As with many sheds the turntable was a vital part of the set up, engines would usually come on shed be turned, coaled and watered before moving to their allocated shed road prior to their next duty. Depending on the size of shed sometimes physically operating the turntable would have been the responsibility of the loco crew, or as in the case of Salisbury there was a dedicated gang of shed staff allocated to the role.
I have on Fisherton Sarum modelled the turners operating the turntable, although these operators are either static or moving so quickly they only appear as a static blur (delete which ever version you don’t actually believe). The turntable itselfmade from a Peco LK-55 well and deck with scratchbuilt sides, winding mechanism and turners platform for the turners.

I have also modelled the turners gang mess hut that was provided for them to keep warm, dry and rest between turns. At sheds like Salibury the turntable gang was often formed of staff that had previously been in other roles but ended up in such a gang due to a number of reasons such as medical or eyesight issues. Keeping a job being better than no job. I have made use of a Wills SS50 Platelayers hut kit but with the roof replaced with slate tiles rather than the supplied corrugated iron sheeting to more closely represent the one at Salisbury. Stored outside and around the turners mess hut are barrels of lubricating and steam oil.
