Scope and Content Part of drawing showing detail of a joint between a stiffening beam, upright post and a strut on central bay of Aultnaslanach Railway Viaduct, Moy, Inverness-shire Aultnaslanach Railway Viaduct carries the Aviemore to Inverness railway line which was opened by the Highland Railway Company in 1897. It is the only surviving wooden main-line railway viaduct in Britain. The viaduct has survived because it is better suited to the surrounding boggy ground than heavier metal or masonry bridges. Each of the four central frames is made up of six upright posts simply driven into the ground. This shows a plan of the joint between the horizontal stiffening beam, the upright post and a diagonal strut. The viaduct consists of many complicated joints, which combine to create a strong and stable structure. Source: RCAHMS contribution to SCRAN.
