West Highland train formations

[MacDuff999]

As part of the planning process for a layout based on the 'old' Fort William station, can anyone please advise what the coach formations (types and numbers) were for the Glasgow, Queen Street (overnight sleeper ex Kings Cross) - Fort William 1950/60's steam-hauled services, also for the usual formation of trains going forward to Mallaig. I have a number of photos of typical 'mixed' trains on the line, but shots of the main passenger services are of litle help in determining the correct coach types in the respective passenger train consists. I think sleepers from KX terminated at Fort William, and that a restaurant car was also included in the ex-KX/Glasgow set, but did that terminate there too? Some photos show Gresley panelled main-line stock, others predominantly Mk. 1's. Also, does anyone know when the NB (what became class 29) diesels first appeared on the line?
