A New Locomotive Project, Stroudley HR56 Dornoch.

 All 6 of HR56's wheels are similar and solid with 2 small opposed holes. 

Three 0-6-0T engines to William Stroudley's design were constructed at Lochgorm Works, the first and the subject of my model was number 56, built in 1869 and originally named "Balnain". The engine was substantially rebuilt in 1896 when it gained its Jones chimney. By 1910 a rear bunker had been added and the engine, renamed "Dornoch", was turned out in unlined olive green livery, which rather suits my painting skills. In 1917 her good looks were compromised when the tanks were extended back to the cab, thus drawing a line under my interest in the engine. My model will be built to illustrate HR56 in the condition in which it ran between 1910-17.

Photos of no.56 in Highland Railway livery are in short supply, I have found five though non of these shows the engine in my chosen time slot. There are a further six photos extant which show the engine in LMS days and these are of value as they show details inherited from earlier days. The model will be scratch built, though it will depend on castings from Laurie Griffin, who made fittings for a kit which never materialised, and without which my model would be a non-starter.

HR56 is in most respects similar to HR57 "Lochgorm" and a  drawing by Laurie Ward of the latter is my starting point. There are a surprising number of differences between the sister engines each of which will be noted and incorporated in my model. In addition to Laurie's drawing there is a very useful article by Charles Wrigley in HRJ 107 (Autumn 2013) concerning the differing braking arrangements of the Stroudley tanks.

The chassis has already had a test run on the club layout in Carlisle and proved a good runner. The motor gearbox is an ABCgears Mini7S with an M1824 which provides ample power though there is no space for a flywheel. Pick-ups are wires bearing on the back of the left hand wheels while the wheels on the right hand side are shorted out.

The overlays to the wheels are etches from my own design left over from building HR 57 some time ago.
