the boiler and firebox are recorded as being 'larger' but by an unspecified amount.
Reputation
[edit]They were not popular with their crews, many thought them heavy and clumsy, and several crews had problems with water capacity. It seems their axleboxes were not well-proportioned either as there are reports of consistent hot box problems.
