Highland Railway Drummond 0-6-4T Class
Encyclopedia
The Highland Railway Drummond 0-6-4T or X class were large tank engines originally intended for banking duty.
Of Peter Drummond design, the first four were built by the North British Locomotive Company
and delivered in 1909. A fifth was delivered in 1910, a sixth in 1911, and the last two in 1912.
The design was derived from that of the 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.
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.
All were withdrawn prior to nationalisation in 1948.
